Title A name given to the resource An efficient nonlinear access policy based on quadratic residue for ciphertext policy attribute based encryption Subject The topic of the resource Access policy; Ciphertext policy attribute based encryption; Encryption; Non-linear secret- sharing scheme; Quadratic residue Description An account of the resource Ciphertext Policy Attribute Based Encryption (CP-ABE) is an efficient encryption scheme as data owner is making decision about the attributes that can access his data and adding that attributes to access structure while encrypting that message. Most existing CP-ABE scheme are based traditional access structure such as linear secret sharing scheme which incur large ciphertext size and linearly increases according to the number of attributes. And those schemes have more computational overhead for calculating share for each attribute and when recalculating secret in data user side. In this paper, we propose a different secret sharing scheme that can be used in access policy for CP-ABE which will reduce the size of ciphertext and there by communication overhead. Furthermore, the proposed scheme reduced computational overhead of secret sharing scheme and improved overall efficiency of the scheme. 2021 Little Lion Scientific Creator An entity primarily responsible for making the resource Ancy P.R.; Krishna A.V.N.
