Problems solved by technology

[0011] To sum up, the current popular DES, T-DES and other encryption algorithms with less than 128-bit encryption strength can no longer meet the security requirements of the future management platform. How to provide a high-strength, high-performance encryption for the TR069-based terminal management platform channel, so as to prevent the leakage of data packets of important management information and improve the security and performance of the network, which is an urgent problem to be solved at present

Embodiment Construction

[0049] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present invention are illustrated.

[0050] The encryption method of the present invention is based on the SSL security nesting layer suggested in the TR069 protocol, but abandons the 128-bit strength encryption of RSA_3DES_CBC and RSA_RC4 (refer to the PD-128 or TR069 standard of DSL Fourm) recommended in the TR069 protocol. Encryption suite (encryption suite refers to the collection of "public key exchange method", "information encryption algorithm" and "digital signature" based on SSL. For details, please refer to the book "SSL and TLS", or the SSL3.0 standard). The encryption suite of the data encryption module in the SSL protocol is redesigned to implement 256-bit encryption algorithm, key management and exchange, and data integrity and data sender’s reliability verification functions, so that the SSL layer encrypted from th...

Abstract

The invention discloses an encrypting and decrypting method and system in a TR069 comprehensive terminal management platform, including that a transmitting terminal generates a random and calculates random<-1>mod(n); the information m to be transmitted is switched to get the abstract information M is equal to h(m); the abstract information M is encrypted by using a private code da to get the encrypted abstract information Cm and calculate the parameter s that is used for authentication and is equal to k( M plus da ramdom) mod(n); by using a private code d of 256bit and a 256bit grouping length Rijndael algorithm to encrypt the information ( m plus Cm) to get a complete cryptograph C and calculate kP that is equal to (x1, y1), y is equal to x1 mod(n); ( C, y, s) is transmitted to a receiving terminal; wherein, the C is the cryptograph after being encrypted by 256 bits of encrypting intensities and the y and s refer to the authentication information. The invention solves the unreliable problem caused by using an RSA algorithm.

Description

Technical field [0001] The present invention relates to a security encryption technology used in a TR069 remote terminal management platform, in particular to a method and system for encryption and decryption on the TR069 integrated terminal management platform. Background technique [0002] With the popularization of broadband access and the rapid development of multimedia technologies such as Voice over IP (VoIP) and Internet TV (IPTV), more and more WAN terminal devices are introduced into the network. These integrated terminals have complex business configuration requirements, which promotes the development of the WAN terminal management platform based on the TR069 protocol. The management platform has powerful information processing and remote management and configuration terminal capabilities, which can provide users with convenient broadband business services. [0003] The management platform contains a lot of important information about customers, operators, and the platf...
