Embodiment Construction

[0026] Further details will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0027] With the development of technology, various intelligent circuit modules can be added to the mobile terminal, especially the SIM card (subscriber identity model) in the ordinary mobile phone (hereinafter referred to as "mobile phone") through various methods, so that in addition to the basic In addition to the SIM card function, there are other more applicable extended functions. By adding a bridging smart card between the mobile phone card slot and the SIM card, the mobile phone can have functions such as micropayment, time attendance, and short message extension without changing the mobile phone and SIM card. The smart card involved in the method of the present invention is a smart card with these functions. The smart card is connected to the mobile phone and the SIM card through the interface at the same time, and it does not affect the normal use of t...

Abstract

The invention relates to a method for transmitting an encrypted short message, which makes use of the bridging technology of a smart card (102) for encrypting short message independent of an SIM card (103) to protect the content of the short message. By adopting the method for transmitting the encrypted short message, the encrypted short message can be transmitted among appointed users adopting the method. The method comprises two steps of sending and receiving the short message. The step of sending the short message comprises the steps of formulating the content of the short message; encrypting the content of the short message in the smart card; adding non-regular character sequences prior to the encrypted short message; establishing complete short message data; sending the encrypted short message to a target user. The step of receiving the short message comprises the steps as follows: a mobile terminal writes commands and sends the commands to the SIM card after the mobile terminal receives the short message; the smart card analyzes the identification of the short message, and if the short message is an encrypted short message through analysis, the short message shall be stored in the smart card after the short message is decrypted. The method of the invention has the technical effect of ensuring the safe transmission of the short message.

Description

technical field [0001] The invention relates to a method for transmitting short messages between mobile user equipments, in particular to a method for encrypting the transmitted short messages. Background technique [0002] With the development of technology and the popularity of mobile terminal applications, the application of short message functions is becoming more and more extensive. At present, many SIM (Subscriber Identity Module) ie Subscriber Identity Cards with STK (SIM Tool Kit, Subscriber Identity Application Development Tool) have the function of sending short messages through proactive commands of the SIM card. STK can be understood as a set of commands for developing value-added services, a small programming language that allows SIM cards based on smart cards to run their own application software. STK technology is mainly used in mobile banking, stock trading, foreign exchange trading and financial secretary and other fields. New mobile services such as "mobi...
