Secure multi-party computation protocol using asymmetric encryption
Privacy preservation is very essential in various real life applications such as medical science and financial analysis. This paper focuses on implementation of an asymmetric secure multi-party computation protocol using anonymization and public-key encryption where all parties have access to trusted third party (TTP) who (1) doesn't add any contribution to computation (2) doesn't know who is the owner of the input received (3) has large number of resources (4) decryption key is known to trusted third party (TTP) to get the actual input for computation of final result. In this environment, concern is to design a protocol which deploys TTP for computation. It is proposed that the protocol is very proficient (in terms of secure computation and individual privacy) for the parties than the other available protocols. The solution incorporates protocol using asymmetric encryption scheme where any party can encrypt a message with the public key but decryption can be done by only the possessor of the decryption key (private key). As the protocol works on asymmetric encryption and packetization it ensures following: (1) Confidentiality (Anonymity) (2) Security (3) Privacy (Data). 2014 IEEE. -
Secure medical sensor monitoring framework using novel optimal encryption algorithm driven by Internet of Things
Recently, healthcare monitoring systems have emerged as significant tolls for constant monitoring of patient's physiological characteristics. These systems use implanted sensors. IoT (Internet of Things) have revolutionized healthcare systems where health care equipment's are equipped with many sensors that actively collect data from patients and pass it on to cloud based storages using gateway sensors. Securing data have been significant barriers in many applications as false information get injected, or important information are modified or stolen at different phases of health care systems dependent on IoT. The attacks can also result in fatalities making it imperative to secure IoT based health care systems. A Hybrid technique combining MOAES (Modified Optimal Advanced Encryption Standard) with CM (Chaotic Map) Encryptions called HMOAES-CM technique is proposed. This technique can be helpful in securely accessing the patient data over online mode, and in addition, the data sharing can be performed in an encrypted form for the necessary targets of stakeholders. The proposed authentication approach is aimed at IoT, which is resilient to all kinds of network attacks and its implementation is also simpler. Comparing the suggested work to similar works, the level of evaluation is much improved. 2023 The Authors -

Secure key exchange scheme: A DNA computing-based approach to resist MITM in DHKE
Diffie-Hellman key exchange (DHKE) protocol was a pioneering work and considered as a new direction in the field of cryptography though it is not an encryption protocol. DHKE is a method to exchange the keys securely, based on the discrete logarithm problem. It has applications in internet security protocols including SSL, IP Sec and SSH. The major issue with DHKE is its vulnerability to man in the middle attack (MITM). Various techniques have been proposed to resist the MITM including digital signatures. This paper proposes DNA computing-based encryption techniques to resist MITM in DHKE. DNA cryptography builds on the concepts of biomolecular computations which are considered as one of the emerging directions in the cryptography. The proposed methodology also includes an encryption technique based on DNA-based codebook, secret sharing and DNA cryptography to exchange parameters securely. The security analysis of the proposed scheme is evaluated by theoretical analysis. Formal analysis of the proposed protocol is done using Scyther and all the modelled claims are validated and positive results are obtained. Copyright 2021 Inderscience Enterprises Ltd. -
Secure Image Transmission Scheme based on DNA Sequences
Cryptography and steganography are the most widely utilized and adopted fields of secure data communication. Data transfer can be secured using a combination of these methods. The data is transmitted from sender to receiver using cryptography, the most secure method. At the same time, steganography performs the information hiding in the form of video, image, or text within a cover image. The sensitive data is hidden, so it is not visible to the human eye. The data is stored and transferred more securely by adding DNA technology to the cryptography. It provides additional data security level and is most commonly employed to implement computation. This research developed a new method for combining cryptography with steganography. There are two phases to the proposed method: image encryption and hide phases and image extraction phases. Encryption is done by using the Signcryption algorithm. Four standard images were utilized as test material for the evaluation. Four factors are used to determine the performance of the proposed method as Peak signal-to-noise ratio (PSNR), Mean Square Error, Entropy, and Structural Similarity Index Measure (SSIM) for hiding and extracting the messages. The implementation is done in python. The proposed method achieves better performance when compared to the previously published works. 2022 Seventh Sense Research Group -

Secure Identity Based Authentication for Emergency Communications
The Vehicular Ad Hoc Network (VANET) offers secure data transmission between vehicles with the support of reliable authorities and RSUs. RSUs are fully damaged in emergency scenarios like natural catastrophes and are unable to provide the needed services. Vehicles in this scenario must communicate safely without RSUs. Hence, this study suggests a secure and reliable identity-based authentication technique for emergency scenarios. To provide secure vehicle-to-vehicle communication without RSUs, ECC-based IBS is utilized. Additionally, it offers security features like message integrity, privacy protection, and authentication. It is also resistant to attacks depending on authentication and privacy. The proposed technique performs efficiently with less communication and computing cost when its performance is compared with recent schemes.

