Security of human video objects by incorporating a chaos-based feedback cryptographic scheme
Security of multimedia files attracts more and more attention and many encryption methods have been proposed in literature. However most cryptographic systems deal with multimedia...

Public Key Compression and Modulus Switching for Fully Homomorphic Encryption over the Integers
We describe a compression technique that reduces the public key size of van Dijk, Gentry, Halevi and Vaikuntanathan’s (DGHV) fully homomorphic scheme over the integers from ËœO(Î...

Targeted Malleability: Homomorphic Encryption for Restricted Computations
We put forward the notion of targeted malleability: given a homomorphic encryption scheme, in various scenarios we would like to restrict the homomorphic computations one can perf...

Fully Homomorphic Encryption from Ring-LWE and Security for Key Dependent Messages
We present a somewhat homomorphic encryption scheme that is both very simple to describe and analyze, and whose security (quantumly) reduces to the worst-case hardness of problems ...
