Third-party-based verified information non-leakage data integrity and source verification method

Abstract

The invention provides a third-party-based verified information non-leakage data integrity and data source verification method which comprises a third-party-based verified information non-leakage dataintegrity and source verification method in a simple mode, a third-party-based verified information non-leakage data integrity and source verification method in a key exchange mode and a third-party-based verified information non-leakage data integrity and source verification method in a secure communication mode, wherein the third-party-based verified information non-leakage data integrity and source verification method in the simple mode is used for a case that verified and transmitted data is a cleartext, a sender does not encrypt the data and a receiver also does not need to decrypt the received data; according to the third-party-based verified information non-leakage data integrity and source verification method in the key exchange mode, on the basis of the simple mode, key securitytransmission is further provided for the sender and the receiver so as to support more secure communication between the sender and the receiver; and according to the third-party-based verified information non-leakage data integrity and source verification method in the secure communication mode, on the basis of the simple mode, the verified and transmitted data is a ciphertext. Acquired information can be used for identity verification of both the sender and the receiver, and two users who do not know public keys of opposite parties are allowed to verify an integrity and a source of data sentbetween the users, and the third-party-based verified information non-leakage data integrity and source verification method can be used for defending internet frauds and establishing an authoritativeinformation release and verification platform.

Description

technical field [0001] The present invention relates to a verification method, in particular to a verification method based on data integrity and source of the verified information not disclosed by a third party. Background technique [0002] In today's society, a large amount of information is transmitted through communication networks such as the Internet. The confirmation of the data source (that is, the source of data transmission) and the verification of whether the data has been tampered with during transmission (that is, the integrity of the data) are important aspects of data security, and its correctness will further affect the security of applications. sex. At present, there are many criminal activities such as Internet fraud that take advantage of the defects in data integrity and source verification, for example, posing as state agency staff or individuals to publish false information or even conduct financial fraud on the Internet. [0003] In fact, the confir...

Problems solved by technology

[0004] A common problem with the above methods is that the recipient needs to know the sender's public key in time to perform digital signature verification, but this is often difficult, especially for digital transmissions between general users, especially those who do not frequently carry out data between interacting users
