Abstract: Aiming at security level low of information storage and transmission in mobile computer system, this paper presents a design scheme of serial interface security module combined with actual application, it implements some functions, such as security module configuration, information encryption/decryption, self-destroy etc. The scheme has been applied in hand computer project, serial interface security module satisfies security demands of wireless communication and storage information in mobile computer system.

Key words: security module, information encryption/decryption, self-destroy

摘要： 针对目前移动计算机系统信息存储和传输安全水平较低的缺陷，该文结合具体应用，提出了一种串口安全模块的设计方案，实现了安全模块设置、信息加/解密、自毁等功能。该方案已经应用于某手持计算机项目中，增加的串口安全模块满足了移动计算机系统中无线通信和存储信息的安全性需求。
