Efficient lattice-based signature scheme
: In Crypto 1997, Goldreich, Goldwasser and Halevi (GGH) proposed a lattice analogue of McEliece public key cryptosystem, in which security is related to the hardness of approximat...

Chosen-Ciphertext Secure Proxy Re-encryption without Pairings
Proxy re-encryption (PRE), introduced by Blaze, Bleumer and Strauss, allows a semi-trusted proxy to convert a ciphertext originally intended for Alice into an encryption of the sa...

Conditional proxy re-encryption secure against chosen-ciphertext attack
In a proxy re-encryption (PRE) scheme [4], a proxy, authorized by Alice, transforms messages encrypted under Alice's public key into encryptions under Bob's public key w...

Dimension of the Linearization Equations of the Matsumoto-Imai Cryptosystems
Abstract. The Matsumoto-Imai (MI) cryptosystem was the ļ¬rst multivariate public key cryptosystem proposed for practical use. Though MI is now considered insecure due to Patarinā€...
