In recent years, m-commerce technology has been maturing. Various mobile devices are now designed to help users reach the servers of service providers and to process tasks such as stock trading, product purchasing, product information collecting, and so on. Once the services are only available to the members, authentication is applied to verify the identities of users. However, most current authentication methods used in m-commerce are designed for wired networks and require high computation costs, making them unsuitable for wireless environments.A one-time password authentication scheme that uses lighter computation and considers the limitations of mobile devices is proposed in this paper. Meanwhile, the proposed scheme is free from replay attacks, server spoofing attacks, off-line dictionary attacks, active attacks, and revelation of message contents.
