Abstract

The present invention provides a verification method for data integrity and data source based on a third party without disclosing the verified information. The data to be verified and transmitted is plain text, and the sender does not encrypt it, and the receiver does not need to decrypt the received data; the verification method based on the third party not revealing the data integrity of the verified information and the source key exchange mode, that is, in the simple mode Based on this, the sender and the receiver are further provided with key security transmission to support more confidential communication between them; the verification method based on the data integrity of the verified information and the source confidential communication mode based on the third party does not disclose, that is, in a simple Based on the mode, the transmitted data is verified as ciphertext. The obtained information can be used for identity verification of both the sending and receiving parties, allowing two users who do not know each other's public key to verify the integrity and source of the data sent between them, and can be used to prevent network fraud and establish an authoritative information 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...
