Therefore there is a need of a secure protocol for performing B2C type of e-commerce transactions. The B2C type the main participating entities are customers, website and merchant. In this paper the communication between the website and merchant is represented by WM protocol. The design of WM protocol must consider several issues like problem definition, services, environment, vocabulary and message formats. The verification of WM protocol is also performed with respect to the protocol procedure rules based on linear temporal logic. The procedure rules related to the protocol is specified in process meta language. The verification is performed by using SPIN model checker and corresponding results are reported
