Automating Computational Proofs for Public-Key-Based Key Exchange [PDF]
, 2010 We present an approach to automating computationally sound proofs of key exchange protocols based on public-key encryption. We show that satisfying the property called occultness in the Dolev-Yao model guarantees the security of a related key exchange protocol in a simple computational model.

On the leakage-resilient key exchange [PDF]
Journal of Mathematical Cryptology, 2017 Typically, secure channels are constructed from an authenticated key exchange (AKE) protocol, which authenticates the communicating parties based on long-term public keys and establishes secret session keys.

Efficient Password-Based Authenticated Key Exchange Without Public Information [PDF]
, 2007 Since the first password-based authenticated key exchange (PAKE) was proposed, it has enjoyed a considerable amount of interest from the cryptographic research community. To our best knowledge, most of proposed PAKEs based on Diffie-Hellman key exchange need some public information, such as generators of a finite cyclic group.

Journal of Mathematical Cryptology, 2022 Rahman and Shpilrain proposed a Diffie–Hellman style key exchange based on a semidirect product of n×nn\times n-matrices over a finite field. We show that, using public information, an adversary can recover the agreed upon secret key by solving a system ...

Remarks on a Tropical Key Exchange System
Journal of Mathematical Cryptology, 2020 We consider a key-exchange protocol based on matrices over a tropical semiring which was recently proposed in [2]. We show that a particular private parameter of that protocol can be recovered with a simple binary search, rendering it insecure.

A New Class of Strongly Asymmetric PKA Algorithms: SAA-5
Cryptography, 2019 A new class of public key agreement (PKA) algorithms called strongly-asymmetric algorithms (SAA) was introduced in a previous paper by some of the present authors.

New approach to practical leakage-resilient public-key cryptography
Journal of Mathematical Cryptology, 2020 We present a new approach to construct several leakage-resilient cryptographic primitives, including leakage-resilient public-key encryption (PKE) schemes, authenticated key exchange (AKE) protocols and low-latency key exchange (LLKE) protocols.

Non-Invertible Public Key Certificates
Entropy, 2021 Post-quantum public cryptosystems introduced so far do not define a scalable public key infrastructure for the quantum era. We demonstrate here a public certification system based on Lizama’s non-invertible key exchange protocol which can be used to ...
