Embodiment 4

[0194] The embodiment of the present invention also provides a method for safely processing short messages, such as Figure 22 As shown, the terminal is an MTC device, and the specific steps are as follows:

[0195] 1201. The terminal receives a short message carrying identification information, a message authentication code and a fresh number;

[0196] The short message contains the identifier of the receiver, the message authentication code MAC and the freshness number Fresh.

[0197] 1202. The terminal calculates a local authentication code according to its preset trigger key, identification information, and fresh data;

[0198] Calculate the local authentication code MAC' according to the preset trigger key Ktrigger, the identifier of the receiver and the freshness number in the received short message;

[0199] Wherein, the local authentication code is calculated using a hash function, and the formula is MAC'=Hash (Ktrigger, Identifier, Fresh).

[0200] 1203. If the message authentic...

Abstract

The invention discloses a security processing method and device for short messages, and relates to the technical field of wireless communication. The method includes: the second device receives the identification information sent by the first device; the second device confirms, according to the identification information, that the recipient is a machine type communication MTC device or confirms that the identification information is not in the authorization list, and sends the information to the The first device sends a rejection indication or a query result; or, if the second device confirms that the recipient is a device other than the MTC device according to the identification information or confirms that the identification information is in the authorization list, it sends The first device sends a confirmation instruction or a query result. The embodiments of the present invention are mainly applied to the security processing process of short messages.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method and device for safe processing of short messages. Background technique [0002] Machine to machine (Machine to Machine, M2M for short) technology is the integration of wireless communication and information technology, which means that there is no need for human intervention to communicate directly between machines. M2M has a rich variety of applications, including the following five applications: automatic meters (water and electricity meters), remote monitoring, industrial security and home automation, payment systems (automated teller machines, support terminals, parking meters, etc.), and remote vehicle control (such as fleet management) , Toll tolls, vehicle recovery, and payment of premiums based on driving conditions, etc.); in-vehicle applications include hands-free, remote communication systems, built-in navigation, emergency calls, remote dia...
