1996-11-28 paulson 1996-11-28 Weaking of injectivity assumptions for newK and newN: they are no longer assumed injective over all traces, merely over the length of a trace
1996-10-09 paulson 1996-10-09 New version of axiom sees1_Says: Previously it only allowed the SENDER to see the content of messages... Now instead the RECIPIENT sees the messages. This change had no effect on subsequent proofs because protocol rules refer specifically to the relevant messages sent to an agent.
