Data accessing device and method
A data accessing device to access a storage element that stores encrypted data is provided. The data accessing device includes a processing circuit, a storage controller, a decrypting circuit and a combinational logic circuit. The processing circuit generates an accessing address and decryption related information according to an accessing command. The storage controller receives the accessing address and accesses corresponding encrypted data accordingly. The decrypting circuit receives the decryption related information and a pre-stored key to generate a decrypting cipher accordingly. The combinational logic circuit receives the corresponding encrypted data and the decrypting cipher to perform a logic operation to generate decrypted data accordingly that enables the processing circuit to access the decrypted data.
