  • Method and central processing unit for processing encrypted software
    Patent number: 8286001
    Abstract: The present invention provides a central processing unit for processing at least one encrypted software. The encrypted software comprises at least one encrypted software section. The encrypted software section is encrypted with a management key MK, and the MK being encrypted with a device key DK as a encrypted MK. The central processing unit comprises processing and cache unit, and cryptographic unit. The cryptographic unit comprises device key storage unit for storing the DK, a plurality of management key storage units for storing MKs, wherein each management key storage unit corresponding to a management key index MKI, and decryption unit. The decryption unit decrypts a encrypted MK with the DK to obtain a MK, stores the MK to a management key storage unit, and output a MKI corresponding to the management key storage unit, thus the MKI is used to correspond to the encrypted software section.
