NTRUEncrypt is unusual among public-key cryptosystems in that, with standard parameters, validly generated ciphertexts can fail to decrypt. This affects the provable security prop...

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...
One of the important applications of digital signature is anonymous credential or pseudonym system. In these scenarios, it is essential that the identity of the signer is kept secr...
We describe two new paradigms on how to obtain ordinary signatures that are secure against existential forgery under adaptively chosen message attacks (fully-secure, in short), fro...

The Fiat-Shamir (FS) transform is a popular tool to produce particularly efficient digital signature schemes out of identification protocols. It is known that the resulting signat...
