Method for integrating safety E-mail and Lotus Notes

Abstract

The invention discloses a method for integrating safety E-mail with Lotus Notes. In the process of sending and receiving E-mail, the operating interface is customized and the functions are extended in Lotus Notes by using its safety extension module so as to realize encryption / signature and decryption / validation of signature. The invented method possesses merits of convenient for operation, easy to operate and safety to use.

Description

technical field [0001] The invention relates to a method for integrating secure e-mail and Lotus Notes. Background technique [0002] Secure e-mail mainly uses the digital envelope and digital signature technology based on the public key architecture system. By combining digital envelopes and digital signatures, users can simultaneously obtain confidentiality, integrity and non-repudiation when exchanging data. [0003] Both the digital envelope and the digital signature use the asymmetric encryption algorithm, which uses a pair of keys to complete the encryption and decryption work. In secure e-mail, the symmetric key used for encryption randomly generated in the digital envelope will be encrypted with the recipient's public key, and only the recipient with the corresponding private key can decrypt it, so as to ensure data confidentiality Effect. The digital signature uses the private key of the sender to sign the data, because only the owner of the private key can obtai...

AI Technical Summary

Problems solved by technology

[0013] 4. The recipient cannot confirm the identity of the sender, nor can it prevent the sender from denying the letter afterwards

[0026] 1. Users must leave the use environment of Lotus Notes to manually complete email encryption and decryption, signature and signature verification, which brings great inconvenience to users;

[0027] 2. The content of the text must be written with other editing tools, encrypted and sent to the other party as an attachment, and the powerful editing functions of Lotus Notes cannot be used;

[0028] 3. Symmetric encryption algorithms generally use foreign algorithms, which are limited in strength, so there is a possibility of being cracked at a low cost;

[0029] 4. The symmetric encryption algorithm used is relatively single and fixed, and is not suitable for use in applications with relatively high security requirements or special regulations (such as government departments)
