Authentication method of the personal hand-held device system

Abstract

The PHS system authentication method comprises: requesting system to update the authentication code, generates new codes both on system and phone, and recording the request on system; authenticating the mobile phone by system with current used code, if there is update record on the phone, sending update failure message to the phone when the authentication failing in pass, end; if passing authentication, updating current used code as the new code and sending success message to phone; updating current used code as the new one, end. This invention increases user security.

Description

technical field [0001] The present invention relates to a PHS system (Personal Handy Phone System, also known as a wireless local telephone system in China), in particular to an authentication method of the PHS system. Background technique [0002] PHS (Personal Hahdy Phone System, called wireless local telephone system in China) realizes the security of the system by authenticating the mobile phone, and achieves the purpose of not being able to illegally forge numbers and randomly use mobile phones. [0003] The PHS system provides a set of authentication algorithms to verify the legitimacy of users: HLR (HomeLocation Register, home location register) and PS (Personal Station, mobile phone) configure the same authentication code (KEY) before opening, and the system Issue the authentication random number to instruct the mobile phone to authenticate. The mobile phone uses the KEY and the authentication random number to perform authentication calculation according to the authe...

AI Technical Summary

Problems solved by technology

[0006] The machine-card separation technology reduces the possibility of fraud (meaning that the mobile phone user data is copied by others, and other people's numbers can be stolen to make calls, and others pay), but it cannot solve the detection problem after the user is fraudulent. If the user can Quick detection will reduce user losses and improve security

At the same time, since the PHS authentication algorithm is public, the user authentication KEY remains unchanged. Now there are a large number of signaling analyzers, and the user device KEY may be cracked, so it is still impossible to completely prevent user information from being stolen.
