Abstract. We describe a public-key encryption scheme based on lattices — specifically, based on the hardness of the learning with error (LWE) problem — that is secure against ...
Abstract—Password-authenticated key exchange (PAKE) protocols are designed to be secure even when the secret key used for authentication is a human-memorable password. In this pa...
We consider one-round key exchange protocols secure in the standard model. The security analysis uses the powerful security model of Canetti and Krawczyk and a natural extension of...
Public key based authentication and key exchange protocols are not usually designed with privacy in mind and thus involve cleartext exchanges of identities and certificates before ...
Abstract— In this paper, we propose a non-commutative keyexchange scheme which generalizes the classical ElGamal Cipher to polycyclic groups. We will explore other classes of gro...
