Abstract

The invention discloses an identity authentication method. Firstly, a portable storage device loads a session key generation mechanism identical to itself and a decrypting mechanism corresponding to an own encrypting mechanism onto a terminal; then, the portable storage device uses an own session key to encrypt a self-produced session ticket; the terminal generates the session key according to the session key generation mechanism identical to the portable storage device, ensures that the own session key decrypts the encrypted session ticket from the portable storage device and returns the session ticket obtained after the decryption to the portable storage device; subsequently, the portable storage device can compare the received session ticket with the session ticket produced by itself, so as to realize the identity authentication. At the same time, the invention also discloses an identity authentication system. The method and the system can improve the safety of the identity authentication between the terminal and the portable storage device.

Description

technical field

[0001] The invention relates to the field of information security, in particular to an identity authentication method and system. Background technique

[0002] When a terminal (such as a PC, mobile phone, etc.) accesses a portable storage device (such as a smart card, a memory card, etc.), the portable storage device needs to perform identity authentication on the accessed terminal, figure 1 It is a flowchart of an identity authentication method in the prior art. like figure 1 As shown, the method for identity authentication in the prior art includes the following steps:

[0003] Step 101, when a terminal detects a portable storage device, it powers on the portable storage device, and the portable storage device sends an identity authentication request to a terminal requesting access.

[0004] Step 102: After receiving the identity authentication request sent by the portable storage device, the terminal prompts the user to input a personal identification n...
