Problems solved by technology

[0002] In the current network data transmission process, the message authentication code can be used to verify the integrity of the message, and the shared key method can be used to improve the security of data transmission, but the non-repudiation of the message cannot be guaranteed.
The method of using public and private keys to sign and authenticate the message can ensure the non-repudiation of the message, but the overhead of this method is large, resulting in low performance of data transmission

Abstract

The invention provides an authentication method and system based on a message hash chain, and the method and system can enable the hash value of a transmitted message to form a hash chain related to a message sequence through iterative hash. The integrity, authenticity and synchronism of the message sequence can be ensured by both communication parties through the Hash chain, so that the security of message transmission is greatly improved. During data signature authentication, two communication parties only need to carry out signature authentication according to data messages at certain intervals, or actively require signature authentication after verification fails, or carry out authentication after signature in the first message or the last message, and signature authentication does not need to be carried out on each data message; therefore, the integrity and non-repudiation of a plurality of messages can be ensured, the overhead of signature authentication is reduced, and the message transmission efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to an authentication method and system based on message hash chains. Background technique [0002] In the current network data transmission process, the integrity of the message can be verified by the message authentication code, and the security of data transmission can be improved by using the shared key method, but the non-repudiation of the message cannot be guaranteed. The method of using the public and private keys to sign and authenticate the message can ensure the non-repudiation of the message, but the overhead of this method is large, resulting in low performance of data transmission. Contents of the invention [0003] The present invention aims to provide an authentication method and system based on a message hash chain that overcomes the above problems or at least partially solves the above problems. [0004] In order to achieve the above object, the technical solution of the...
