An Improved Certificateless Authentication Key Agreement Protocol

An efficient certificateless two-party authenticated key agreement protocol

Due to avoiding the key escrow problem in the identity-based cryptosystem, certificateless public key cryptosystem (CLPKC) has received a significant attention. As an important part of the CLPKC, the certificateless authenticated key agreement (CLAKA) protocol also received considerable attention. Most CLAKA protocols are built from bilinear mappings on elliptic curves which need costly operati...

An Improved Authenticated Multiple-key Agreement Protocol

Simulatable certificateless two-party authenticated key agreement protocol

Key agreement (KA) allows two or more users to negotiate a secret session key among them over an open network. Authenticated key agreement (AKA) is a KA protocol enhanced to prevent active attacks. AKA can be achieved using a public key infrastructure (PKI) or identity-based cryptography. However, the former suffers from a heavy certificate management burden while the latter is subject to the s...

A Certificateless Multiple-key Agreement Protocol Based on Bilinear Pairings

Certificateless cryptosystems were proposed by Al-Riyami and Paterson in 2003 [1] to solve problems of public key cryptosystems based on PKI and based on identity. Up to now, various types of certificateless cryptographic primitives as encryption functions, signature schemes, key agreement protocols and etc, have been designed. But to the best of our knowledge, multiple-key agreement protocols ...

Ironwood Meta Key Agreement and Authentication Protocol

Number theoretic public key solutions are subject to various quantum attacks making them less attractive for longer term use. Certain group theoretic constructs show promise in providing quantum-resistant cryptographic primitives. We introduce a new protocol called a Meta Key Agreement and Authentication Protocol (MKAAP) that has some characteristics of a public key solution and some of a share...
