Rapid development of wireless networks brings about many security problems in Portable Communication Systems (PCS), which can provide mobile users with an opportunity to enjoy global roaming services. In this regard, designing a secure user authentication scheme, especially for recognizing legal roaming users is indeed a challenging task. Recently, C-C Lee et al. proposed such scheme, which is claimed to be an improvement of T. F. Lee et al.’s protocol. However, in this article, we reveal that the scheme proposed by C-C Lee et al. still suffers from certain weaknesses like vulnerable to DoS attack, no perfect forward secrecy, loss of Untraceability, etc. Hence, C-C Lee et al.’s delegation-based protocol cannot guarantee secure communication for PCS environment.DOI: http://dx.doi.org/10.5755/j01.itc.44.3.9777

Ordinary Citizens

Today millions of ordinary citizens are using networks for banking, shopping and filing their tax return. Network security has become a massive problem. All this requires network to identify its legal users for providing services. An authentication protocol used is Kerberos which uses strong secret key for user authentication but it is vulnerable in case of weak passwords. Authentication  & key distribution protocols requires sharing secret key(s) with a view that only the concerned users know to derive the information from it. These protocols are vulnerable to key guessing attacks. Another important consideration is perfect forward secrecy in which our proposed scheme cover cases with application servers, authentication servers or clients key are revealed & their combination. In this paper our proposed scheme deal with key guessing attacks, perfect forward secrecy and protocols for few combinations of keys. All these protocols are based on the fact that the keys are weak & can be exploited easily.

Perfect Forward Secrecy

Unmanned Aerial Vehicle (UAV) plays a paramount role in various fields, such as military, aerospace, reconnaissance, agriculture, and many more. The development and implementation of these devices have become vital in terms of usability and reachability. Unfortunately, as they become widespread and their demand grows, they are becoming more and more vulnerable to several security attacks, including, but not limited to, jamming, information leakage, and spoofing. In order to cope with such attacks and security threats, a proper design of robust security protocols is indispensable. Although several pieces of research have been carried out with this regard, there are still research gaps, particularly concerning UAV-to-UAV secure communication, support for perfect forward secrecy, and provision of non-repudiation. Especially in a military scenario, it is essential to solve these gaps. In this paper, we studied the security prerequisites of the UAV communication protocol, specifically in the military setting. More importantly, a security protocol (with two sub-protocols), that serves in securing the communication between UAVs, and between a UAV and a Ground Control Station, is proposed. This protocol, apart from the common security requirements, achieves perfect forward secrecy and non-repudiation, which are essential to a secure military communication. The proposed protocol is formally and thoroughly verified by using the BAN-logic (Burrow-Abadi-Needham logic) and Scyther tool, followed by performance evaluation and implementation of the protocol on a real UAV. From the security and performance evaluation, it is indicated that the proposed protocol is superior compared to other related protocols while meeting confidentiality, integrity, mutual authentication, non-repudiation, perfect forward secrecy, perfect backward secrecy, response to DoS (Denial of Service) attacks, man-in-the-middle protection, and D2D (Drone-to-Drone) security.

Group Key Establishment

In this paper, we analyze the security of a group key establishment scheme proposed by López-Ramos et al. This proposal aims at allowing a group of users to agree on a common key. We present several attacks against the security of the proposed protocol. In particular, an active attack is presented, and it is also proved that the protocol does not provide forward secrecy.
