My current research topic focuses on lightweight, efficient and secure design of ECC on FPGAs
Light-weight hardware devices embedded in RFID tags, wireless sensor nodes are just a glimpse of the uprising Internet-of-Things. This recent boom of Internet-of-Things enhances the importance of implementation of asymmetric key cryptography in embedded devices. The front runners of public key cryptography are RSA crypto-system and Elliptic curve cryptography, out of which ECC suits more for the purpose of embedded device security for its wonderful property of providing more security per key bit than its counterpart RSA. For example, 160 bit ECC is comparable to 1024 bit RSA security. Due to the reduced key size, public key protocols like Diffie-Hellman key exchange or digital signature algorithm based on ECC will be more compact, lightweight and less resource hungry compared to RSA based algorithms.
Abstract: The e-commerce has got great development in the past decades and brings great convenience to people. Users can obtain all kinds of services through e-commerce platform with mobile device from anywhere and at anytime. To make it work well, e-commerce platform must be secure and provide privacy preserving. To achieve this goal, Islam et al. proposed a dynamic identity-based remote user mutual authentication scheme with smart card using Elliptic Curve Cryptography(ECC). Islam et al claimed that the security of their scheme was good enough to resist various attacks. However, we demonstrate that their scheme is vulnerable to insider attack and suffers from off-line password guessing attack if smart card is compromised. To overcome the deficiencies, we present an improved scheme over Islam's scheme. The security proof and analysis shows that our scheme can also provide user anonymity and mutual authentication, and the security is enough to against relay attack, impersonation attack, and other common secure attackers. The performance analysis shows that the proposed scheme is more efficient than Islam et al's scheme.
