Abstract
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.
