Trade service platform logon method

Abstract

The invention discloses a trade service platform logon method. The method comprises the following steps: 1) a user registers an account on a trade service platform and associates third-party application systems to be accessed; 2) identity verification information is encrypted, and the trade service platform allocates one identity to each third-party application system and generates a proxy re-encryption secret key; 3) when the user logs on the trade service platform, the encrypted identity identification information is compared with a ciphertext stored in a background server, and when the encrypted identity identification information is same with the ciphertext, logon is successful; and 4) when the user jumps to access the third-party application system, through proxy re-encryption, the third-party application system obtains an identity identification information plaintext of the user, and the user logs in the third-party application system successfully. Based on the proxy re-encryption technology, the plurality of third-party application systems can share identity identification information with the trade service platform, and the user can log onto the plurality of third-party application systems with only one account and passwords being born in mind, thereby realizing an effect of "one login, multiple-party authentication".

Description

technical field [0001] The invention specifically relates to a login method for a trade service platform. Background technique [0002] At present, the development of trade e-commerce has attracted the attention of all walks of life, and government departments are also highly concerned about the future development of my country's trade e-commerce. In order to create an environment conducive to its development, various departments have introduced relevant measures to establish trade service platforms (basic The Internet is a network service platform) to actively guide trade e-commerce. A large number of application systems are deployed inside the trade service platform, such as trading platforms, production enterprise systems, government announcement systems, and logistics tracking systems. These systems are often interrelated in business but the authentication mechanism is independent of each other. With the expansion of the number of systems, repeated logins and a large am...

Problems solved by technology

With the expansion of the number of systems, repeated logins and a large amount of authentication information memory have brought inconvenience to users, weakened user experience, and increased security risks; in addition, redundancy of authentication information increases management costs, making changes difficult. Synchronization is more likely to cause data inconsistency. In addition, the new system authentication module needs to be developed independently, which also increases the difficulty of development.
