We show that, in the ideal-cipher model, triple encryption (the cascade of three independently-keyed blockciphers) is more secure than single or double encryption, thereby resolvin...
We present two machine-checked proofs of the existential unforgeability under adaptive chosen-message attacks of the Full Domain Hash signature scheme. These proofs formalize the ...
We have designed and implemented a general and powerful distributed authentication framework based on higher-order logic. Authentication frameworks — including Taos, SPKI, SDSI,...
Abstract. We present EasyCrypt, an automated tool for elaborating security proofs of cryptographic systems from proof sketches—compact, formal representations of the essence of a...
