Embodiment

[0028] Such as figure 1 As shown, the basic format of the SMS message transmitted between the SIM card and the server is as follows:

[0029] The message structure is shown in the figure below:

[0030]

[0031] The number of characters that can be transmitted in a text message is fixed. According to the international standard 03.40 protocol, the message header is as follows:

[0032]

[0033]

[0034] According to the current message header, when processing encrypted data transmission, it will definitely exceed the SMS capacity limit. If the number of SMS messages increases, although multiple SMS messages can be processed through the 03.40 protocol, this increases the network load and increases the probability of SMS loss. The transaction success rate is reduced. Therefore, the following message header is proposed, redundant information is removed, the information is simplified as much as possible, and the data is processed in BCD format, making full use of each BI...

Abstract

The invention relates to a teledata transmission content encrypting system and method based on an RFID (radio frequency identification)-SIM (subscriber identity module) card in the technical field of wireless communication. The system comprises a server and an RFID-SIM card, wherein the server contains a server roof certificate and a system user personalized certificate, and the RFID-SIM card contains a service certificate and a personalized certificate. The RFID-SIM card sends short messages with encrypted data to a short message authentication server through a common wireless network provided by an operator, and the short message authentication server also sends the short messages with encrypted data to the RFID-SIM card through the common wireless network provided by the operator in the same way. By utilizing the system and method provided by the invention, the defects of symmetric encryption and asymmetric encryption in the prior art can be overcome, and more comprehensive compressing-encrypting-envelope packet data transmission can be realized.

Description

technical field [0001] The present invention relates to a device and method in the technical field of wireless communication, in particular to a digital envelope-based RFID-SIM card telecommunications data transmission content encryption system and method. Background technique [0002] With the development of society, more and more users have used mobile phones to access the Internet, receive and process related businesses, and many businesses involve sensitive information and key data, and these sensitive information are generally related to users' personal information, and These key data are often the data that users need to confirm and sign in wireless communication transactions. Then, the technical problems of how to better protect the real identities of these users and how to ensure that the business data transmitted on the network are not tampered with are the technical issues that need to be guaranteed and resolved in network transmission. [0003] Asymmetric encrypt...
