Abstract

The invention discloses a mobile end which comprises a factor capturing device which captures the factor from the user identifying module card of the mobile end, an end key storage which stores a group of optional key, and an end encipher which uses one key of the end key storage to do the encipher and generate the end cryptogram. It also discloses a user identifying module card used in mobile end which comprises: a factor generator which generates the factors and transmits them to the mobile end, a key storage, encipher and a cryptogram tester which compares the generated cryptogram with the end cryptogram. It also discloses a testing method used in the mobile end and the user identifying nodule card.

Description

technical field [0001] The present invention relates to a mobile terminal for a mobile public phone, a subscriber identity module card for the mobile terminal and a verification method for them. Background technique [0002] With the development of wireless communication technology, wireless products are widely used in public communication field, and mobile public phones are widely promoted by operators. A mobile phone is a mobile phone that looks exactly like a fixed line. It does not require telephone lines, is not subject to geographical restrictions, and is cheaper than ordinary mobile phones. Therefore, it is favored by many users. However, the security performance of mobile public phones was relatively low before, and it was very common for the Subscriber Identity Module (SIM) card to be taken out and stolen in mobile phones, which seriously affected the development of this service and the revenue of ordinary mobile phone voice services.
