IBE (Internet Booking Engine) data encryption system based on medium digital certificate

Abstract

The invention relates to an IBE (Internet Booking Engine) data encryption system based on a medium digital certificate, and comprises four components: an IBE CSP (Cryptographic Service Provider), an IBE key management client, an IBE key server and an IBE client installing software, wherein the IBE CSP is the core and key of the IBE data encryption system. The IBE data encryption system is used for enabling the system and the application which do not support an IBE encryption process to utilize the IBE process to encrypt and decrypt. In the IBE data encryption system, the medium digital certificate is taken as a bridge, an asymmetric key algorithm which is supported by RSA (Rivest Shamir Adleman), ECC (Elliptic Curves Cryptography) or other X509 certificate is provided by a register, but actually a Windows CSP of the IBE algorithm is realized, the data encryption and decryption operations based on the RSA, ECC or other asymmetric key algorithms are automatically converted into the corresponding data encryption and decryption operations based on the IBE algorithm.

Description

technical field [0001] The invention belongs to the technical field of data encryption, and is an IBE (Identity Based Encryption: identity-based encryption) data encryption system based on a media digital certificate, especially enabling systems and applications that do not support the IBE encryption technology to use the IBE technology for data encryption. Encryption and decryption. Background technique [0002] In the public key encryption system, the public key (Public Key) is used for data encryption and digital signature verification, and the private key (Private Key) is used for data decryption and digital signature. In order to improve the efficiency of data encryption and decryption, in the practical application of using public key encryption technology, when one party sends encryption to the other party, the sender usually first encrypts the data with a randomly generated symmetric key, and then uses the receiving key to encrypt the data. The party's public key enc...

AI Technical Summary

Problems solved by technology

[0005] IBE encryption has its unique advantages, it brings convenience to data transmission encryption, but there is also a prominent problem in the practical application of IBE technology: most of the current operating systems (such as Windows) and application software (such as Outlook) do not support IBE encryption technology, on the contrary, most current operating systems and applications support RSA public key algorithm and RSA digital certificate
