We define a new notion of relatively-sound non-interactive zeroknowledge (NIZK) proofs, where a private verifier with access to a trapdoor continues to be sound even when the Ad...
Abstract. An unresolved problem in research on authenticated key exchange (AKE) is to construct a secure protocol against advanced attacks such as key compromise impersonation and ...
Password Authenticated Key Exchange (PAKE) is one of the important topics in cryptography. It aims to address a practical security problem: how to establish secure communication be...
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 ...
