Problems solved by technology

[0004] At present, people usually use the traditional cryptosystem to encrypt the transmitted emails. However, in the traditional cryptosystem algorithm, if the encryption process is known, the decryption process can be introduced. In today's era of rampant network hackers, the traditional cryptosystem can no longer effectively guarantee Security of mail transmission

Embodiment Construction

[0014] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the mail encryption / decryption system of the present invention. The system includes a network 2 for data communication, and a plurality of computers 1 (taking four computers as an example) for communication connection through the network 2 . The network 2 may be the Internet, an intranet or other applicable networks. Described computer 1 can be any applicable data processing equipment, and it is installed with a mail communication software (for example: the Lotus Notes software that U.S. Lotus Company develops), and also is installed with a mail encryption / decryption unit 3 (as figure 2 shown). The computer 1 realizes the mail communication between computers by utilizing the mail communication software. The mail encryption / decryption unit 3 is used for encrypting the mail sent by the computer 1 and decrypting the encrypted mail received by the computer 1 .

Abstract

The invention provides a mail encryption / decryption system comprising a plurality of computers with communication connection mutually. The computer is arranged with mail communication software and a mail encryption / decryption unit which comprises a mail encryption module which is used to set parameters for mail encryption / decryption. The mail communication software is applied to establish a mail text and / or an attachment file to be encrypted. The mail text and / or the attachment file is / are encrypted in accordance with the set mail encryption parameters and the encrypted mail is sent to the computer which receives the mail. The mail encryption / decryption unit also comprises a mail decryption module, which is used to monitor and receive the sent encryption mail. The received encryption mail is decrypted in accordance with the mail decryption parameters and the decrypted mail content is displayed through the mail communication software. The mail encryption / decryption system and the method of the invention avoid the leak of the confidential materials.

Description

technical field [0001] The invention relates to a mail processing system and method, in particular to a mail encryption / decryption system and method. Background technique [0002] Due to various reasons such as the unknowability of the boundary of the computer network, the uncertainty of the routing of the transmitted data, and the sharing of resources, the security of the data transmitted in the computer network is usually not effectively guaranteed. [0003] Many companies use plain text to communicate with the outside world through computer networks, and emails transmitted in plain text are easily intercepted by malicious persons during the transmission process, and the content of the email is easily deciphered, resulting in the leakage of confidential information. vent. Based on the consideration of data security, a reliable and secure transmission mechanism is required during the delivery of emails. [0004] At present, people usually use the traditional cryptosystem ...
