A Study on the Hybrid Encryption Technology in the Security Transmission of Electronic Documents

Abstract

Although electronic documents have been greatly improved in the transferring speed and processing speed, it would also result that electronic documents information is disclosed, counterfeited, tampered, repudiated and so on. In order to solve the above problems and greatly improve the security of electronic documents, this paper researches a hybrid encryption technology, that is, encryption technology, digital digest, digital authentication and digital signature. Encryption technology is to ensure the confidentiality of information, digital digest to ensure the integrity of information, while digital authentication and digital signature technology can be certified to protect the Authentication identity, non-repudiation and non-counterfeit. By using of hybrid encryption technology, that is, the above four kinds technology of integration application, the security of electronic documents will be greatly improved.
