Threshold public-key encryption (TPKE) allows a set of users to decrypt a ciphertext if a given threshold of authorized users cooperate. Existing TPKE schemes suffer from either lo...

We construct the first public-key encryption scheme in the Bounded-Retrieval Model (BRM), providing security against various forms of adversarial “key leakage” attacks. In th...

We present a fully homomorphic encryption scheme which has both relatively small key and ciphertext size. Our construction follows that of Gentry by producing a fully homomorphic s...

This paper proposes an efficient approach for managing the security in WSN. Our approach uses the notion of public key cryptography in which two different keys are used for encrypt...

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 ...
