Anonymous and expeditious mobile user authentication scheme for GLOMONET environments

Abstract

Summary The Global Mobility Network (GLOMONET) is rapidly becoming important as well as a popular feature in today's high‐performance network. The legal mobile users enjoy life using the ubiquitous services via GLOMONET. However, because of the broadcast nature of the wireless channel, providing user authentication along with the privacy and anonymity of the users in GLOMONET is indeed a challenging task. In this article, we come up with a secure and expeditious mobile communication environment using symmetric key cryptosystem to ensure mobile users' anonymity and privacy against eavesdroppers and backward/forward secrecy of the session key. Our scheme can also protect numerous security threats, like man‐in‐the‐middle attack, known session key attack, lost smartcard attack, and forgery attack. Furthermore, we put forward a new technique named as “friendly foreign agent policy,” where many foreign agents can make different groups among themselves and perform important responsibilities to authenticate a legitimate mobile user without interfering his or her home agent even though the mobile user moves to a new location, covered by a new foreign agent (belongs to the same group). Security and performance analyses show that the proposed scheme is secure and more efficient as compared with other competitive schemes for GLOMONET environments.

LCDMA: Lightweight Cross-Domain Mutual Identity Authentication Scheme for Internet of Things

“…It can be seen that the aforementioned schemes all have security vulnerabilities. Gope et al [16] proposed an authentication scheme based on symmetric keys. However, Roy and Bhattacharya [21] found various defects in the scheme of [16], including the vulnerabilities to insider attacks, offline password guessing attacks, session key leak, unauthenticated login stage, imperfect forward secrecy and inappropriate mutual authentication as well as having high database maintenance costs and synchronization problem.…”

“…The emergence of identity authentication schemes based on symmetric polynomial represent a breakthrough in the field of IoT authentication. However, the cross-domain access process of the existing symmetric polynomial-based authentication schemes [15], [16], [17], [18] is complicated. The trusted center also cannot provide trusted traceability services to locate illegal acts, and may not be able to eliminating malicious users.…”

Anonymous Lightweight and Secure Authentication Schemefor IoT-Enabled Smart Homes

“…Unfortunately, smart home devices and appliances are not suitable for public key crypto-systems due to their limited resources for processing and communication costs [17]. However, various secure and compact schemes based on authentication and key agreement protocols can be used to ensure the security and privacy of authorized users in IoTenabled smart homes [18], [19]. As shown in Figure 1, the proposed architecture consists of a gateway and many Wi-Fi-connected IoT appliances, providing remote access and control of the smart home network to users [20].…”

SKIA-SH: A Symmetric Key-Based Improved Lightweight Authentication Scheme for Smart Homes

“…Such security and privacy issues can enable an entity with malicious intentions also called as an attacker to expose user-related sensitive data including the daily routines, habits, and so on, and this information can be used with wicked intentions. In addition, the SDs are lightweight devices, and deploying public key-based infrastructure (PKI) is not a viable solution for the SH environments as PKI can pose high computation and communication costs on the low powered SDs [3][4][5].…”
