【摘要】 现代社会步入数字信息化高度发达的时代，计算机和网络遍及社会的每一个角落，信息安全和知识产权不可侵犯也提到了一个新的高度，如何保证数据信息的安全和软件知识产权成了信息技术领域关心的热点问题。 论文首先介绍了加密理论基础及实现方法，然后详细分析了USB总线规范和技术特点，在研究软件加密基本理论、典型技术和经典加密算法的基础上，分析比较了现有软件加密技术的优点和不足，并研究和论证了基于USB的高强度软件加密方案，提出了具有自主知识产权的高强度软件加密平台实现方法，设计了具体硬件实现电路和软件流程，并对高层和底层软件设计中的可靠性问题进行了探讨。 论文以当今业界的主流DSP芯片TMS320VC54X系列和通用PCI接口芯片AMCC S5933为基础，介绍了数字信号处理器和PCI总线的概念，设计并实现了基于PCI接口的通用数据加密卡监控软件，对通用数据加密卡存在的问题作了具体分析，提出了改进方法。更多还原

【Abstract】 Modern society has stepped into a highly developed digital informational age. Computer and Network has spreaded all over the society. Information security and sciential property right have been risen to a new level. It is a focused problem that how to protect data and software sciential property right in field of informational technology.Firstly, the basic principle and method of encryption are recommended in the paper. Then the basic principle of software encryption, typical technologies and classical encrypted arithmetic are discussed. The merits and disadvantages of software encryption technology are compared. The project of software encryption based on USB is researched and proved . The method of realization which based on software encryption platform is promoted. The circuit of hardware and flow chart of software are designed in the paper. The reliability of software design in high level and low level is discussed.The concept of digital signal process and PCI bus based on main stream DSP chips, TMS320VC54X serials and PCI interface chips, AMCC S5933, are recommended. The watch and control software for general data encryption card based on PCI interface is designed and realized. The problems of the card are particularly analysed and the improving methods are promoted.更多还原
