The chip of smart card stores private sensitive defense data of user, which concerns the benefits of customers and mobile phone service providers. To enhance the security and correctness of data with a limited capacity chip is a critical problem. The security module architecture of chip operating system in evolution data of CDMA2000 was designed, and the network access authentication algorithm was put forward with a space optimization method. The file access control, message authentication and data encryption for communication were designed, and the power down protection while modifying flash memory or update several files was introdued. Experimental results prove that the system can run stably, effectively and safely, and ensures the integrity, validity, authenticity of data in storage and transmission between smart card and network.
