Abstract

The invention discloses a mobile terminal safe lock network lock card protecting and unlocking method based on the asymmetrical algorism that includes: the mobile terminal safe lock network lock card protecting method based on the asymmetrical algorism and the mobile terminal safe lock network lock card unlocking method based on the asymmetrical algorism. The invention solves the disadvantages of easy to be decrypted and the complex schedule hard to realize those existed in the present locking network locking card technique.

Description

technical field [0001] The invention relates to an efficient and safe method for preventing illegal cracking and normal use of a mobile phone in a mobile communication terminal, in particular to a method for protecting and unlocking a mobile terminal safety lock network lock card based on an asymmetric algorithm. Background technique [0002] With the global popularity of 3G networks and the intensification of competition among operators, in addition to the traditional sales channels of manufacturers, most mobile phones are customized by operators and sold to end users at low prices with large-scale subsidies. At this time, the network lock and card lock function for a specific operator in the mobile phone is particularly important. The network lock and card lock function of the mobile phone is mainly based on the requirements of the operator. The customized mobile phone can only be used under a specific network with a specific SIM / USIM card, so as to maintain the interests ...
