Security against selective opening attack (SOA) requires that in a multi-user setting, even if an adversary has access to all ciphertexts from users, and adaptively corrupts some fraction of the use...
We study homomorphic authenticated encryption, where privacy and authenticity of data are protected simultaneously. We define homomorphic versions of various security notions for privacy and authentic...
We propose a simple and ecient construction of CCA- secure public-key encryption scheme based on lattice. Our construction needs an encryption scheme, which we call \matrix encryption", as building...
We propose a new variant of the Cramer-Shoup KEM (key encapsulation mechanism). The proposed variant is more cient than the original Cramer-Shoup KEM scheme in terms of public key size and encapsu...
A new public key encryption scheme, along with several variants, is proposed and analyzed. The scheme and its variants are quite practical, and are proved secure against adaptive chosen ciphertext a...
A (public key) Trace and Revoke Scheme combines the functionality of broadcast encryption with the capability of traitor tracing. Specifically, (1) a trusted center publishes a single public key and ...
