Abstract
En 中文
With the rapid development of wireless communication technologies, there is an exponential increase in usage of handheld devices to connect to remote servers. The advancement of communication technology also resulted in increasing number of security threats in public Internet. The resource (processing capacity, memory, battery) constraint nature of hand held devices is a serious bottle neck in implementing computing intensive cryptographic protocols. The current focus of research is to develop light weight authentication protocols. In 2014, Truong et al. proposed a Dynamic Id based remote user authentication scheme for multi-server environment. Truong et al. claimed that their scheme is secure against all major cryptographic attacks and satisfies all the multi-server environment security requirements. Unfortunately, their scheme is vulnerable to all major cryptographic attacks and requires high energy consumption as shown in this paper. As a part of our contribution, we propose a light weight and energy efficient authentication scheme for multi-server scenario that resists all major cryptographic attacks and reduces number of hash operations by 32% and energy consumption by 33%.
