    • Certain embodiments of the invention provide a method and system for memory to bus interface data encryption and decryption. A method for memory to bus interface data encryption and decryption may include encrypting data by a encryption/decryption engine or processor and transferring the encrypted data across a first bus interface to a data processing and/or storage device coupled to the first bus interface. The encryption engine may receive encrypted data from a device coupled to the first bus interface and decrypt the received encrypted data. In this regard, unencrypted data never traverses across the first bus interface, and is thereby not accessible to devices coupled to the first bus interface. An encryption function and a decryption function associated with the encryption/decryption engine may be integrated within a bus adapter, for example, an IDE bus adapter.
    • 本发明的某些实施例提供了一种用于存储器到总线接口数据加密和解密的方法和系统。 用于存储器到总线接口数据加密和解密的方法可以包括通过加密/解密引擎或处理器对数据进行加密,并将经加密的数据跨越第一总线接口传送到耦合到第一总线接口的数据处理和/或存储设备。 加密引擎可以从耦合到第一总线接口的设备接收加密数据,并对接收到的加密数据进行解密。 在这方面,未加密的数据永远不会穿过第一总线接口,并且因此不能被耦合到第一总线接口的设备访问。 与加密/解密引擎相关联的加密功能和解密功能可以集成在总线适配器(例如,IDE总线适配器)内。
