Abstract
A chipset and a host controller, including a storage host controller for a storage device and an encryption and decryption engine that is implemented by hardware. The storage host controller analyzes a write command to obtain write command information, and provides the write command information and write data to the encryption and decryption engine. The encryption and decryption engine combines a data drive key with the write command information to encrypt the write data and provides the encrypted write data to the storage host controller to be written into a storage device via a communication port.
