Dynamic password token based on SM3 algorithm

With the development of Internet technology, dynamic password token have won more and more favor in the field of identity authentication with the good security and ease of operation. Nowadays, foreign's SHA series of algorithms of dynamic password productsare widely using in our country, which have caused a potential threaten for the localization of information security. To realize the research and development of the independent technology products based state-owned cipher algorithm will make encryption products be better safeguarded. In this paper, I select the dynamic password authentication technology based on time synchronization, and a dynamic password is designed by using the state-owned SM3 algorithm Experimental result show that this method has high security and value.
