Abstract: Smart card is an outlook technology and has paid a great important role in identity authentication application. However, as its limitation of the memory size and processing power, smart card's security and efficiency have become the most imperative concerns. In this paper, based on elliptic curve cryptosystem, an efficient and provably secure authentication scheme on smart cards is proposed
