Welcome to the resource topic for 2008/336

Title:
New attacks on ISO key establishment protocols

Authors: Anish Mathuria, G. Sriram

Abstract:

Cheng and Comley demonstrated type flaw attacks against the key establishment mechanism 12 standardized in ISO/IEC 11770-2:1996. They also proposed enhancements to fix the security flaws in the mechanism. We show that the enhanced version proposed by Cheng and Comley is still vulnerable to type flaw attacks. As well we show that the key establishment mechanism 13 in the above standard is vulnerable to a type flaw attack.
