We show a general framework for constructing password-based authenticated key-
exchange protocols with optimal round complexity—one message per party, sent …

Abstract Authenticated Key Exchange (AKE) is a cryptographic scheme with the aim to
establish a high-entropy and secret session key over a insecure communications network …

Protocols for password-based authenticated key exchange (PAKE) allow two users who
share only a short, low-entropy password to agree on a cryptographically strong session …

Increasingly connectivity becomes integrated in products and devices that previously
operated in a stand-alone setting. This observation holds for many consumer ap-plications …

Abstract An Ideal Cipher (IC) is a cipher where each key defines a random permutation on
the domain. Ideal Cipher on a group has many attractive applications, eg, the Encrypted Key …

Password-based authenticated key exchange () protocol, a widely used authentication
mechanism to realize secure communication, allows protocol participants to establish a high …

OPAQUE [Jarecki et al., Eurocrypt 2018] is an asymmetric password authenticated key
exchange (aPAKE) protocol that is being developed as an Internet standard and for use …

Protocols for password authenticated key exchange (PAKE) allow two parties who share
only a weak password to agree on a cryptographic key. We revisit the notion of PAKE in the …

Abstract Password Authenticated Key Exchange (PAKE) have become a key building block
in many security products as they provide interesting efficiency/security trade-offs. Indeed, a …

Consider key agreement by two parties who start out knowing a common secret (which we
refer to as “pass-string”, a generalization of “password”), but face two complications:(1) the …
