摘要： 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. Wherein, the decryption unit invokes corresponding MK according to the MKI and decrypts the encrypted software section, and directly transfers the decrypted software code and/or data to the processing and cache unit.
摘要翻译：本发明提供一种用于处理至少一个加密软件的中央处理单元。加密软件包括至少一个加密的软件部分。加密的软件部分用管理密钥MK进行加密，并且使用设备密钥DK将MK加密为加密的MK。中央处理单元包括处理和高速缓存单元和加密单元。加密单元包括用于存储DK的设备密钥存储单元，用于存储MK的多个管理密钥存储单元，其中与管理密钥索引MKI对应的每个管理密钥存储单元和解密单元。解密单元用DK解密加密的MK以获得MK，将MK存储到管理密钥存储单元，并输出与管理密钥存储单元相对应的MKI，因此MKI被用于对应于加密的软件部分。其中，解密单元根据MKI调用相应的MK，解密加密的软件部分，并将解密的软件代码和/或数据直接传送到处理和高速缓存单元。
