The invention provides an authentication method, an authentication system and an authentication device. The authentication method comprises the following steps that: a dynamic password generation device generates a first challenge value; an authentication server receives the first challenge value; the authentication server calculates a first one-time password according to the first challenge value; the dynamic password generation device receives the first one-time password; the dynamic password generation device resolves a second challenge value according to the first one-time password; and the dynamic password generation device judges whether the authentication server is legal by comparing the first challenge value with the second challenge value. According to the authentication method, whether the authentication server is legal is judged by checking whether the one-time password generated by the server comprises the challenge value generated by the dynamic password generation device; and therefore the security of network electronic transaction is improved.
Description
technical field [0001] The present invention relates to the field of information security, in particular to an authentication method, system and device. Background technique [0002] Nowadays, with the rapid development of the Internet and financial informatization, online banking is popularized rapidly, but the authentication method using static passwords in online electronic transactions has certain security defects. Most of them use dynamic password tokens or dynamic password cards to strengthen the security of network identity authentication. [0003] The feature of the dynamic password technology is that the user enters the dynamic password according to the displayed number of the dynamic password token provided by the service provider. According to the dynamic password technology, according to the different password generation methods, it can be divided into time-based and challenge / response-based dynamic password technologies. The implementation method of the time-b...
