Abstract

The invention discloses a dynamic token initializing method, which comprises the following steps of: receiving and storing first data comprising a sequence number, current time and protection key information and decrypting the protection key information according to a fixed key to obtain a protection key; and receiving second data comprising a checking key ciphertext and a seed dispersion key ciphertext, decrypting the ciphertexts in the second data according to the protection key to obtain a checking key and a seed dispersion key and storing the checking key and the seed dispersion key. The invention also discloses a dynamic token initializing device. According to the invention, due to adoption of the method comprising the steps of receiving and storing the first data comprising the sequence number, the current time and the protection key information, obtaining the protection key according to the protection key information, acquiring the checking key and the seed dispersion key according to the protection key and storing the checking key and the seed dispersion key, the beneficial effect that manual input is not needed when a dynamic token is initialized is achieved, the dynamic token initializing efficiency and safety are improved and the dynamic token initializing process is more convenient.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a method and device for dynamic token initialization. Background technique [0002] A dynamic token is a terminal used to generate a dynamic password. The dynamic password can confirm the legal identity of the user, thereby ensuring the security of the user's business access on the basis of the user logging in with a legal identity. Dynamic password authentication technology is considered to be one of the most effective ways to solve user identity authentication at present, so it is widely used in various information system scenarios such as banking, securities, third-party payment, and large enterprises. [0003] Most of the dynamic tokens in the prior art adopt a symmetric key system, and the encryption and decryption keys of this key system are the same; therefore, the security of the dynamic token depends entirely on the key, and once the key leaks, the ...
