Abstract

The invention relates to a short message service (SMS) authenticated encryption system and method based on a digital certificate. The SMS authenticated encryption system comprises an SMS authentication center, an authenticated mechanism SMS center and a mobile phone. A digital certificate management service unit of the SMS authentication center provides procedures generated by the unique digital certificate of the authenticated mechanism according to the user identification, thus ensuring the safety of the digital certificate. The digital certificate is used for safety of two-way SMS communication. In the invention, the way that a plurality of different receivers respectively carry out encrypted transmission according to own keys based on the SMS numbers can be realized by only installing an SMS authentication and encryption procedure in the common mobile phone as the SMS authentication and encryption client. The invention can authenticate the received SMS contents, ensure the sent contents not to be falsified and ensure the authenticity of the senders, has good confidentiality, changes less existing SMS systems, occupies less resources, is easy to realize and can be applied to such fields as financial transactions, etc.

Description

technical field

[0001] The invention relates to an authentication and encryption system and an authentication and encryption method for short messages. Background technique

[0002] The application of short message is very popular, but lacks authentication mechanism to short message. In addition, most text messages are sent in clear codes. Although the STK method provides encrypted sending, it can only be encrypted for a single receiver, and it cannot be used to realize multiple different receivers based on their own keys. Encrypted transmission greatly restricts the application of SMS in financial transactions and other fields. Contents of the invention

[0003] The purpose of the present invention is to provide a short message authentication and encryption system based on digital certificates and a corresponding short message authentication and encryption method, which solves the technical problem that the existing short message sending and receiving methods lack an aut...
