On a Limitation of BAN Logic
نویسندگان
چکیده
In the past few years a lot of attention has been paid to the use of special logics to analyae cryptographic protocols, foremost among these being the logic of Burrows, Abadi and Needham (the BAN logic). These logics have been successful in finding weaknesses in various examples. In this paper a limitation of the BAN logic is illustrated with two examples. These show that it is easy for the BAN logic to approve protocols that are in practice unsound.

An Alternate Explanation of two BAN-logic "failures"
Boyd and Mao (“On a Limitation of BAN Logic”, in these proceedings) suggest that it is easy to use the authentication logic of Burrows, Abadi and Needham to approve protocols that are in practice unsound, and present two examples. We illustrate that the problem in the first example can be traced to a violation of pre-conditions in the BAN analysis (involving ill-founded trust in a trusted serve...
متن کاملA Fast and Self-Repairing Genetic Programming Designer for Logic Circuits
Usually, important parameters in the design and implementation of combinational logic circuits are the number of gates, transistors, and the levels used in the design of the circuit. In this regard, various evolutionary paradigms with different competency have recently been introduced. However, while being advantageous, evolutionary paradigms also have some limitations including: a) lack of con...
متن کاملUne comparaison entre deux méthodes de preuve de sécurité
In this paper, we compare two methods for security proofs a formal method, and the method by reduction from the complexity theory. A modification of the Otway-Rees protocol is proposed to show out a difference between the two methods : the exchanged key is provably secure in the sense of the BAN logic but it is not when we analyze it by reduction. The difference is due to a limitation of BAN lo...
متن کاملOn BAN Logics for Industrial Security Protocols
This paper reports on two case-studies of applying BAN logic to industrial strength security protocols. These studies demonstrate the flexibility of the BAN language, as it caters for the addition of appropriate constructs and rules. We argue that, although a semantical foundation of the formalism is lacking, BAN logic provides an intuitive and powerful technique for security analysis.
متن کاملA Lightweight Privacy-preserving Authenticated Key Exchange Scheme for Smart Grid Communications
Smart grid concept is introduced to modify the power grid by utilizing new information and communication technology. Smart grid needs live power consumption monitoring to provide required services and for this issue, bi-directional communication is essential. Security and privacy are the most important requirements that should be provided in the communication. Because of the complex design of s...
