Several years ago, handheld devices were regarded luxuries. But they are almost
taking the place of the traditional phones. It is because of the speedy development of
mobile and wireless communication technologies. Nowadays, the mobile station plays an
important role in most people?s daily life. Furthermore, the explosion of the Internet has
led to an electronic commerce environment such that people can conduct most transactions
electronically. To improve the convenience and portability of electronic commerce,
the mobile commerce system is proposed. In 2003, Lam et al. proposed a lightweight security
mechanism for mobile commerce. Unfortunately, we find that there exists a security
weakness in their method. Hence, we provide improvements on their proposed authentication
protocol to make it secure. Besides, we propose a new authentication protocol for
the mobile commerce transactions without adopting the public key cryptosystem.
