Supersingular Isogeny Diffie–Hellman Authenticated Key Exchange [PDF]

, 2018
We propose two authenticated key exchange protocols from supersingular isogenies. Our protocols are the first post-quantum one-round Diffie-Hellman type authenticated key exchange ones in the following points: one is secure under the quantum random ...

Short Exponent Diffie-Hellman Problems [PDF]

, 2004
In this paper, we study short exponent Diffie-Hellman problems, where significantly many lower bits are zeros in the exponent. We first prove that the decisional version of this problem is as hard as two well known hard problems, the standard decisional Diffie-Hellman problem (DDH) and the short exponent discrete logarithm problem.

Reinventing EDHOC for the Post-Quantum Era

IEEE Access
Several lightweight protocols are being developed to secure communication in resource-constrained environments. Ephemeral Diffie-Hellman over COSE (EDHOC) plays a key role in this lightweight protocol family by managing the key establishment process ...

Searchable Attribute-Based Signcryption Scheme for Electronic Personal Health Record

IEEE Access, 2018
Considering the scenario of an electronic personal health record system, we put forward a new cryptographic concept called searchable attribute-based signcryption, which can support fine-grained access control, data privacy, data authenticity, and data ...

Provable Secure ID-based Proactive Threshold Signature in the Standard Model

工程科学与技术, 2010
:At present, the security of the identity based proactive threshold signature schemes was almost proved in the random oracle model, and the threshold values of these schemes were almost changeless.

Key exchange protocol Diffie-Hellman

, 2016
U završnom radu je opisan Diffie-Hellman protokol rukovanja ključevima, njegov nastanak, korištenje u praksi, te dvije moguće implementacije. Opisane su i mane Diffie-Hellman protokola, te je spomenuto kako ih otkloniti.
