A methodology was presented for using running modes, a general method proposed by the authors,to analyzed a key establishment protocol (the Helsinki cryptographic protocol) of ISO/IEC DIS 11770-3.

Formal analysis to revised Helsinki protocol based on strand spaces;

With the improved Helsinki protocol which is applied to negotiate the connection key,a novel secure mechanism is presented.

Based on Promela language and SPIN,the behavior simulation and the attribute verification of Helsinki protocol,and its revised version are made as an example.
