摘要: IP multimedia subsystem (IMS) is a prominent architectural framework for services delivery in 4G/5G networks. Authentication critical security mechanism which accords authorized users access to these services. As defined by 3rd Generation Partnership Projects (3GPP), IMS- and Key Agreement protocol (IMS-AKA) the official authentication procedure IMS. However, prone different weaknesses both on (disclosure of identities) performances (complexity) aspects. This paper proposes an IMS-AKA+ that addresses effectively user’s identities protection using key-less cryptography. Furthermore, proposed algorithm significantly reduces process complexity due use Elliptic Curve Cryptography (ECC). Simulations were carried out original IMS-AKA protocol. The results showed up 28% time possible, saving 53% storage space occurs with increased less energy.