Secure biometric authentication with de-duplication on distributed cloud storage
Cloud computing is one of the evolving fields of technology, which allows storage, access of data, programs, and their execution over the internet with offering a variety of information related services. With cloud information services, it is essential for information to be saved securely and to be distributed safely across numerous users. Cloud information storage has suffered from issues related to information integrity, data security, and information access by unauthenticated users. The distribution and storage of data among several users are highly scalable and cost-efficient but results in data redundancy and security issues. In this article, a biometric authentication scheme is proposed for the requested users to give access permission in a cloud-distributed environment and, at the same time, alleviate data redundancy. To achieve this, a cryptographic technique is used by service providers to generate the bio-key for authentication, which will be accessible only to authenticated users. A Gabor filter with distributed security and encryption using XOR operations is used to generate the proposed bio-key (biometric generated key) and avoid data deduplication in the cloud, ensuring avoidance of data redundancy and security. The proposed method is compared with existing algorithms, such as convergent encryption (CE), leakage resilient (LR), randomized convergent encryption (RCE), secure de-duplication scheme (SDS), to evaluate the de-duplication performance. Our comparative analysis shows that our proposed scheme results in smaller computation and communication costs than existing schemes. 2021 M et al. All Rights Reserved. -
Secure Authentication Schemes for Vehicular Adhoc Networks: A Survey
Vehicular Adhoc Network (VANET) is based on theprinciples of Mobile Adhoc NETwork (MANET) where vehicles are considered as nodes and secure communication is established to provide asafe driving experience. Due to its unique characteristics, it has various issues and challenges. These issues can be resolved by ensuring security requirements like authentication, privacy preservation, message integrity, non-repudiation, linkability, availability etc. Authentication plays a vital role since it is the first step to establish secure communication in the vehicular network. It also distinguishes malicious vehicles from legitimate vehicles. Different authentication schemes have been proposed to establish secure vehicular communications. A survey of the existing authentication schemes is given in this paper. At first, the existing authentication schemes are broadly classified based on message signing and verification methods. Then, each category is clearly explained with its sub-categories. At last, the existing schemes in each category are compared based on security requirements, security attacks and performance parameters. 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. -
Secure authentication framework for cloud
The growing popularity of cloud based services is prompting organizations to consider shifting applications and data onto cloud. However, organizations dealing with highly sensitive information are apprehensive of moving its applications & data to public cloud owing to concern about security of its information. It is hence incumbent on service providers that only legitimate Users will access its services and resources in cloud. Verifying authenticity of remote users is a necessary pre-requisite in a cloud environment before allowing access to secure resources/services/ applications. The simplest & most commonly used user authentication mechanism is password based authentication. However, Users tend to choose easy to remember password, and many a times use same password for multiple accounts, which makes it often the weakest link in security. Furthermore, service providers authenticating Users on the basis of password, stores password verification information in their databases and such authentication schemes with verification table are known to be vulnerable to various attacks. From the perspective of authentication requirements, service providers in a cloud environment can be broadly categorized into two. Those service providers dealing with highly sensitive information and working in a regulated environment can be grouped into category one ?? as in those offering services for sectors like health care, finance. These providers require a strong and secure authentication mechanism to authenticate its users, without any additional functionality. Similarly, there is a second category of service providers dealing with secure information but operate in a collaborative environment ?? as providers providing their applications bundled through a web portal. To provide the Users with a seamless authentication experience, while accessing multiple services during a session, the second category of service providers prefer to have Single Signon functionality. Two-factor authentication technology overcomes the limitations