Satellite mobile communication terminal user identification and authentication function test method

Abstract

The invention discloses a satellite mobile communication terminal user identification and authentication function test method. The method comprises the following steps: a pulse digital signal is sent to an UIM card by a DSP in a timing manner; the received pulse digital signal is detected by the UIM card, if a pulse digital signal sequence code error occurs, then reset is performed directly, and connection is reestablished at the interval of a set time; the public key of an authorized user is saved by the UIM card, and the private key of the authorized user is saved by the DSP; after the password of the authorized user is received by the DSP, decryption is performed on the private key, and then signing is performed on an opening instruction with the private key and the signed data is sent to the UIM card; and after the data is received by the UIM card, authentication is performed on the opening instruction with the public key, and only after the authentication is successful, the information data can be read and a corresponding operation is entered. The method of the invention can be used to reliably verify and ensure the satellite mobile communication terminal user identification and authentication function and effectively prevent the stealing and damage of illegal users on wireless channels and information thereof so as to ensure the safety of information transmission.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a test method for user identification and authentication functions of a satellite mobile communication terminal. Background technique [0002] At present, satellite modulators are bound by hardware conditions and fixed configuration software. The encoding method, specification, and modulation method are fixed after delivery to users. In the future, a new encoding method, specification, and modulation method will need to be redeveloped. , the production cycle is relatively long, the versatility and portability are poor, the software cannot be upgraded online, and the future needs of users cannot be met. Therefore, it is necessary to design a general-purpose hardware platform first, and then realize arbitrary variable modulators such as coding methods, specifications, and modulation methods under the premise of the same hardware platform, so as to break through the bottleneck...
