It was first used by Michael Merritt , who showed that an algebraic model can be used to analyze cryptographic protocols. Other approaches are in [473,1508,1530,1531,1532,1510,1612].

----------- The Navy Research Laboratory’s (NRL) Protocol Analyzer is probably the most successful application of these techniques [1512,823,1046,1513]; it has been used to discover both new and known flaws in a variety of protocols [1044,1045,1047]. The Protocol Analyzer defines the following actions: — Accept (Bob, Alice, M, N). (Bob accepts the message M as from Alice during Bob’s local round N.) — Learn (Eve, M). (Eve learns M.) — Send (Alice, Bob, Q, M). (Alice sends M to Bob in response toquery, Q.) — Request (Bob, Alice, Q, N). (Bob sends Q to Alice during Bob’s local round N.) From these actions, requirements can be specified. For example: — If Bob accepted message M from Alice at some point in the past, then Eve did not learn M at some point in the past. — If Bob accepted message M from Alice in Bob’s local round N, then Alice sent M to Bob as a response to a query in Bob’s local round N. To use the NRL Protocol Analyzer, a protocol must be specified using the previous constructs. Then, there are four phases of analysis: defining transition rul...
