Abstract

The invention provides a method and a device for constructing a message hash chain, which can form a hash chain about a message sequence by using a hash value of a transmitted message through iterative hash. The integrity, authenticity and synchronism of a message sequence can be ensured by both communication parties through a hash chain, so that the security of message transmission is greatly improved; when data signature authentication is carried out, two communication parties only need to carry out signature authentication according to data messages at certain intervals, signature authentication does not need to be carried out on each data message, the integrity and non-repudiation of a plurality of messages can be ensured, the overhead of signature authentication is reduced, and thus the message transmission efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for constructing 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 a method and device for constructing 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 present inventi...
