Algebraic generalization of Diffie–Hellman key exchange [PDF]
The Diffie–Hellman key exchange scheme is one of the earliest and most widely used public-key primitives. Its underlying algebraic structure is a cyclic group and its security is based on the discrete logarithm problem (DLP).

The Group Diffie-Hellman Problems [PDF]
In this paper we study generalizations of the Diffie-Hellman problems recently used to construct cryptographic schemes for practical purposes. The Group Computational and the Group Decisional Diffie-Hellman assumptions not only enable one to construct ...

Rate-1 Trapdoor Functions from the Diffie-Hellman Problem [PDF]
Trapdoor functions (TDFs) are one of the fundamental building blocks in cryptography. Studying the underlying assumptions and the efficiency of the resulting instantiations is therefore of both theoretical and practical interest.

Identity-based Encryption from the Diffie-Hellman Assumption
We provide the first constructions of identity-based encryption and hierarchical identity-based encryption based on the hardness of the (Computational) Diffie-Hellman Problem (without use of groups with pairings) or Factoring.

Dynamic Group Diffie-Hellman Key Exchange under Standard Assumptions [PDF]
. Authenticated Diffie-Hellman key exchange allows two principals communicating over a public network, and each holding public/private keys, to agree on a shared secret value.

Variants of the Diffie-Hellman Problem
Many variations of the Diffie-Hellman problem exist that can be shown to be equivalent to one another. We consider following variations of Diffie-Hellman problem: square computational and Square decisional Diffie-Hellman problem, inverse computational ...

Secure communication mechanism for VSN based on certificateless signcryption
To solve the communication security problems of vehicular social network (VSN), an efficient certificateless signcryption scheme was proposed.The proposed scheme was proven secure in the random oracle model based on the computational Diffie-Hellman ...

Privacy-Aware Secure Anonymous Communication Protocol in CPSS Cloud Computing
Cloud computing has emerged as a promising paradigm for the Internet of Things (IoT) and Cyber-Physical-Social Systems (CPSS). However, the problem of how to ensure the security of data transmission and data storage in CPSS is a key issue to address.

A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication
ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.
