Method and system for data protection in a mobile multimedia processor

摘要

Certain aspects of a method and system for protecting data during mobile communication may comprise a mobile multimedia processor that decrypts an encrypted algorithm in hardware within the mobile multimedia processor. The mobile multimedia processor may be adapted to utilize the decrypted algorithm to decrypt data in software. The mobile multimedia processor may be adapted to decrypt instructions for the encrypted algorithm as the instructions enter an instruction cache. The mobile multimedia processor may be adapted to protect the decrypted data by performing a hash operation of the decrypted data and check a result of the hash operation.
