A Critical Analysis and Improvement of AACS Drive-Host Authentication
نویسندگان
چکیده
This paper presents a critical analysis of the AACS drive-host authentication scheme. A few weaknesses are identified which could lead to various attacks on the scheme. In particular, we observe that the scheme is susceptible to unknown key-share and man-in-the-middle attacks. Modifications of the scheme are suggested in order to provide better security. A proof of security of the modified scheme is also presented. The modified scheme achieves better efficiency than the original scheme.

Using SPIN to Detect Vulnerabilities in the AACS Drive-Host Authentication Protocol
In this paper, we use SPIN, a model checker for LTL, to detect vulnerabilities in the AACS drive-host authentication protocol. Before the detection, we propose a variant of the Dolev-Yao attacker model [4] and incorporate the synthesis and analysis rules [7] to formalize the protocol and the intruder capabilities. During the detection, we check the authenticity of the protocol and identify a fe...

متن کاملA TESLA-based mutual authentication protocol for GSM networks
The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...
