Provably Secure ECC-Based Device Access Control and Key Agreement Protocol for IoT Environment

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...

A new provably secure authentication and key agreement protocol for SIP using ECC

SIP is playing a key role in the IP based services and has been chosen as the protocol for multimedia application in 3G mobile networks by the Third-Generation Partnership Project. The authentication mechanism proposed in SIP specification is HTTP digest based authentication, which allows malicious parties to impersonate other parties or to charge calls to other parties, furthermore, other secu...

Provably-Secure Enhancement on 3GPP Authentication and Key Agreement Protocol

An Efficient ECC-based Authentication and Key Agreement Protocol

Public-key cryptography is commonly used to authenticate communicating entities in some networks. One of the key tools in this way is to use the elliptic curves cryptography (ECC) which is relatively lightweight due to its shorter key size compared to the conventional River-Shamir-Adleman (RSA) method. This paper is proposing an efficient protocol by analysing two variants of ECC-based wireless...
