description: Combining reverse firewalls and reencryption in a PEKS (Public Key Encryption with Keyword Search) model introduces a powerful way to mitigate malicious client behaviour and enhance privacy, especially in untrusted or semi-trusted environments. A reverse firewall is a client-side monitor or proxy that sits between a cryptographic application and the network. Its goal is to ensure that compromised software does not leak any information, even if the software is compromised. In this context a reverse firewall supported with Proxy re-encryption (PRE) supports a secured scheme for applications which require high level of security in public domain scenarios like Cloud for data sharing forms. For schemes which require good level of Identity applications and also needs the support of data Integrity, reverse firewall associated with Re encryption may be a suitable choice. The model is refined with conditional time stamp in accepting the keys for re encryption process. As this model can use different random numbers at different levels of Reverse firewall and re encryption, makes the work free from Chosen cipher text attacks. Also, the proposed model supports Design, Modelling and security analysis in a real time environment. 2025 IEEE.
