Abstract. The use of passwords in security protocols is particularly delicate because of the possibility of off-line guessing attacks. We study password-based protocols in the cont...
pwdArmor is a framework for fortifying conventional password-based authentications. Many password protocols are performed within an encrypted tunnel (e.g., TLS) to prevent the exp...
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. 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 ...
