Method, device and system for checking integrality of standby information

Abstract

The invention discloses a method for checking the integrity of object transmitted message, a relative device and a system, wherein the method comprises that A, a receiver receives an object transmitted message, and a plurality of discrete groups transmitted safely, according to the discrete values, obtaining check information, the receiver uses preset sequence rule generates a plurality of sequences via received the object message, and obtaining a plurality of discrete values according to discrete calculation method on the sequences, to obtain check information, B, the receiver judges if the two check information are same, when they are same, the received message is not modified, or else, the message is changed. The invention can protect the transmission integrity of object message, resolve compatibility and cost problems, and improve safety.

Description

technical field [0001] The present invention relates to a technology for integrity protection of message transmission to be transmitted, in particular to a method, device and system for verifying the integrity of message to be transmitted. Background technique [0002] At present, in order to ensure the safe transmission of the message to be transmitted in the network, the sender usually performs hash value calculation on the message to be transmitted, and transmits the obtained hash value together with the message to the receiver, and the receiver then uses the obtained The hash value verifies that the incoming message received is complete and has not been tampered with. The whole process is as follows: firstly, the sender obtains the hash value after performing a hash operation method on the message to be transmitted, and then transmits the obtained hash value and the message to be transmitted to the receiver; after the receiver receives the message to be transmitted, Use...
