METHOD FOR STORING KEY PARAMETERS AND TERMINAL DEVICE

摘要

The present invention provides a method for storing key parameters and a terminal device. The method includes the following steps of: processing original key parameters of a secret key stored in the terminal device according to predetermined strategies, wherein the predetermined strategies comprises an encryption algorithm and a segmenting rule (S102); storing dispersedly the processed data with discrete internal memories (S104). With the present invention, safety and performance of system are improved.
