Our research is the adoption of mutual authentication techniques on smart cards for Digital Rights Management (DRM) which applied using network protocol engineering. We adopted engineering from technique owned by Mifare Desfire card. The tests carried out in our are testing security aspects and data confidentiality. test done changing client server master keys that determine success authenticat...

Global mobility networks provide effective global roaming services for personal communication users. Through the universal roaming technology, legitimate mobile users can enjoy the ubiquitous services. Mutual authentication and key agreement between mobile users and roaming servers is the primary security issue of many commercial mobile networks. For personal privacy, it becomes an important is...

Smart grids allow automated meter readings and facilitate two-way communications between the smart meters and utility control centers. As the smart grid becomes more intelligent, it becomes increasingly vulnerable to cyberattacks. Smart grid security mainly focuses on mutual authentication and key management techniques. An impeding factor in grid security is the memory and processing constraint...

Mobile user authentication and key agreement for wireless networks is an important security priority. In recent years, several user authentication and key agreement protocols with smart cards for wireless communications have been proposed. In 2011, Xu et al. proposed an efficient mutual authentication and key agreement protocol with an anonymity property. Although the protocol of Xu et al. has ...

In this paper, the authors present a novel mutual authentication and key agreement protocol based on the Number Theory Research Unit (NTRU) public key cryptography. The symmetric encryption, hash and “challenge-response” techniques were adopted to build their protocol. To implement the mutual authentication and session key agreement, the proposed protocol contains two stages: namely initial pro...

Ad hoc networks are much more vulnerable to security attacks than wired networks or infrastructure-based wireless networks. Secure communication is very important in mobile ad hoc networks. We present detailed security threats against ad hoc routing protocols, specifically the selection of the cluster head (CH) and control cluster head (CCH) using a modification of cluster-based routing ARCH an...

Password-based authentication scheme is one of the efficient authentication mechanics to protect resources from unauthorized access. Chang-Lee, in 2008, proposed a password-based mutual authentication scheme to overcome the security drawbacks of Wu-Chieu’s scheme. In this paper, we have shown that Chang-Lee’s scheme is vulnerable to various attacks known by literatures. Also we proposed an impr...

In 2005, Lee, Kim, and Yoo proposed a nonce-based mutual authentication scheme using smart cards. However, this paper demonstrates that Lee-Kim-Yoo’s scheme is vulnerable to an impersonation attack that the attacker without knowing the remote user’s any secret can masquerade as him by obtaining the valid authentication message from any normal session between the remote user and the system. Our ...

Recently, many identity (ID)-based user authentication and key agreement schemes for mobile client-server environment were proposed. However, these schemes are subjected to an inherent design weakness, namely, the server knows all users’ private keys. Under this problem, these schemes cannot provide insider attack resistance or mutual authentication. Furthermore, some of these schemes cannot si...
