....relies on a change in the original assumptions of the protocol. Whereas Needham and Schroeder assumed that the principals would be honest, Lowe[85] makes the assumption that an intruder could initiate a protocol session, thereby introducing dishonest principals into the system. Tzeng and Hu [158] document two inter protocol interleaving attacks. These attacks use messages from sessions running protocols which are different to the main protocol session. They describe an attack on the Kerberos protocol (Figure 2.10) through the use of a concurrent run of the Otway Rees protocol (Figure ....
....Kerberos protocol using the Otway Rees protocol . Nonces are indistinguishable from timestamps. Messages are indistinguishable from values given as lifetimes (L) An attack on the Kehne Langendorfer Schoenwalder (KLS) protocol, using the Neuman Stubblebine protocol, has also been identified [158]. 2.5.4 Implementation dependent attacks A concrete implementation is produced from the abstract specification of the protocol. The implementation process may introduce insecurities into the protocol, for example, if the method used to create nonces is predictable. A particular example of an ....
