Random number used communication safety identification method

Abstract

Provided is a communication security authentication method having the same random number tables between the front and the rear equiopments, wherein the random number table comprises N random number groups, and each group has three random numbers, including the following steps: Synchronize the current pointer of the random number tables at the front and rear ends, and the current pointer is equal to the larger one at the front and rear ends in the next authentication; Transmit the first random number of the m-th random number group at the front end to the rear end; Compare the first random number of the corresponding number group at the rear end wire the first random number at the front end; if they are equal, update the pointer number of the rear end to m+1 in the next authentication.

Description

(1) Technical field

[0001] The invention relates to a communication security authentication method, in particular to a communication security authentication method using random numbers. (2) Background technology

[0002] With the development of modern technology, security certification has penetrated into various fields. For example, commercial activities such as e-commerce and automatic deposit and withdrawal, enterprise management such as security access control and management authority, all of which require security authentication. Currently, the most commonly used authentication method is encryption authentication. In this authentication process, both the encryption and decryption parties have a secret key, the so-called encryption algorithm. The information sender encrypts the information with an encryption key according to the encryption algorithm, and then sends the encrypted information to the receiver. The receiver uses the decryption key to decrypt the received ...
