Electronic record validation method and device

Abstract

The invention provides an electronic record validation method and device. The electronic record validation method comprises the steps that a sending end receives files submitted by users and forms electronic files; the sending end seals electronic file number seals on the electronic files to generate electronic records; the sending end makes Hash abstracts for the electronic records to generate first hash values; the sending end uses local private keys to perform hash value signature so as to generate digital signatures; the sending end conducts symmetrical encryption on the electronic records and the digital signatures to generate first ciphertexts; the sending end utilizes a public key of a receiving end to perform asymmetrical encryption on symmetrical encryption keys of the first ciphertexts so as to generate second ciphertexts and sends the first ciphertexts and the second ciphertexts to the receiving end; the receiving end conducts decryption and signature operation verification on the first ciphertexts and the second ciphertexts. The electronic record validation method and device can prevent the electronic records from being counterfeited, tampered and disavowed.

Description

Technical field [0001] The present invention relates to electronic file technology, in particular to an electronic file verification method and device. Background technique [0002] The construction of a guarantee system for the authenticity, integrity, usability and safety of electronic archives is a necessary means to realize effective and safe management of electronic archives. Due to the physical characteristics of electronic file information, it is vulnerable to external forces such as external environment and human operations during its life cycle, such as electronic files being tampered with, data damage in network transmission, imperfect system functions or system failures, etc., the original electronic file The security, integrity, availability, and security are easily affected and destroyed, making it difficult to guarantee the value of electronic files. [0003] At present, there have been many domestic researches on the authenticity, completeness, usability and securit...

AI Technical Summary

Problems solved by technology

Due to the physical characteristics of electronic archive information, it is vulnerable to external environment and human operations during its life cycle, such as tampering of electronic archives, data damage during network transmission, imperfect system functions or system failures, etc. The originality of electronic archives The reliability, integrity, availability and security are easily affected and destroyed, making it difficult to guarantee the credential value of electronic files

[0003] At present, there are many studies on the authenticity, integrity, usability and security of electronic archives in China, but most of the content involved revolves around its necessity, method principles, overall framework and guiding ideology, and there is no specific implementation methods and various indicators, and there are no research results that can guide specific operations
