Bi-Deniable Public-Key Encryption
In CRYPTO 1997, Canetti et al.put forward the intruiging notion of deniable encryption, which (informally) allows a sender and/or receiver, having already performed some encrypted...

Algebraic Cryptanalysis of the PKC'2009 Algebraic Surface Cryptosystem
Abstract. In this paper, we fully break the Algebraic Surface Cryptosystem (ASC for short) proposed at PKC’2009 [3]. This system is based on an unusual problem in multivariate cr...

A secure unidirectional proxy re-encryption using identity and secret key exchange
Proxy re-encryption, abbreviated as PRE, is a cryptosystem which allows the proxy to re-encrypt a cirphertext without accessing the underlying message. The re-encryption protocol ...

Homomorphic encryption from codes
We propose a new homomorphic encryption scheme based on the hardness of decoding under independent random noise from certain affine families of codes. Unlike in previous latticeba...