of password authentication and decreases the probability that the claimant is presenting false evidence of its identity to verifier. If different service providers set up their own two-factor authentication services, Users have to do registration and login process repeatedly. Also, Users accessing multiple cloud services may be required to hold multiple authentication tokens associated with various service providers. Authentication factors such as crypto-tokens and smart cards with cryptographic capabilities have been vastly used as a second authentication factor. However, Users are required to always carry these authentication tokens which make it cumbersome from practical usability perspective. Also its usage involves cost thus restricting its adoption to corporate environments. The authentication process can be made more user-convenient if the authentication factor chosen is such that it is commonly used by all types of Users. Leveraging the use of mobile phone as an authentication factor can help address issue of user convenience at no extra cost while improving the security of authentication schemes. Though, there has been an increasing focus on strengthening the authentication methods of cloud service users, there is no significant work that discusses an authentication scheme that can be adopted by the two categories of cloud Service Providers. Taking cognizance of aforesaid issues related to secured authentication in cloud environment, this research focused on designing secure Two-Factor authentication schemes that can be adopted by the two categories of service providers. This research carried out in different levels, proposes authentication architecture and protocols for the two categories of service providers. At the first level, research proposes Direct Authentication architecture for cloud Service Providers who prefer to authenticate its users by using a strong authentication mechanism and does not require Single Sign-On (SSO) functionality. For those Providers who prefer to provide its user with a SSO functionality the research proposes Brokered Authentication architecture. The next level of research focuses on proposing User Authentication Protocols for both Direct Authentication Service Providers (DASPs) and Brokered Authentication Service Providers (BASPs). The research proposes use of strong, Two-Factor Authentication Protocols without Verifier Table. The suggested protocols, provides Users with flexibility of using a Password and either a Crypto-token or a Mobile-token to authenticate with Service Providers. The proposed approach eliminates the requirement of the User to remember multiple identities to access multiple services and provides the benefit of a higher level of security on account of second authentication factor and non-maintenance of verifier table at server. Access to different services offered by multiple service providers using a single authentication token requires interoperability between providers. Also, the Service Providers will have to address the task of issuing the second authentication factor to Users. As a result, the research intends to propose the utilization of proposed two-factor authentication scheme within a specific environment which includes a trusted entity called an Identity Provider (IdP), with whom Users and Service Providers will be registered. The IdP is responsible for issuing and managing the second authentication factor. In brokered authentication, the IdP playing the role of an authentication broker also provides Single Sign-on functionality. The Security Assertion Markup Language (SAML) is used by BASPs and the IdP to exchange authentication information about Users. A major objective of this research is to propose an authentication model that can be adopted by both categories of service providers. Hence, this research proposes an authentication framework for cloud which supports an integrated authentication architecture that provides the service providers with the flexibility to choose between direct and brokered authentication. The integrated two-factor authentication protocol, which does not require the server to maintain a verifier table, supported by the frame work allows users to do a single registration and access services of both direct & brokered authentication service providers using the same crypto-token/mobile-token. To verify claims about security strengths of the proposed authentication protocols, security analysis is done using theoretical intuition. The proposed protocols are found to offer desirable security features such as resistance to replay attack, stolen verifier attack, guessing attack, user impersonation attack etc. To verify the efficiency of the proposed protocols, the communication and computation costs are compared with similar schemes and it is seen that the costs are comparable. To validate the resistance of protocols to authentication attacks, they are analyzed using automated verification tool called ????Scyther??? and the protocol strength is verified by ???no attacks??? results. -
