Blind signatures (BS), introduced by Chaum, have become a cornerstone in privacy-oriented cryptography. Using hard lattice problems, such as the shortest vector problem, as the bas...
Anonymous channels or similar techniques that can achieve sender's anonymity play important roles in many applications. However, they will be meaningless if cryptographic prim...
: We describe methods for automatically identifying signature blocks and reply lines in plaintext email messages. This analysis has many potential applications, such as preprocessi...
Group encryption (GE) schemes, introduced at Asiacrypt’07, are an encryption analogue of group signatures with a number of interesting applications. They allow a sender to encryp...
