“…The Rabin cryptosystem can be adopted into our proposed scheme because a user should perform only one modular multiplication and some inexpensive operations, such as a hash function, per mutual authentication. In general, a smart card performs up to 3000 modular multiplications per second [24]. Although it is necessary for the server to perform expensive operations in our scheme, it may cause an insignificant decrease in overall system performance because it is assumed that a server is able to maintain sufficient performance.…”

SUMMARYWe demonstrate how Hsiang and Shih's authentication scheme can be compromised and then propose an improved scheme based on the Rabin cryptosystem to overcome its weaknesses. Furthermore, we discuss the reason why we should use an asymmetric encryption algorithm to secure a password-based remote user authentication scheme using smart cards. We formally prove the security of our proposed scheme using the BAN logic.

“…Different from the traditional certificate, the IC is composed of an identity element (still expressed as I) and reconfigurable key data (also expressed as P). P can reconstruct the public key of the identity entity together with the public key of the certificate authority (CA) [13]. Then, the IC could be expressed as a two-tuple (identity element and reconstructed key data) such as (I, P).…”

The ultradense network (UDN) is one of the most promising technologies in the fifth generation (5G) to address the network system capacity issue. It can enhance spatial reuse through the flexible, intensive deployment of small base stations. A universal 5G UDN architecture is necessary to realize the autonomous and dynamic deployment of small base stations. However, the security of the 5G UDN is still in its infancy, and the data communication security among the network entities is facing new challenges. In this paper, we proposed a new security based on implicit certificate (IC) scheme; the scheme solves the security problem among the access points (APs) in a dynamic APs group (APG) and between the AP and user equipment (UE). We present each phase regarding how two network entities obtain the Elliptic Curve Qu-Vanstone (ECQV) implicit certificate scheme, verify each other's identity, and share keys in an UDN. Finally, we extensively analyze our lightweight security communication model in terms of security and performance. The simulation on network bandwidth evaluation is also conducted to prove the efficiency of the solution.the distance between the user equipment (UE) and the network entities and greatly improves the spectrum efficiency. Meanwhile, the UDN has been identified as a constituent of future 5G core technologies by the IMT-2020 expert group [3]. With various small base stations acting as access points (APs), the intersite distance (ISD) decreases as the network entities' density increases. The AP of 5G is different from the traditional macro station. Traditional macro stations are regularly deployed by operators, while AP deployment may be irregular or even deployed by users. Pseudo or malicious AP will threaten 5G system security. What is more, the APs are not just an air network link; they will cooperate with each other to serve user in UDN. In the air transmission of UDN, the unprotected data among the APs is easy to intercept. Therefore, the mutual authentication and the secure data communication among the dense APs, including the keys for the sessions, will face new challenges.As the wireless access network of the 5G, the UDN adopts a different deployment plan that focuses on the new requirement of "network follows user" and supports higher date transmission rates and multiple services.

Certificate authorities (CAs) are the main components of PKI that enable us for providing basic security services in wired networks and Internet. But, we cannot use centralized CAs, in mobile ad hoc networks (MANETs). So, many efforts have been made to adapt CA to the special characteristics of MANETs and new concepts such as distributed CAs (DCAs) have been proposed that distribute the functionality of CA between MANET nodes. In this article, we study various proposed DCA schemes for MANET and then classify these schemes according to their internal structures and techniques. Finally, we propose the characteristics of an ideal DCA system that can be used to verify the completeness of any DCA scheme. This classification and taxonomy identify the weakness and constraints of each scheme, and are very important for designing more secure, scalable, and high performance DCA systems for MANETs and other networks.
