Abstract

The embodiment of the invention discloses a dynamic password acquisition method and device, a terminal and a storage medium. The method comprises the following steps: initiating an encryption key acquisition request to an NFC (near field communication) encryption card; transmitting an encryption key extraction password input by a user to the NFC encryption card, and extracting the encryption key;generating the dynamic password by utilizing the encryption key, a preset encryption algorithm and the extracted encryption key timestamp. According to the embodiment of the invention, the problem that the encryption key and the encryption algorithm stored in the same medium are easily stolen and unsafe is solved, key and algorithm separation is realized, and the safety of a mobile token of the user is ensured.

Description

technical field

[0001] The embodiment of the present invention relates to a dynamic password technology, in particular to a dynamic password acquisition method, device, terminal and storage medium. Background technique

[0002] The mobile phone token is a mobile terminal software used to generate a dynamic password. The dynamic password generated by its operation is bound to the mobile terminal for identity authentication. It is the mainstream form of dynamic password and identity authentication token in the mobile Internet era. The dynamic password generation mode of the mobile phone token is to use the encryption key, encryption algorithm and time to generate a dynamic password, wherein the "encryption key" and "encryption algorithm" are provided by the mobile terminal program, and the "time" is provided by the network timing service of the mobile terminal .

[0003] Although the "encryption key" is unique, the "encryption key" and "encryption algorithm" have been in a co...
