ETP-AKEP: enhanced three-party authenticated key exchange protocols for data integrity in cloud environments

Abstract

With key exchange protocols, a secure session key is generated between two remote users, and servers and exchanged between them. It is generally used to prevent unauthorised users from gaining access to sensitive data. This article presents an enhanced three-party authenticated key exchange protocols (ETP-AKE) protocol that does not depend on symmetric key encryption and instead uses asymmetric key encryption. A key component of the proposed ETP-AKE protocol is using elliptic curve encryption in conjunction with a one-way hash function. Its integrity certification was confirmed via the usage of the AVISPA tool package. Our proposed protocol is intended to protect against various security threats, including the man-in-the-middle assault, the parallel attack, and the key-compromise attack, among others.
