Method and system for managing secure code loading in PC-slave devices

A system, comprising:

• one or more circuits for use in a slave device of a processing device, wherein said one or more circuits comprise a secure processor, said secure processor being operable to manage secure loading of execution code and/or data within said slave device, wherein said secure processor causes:
• decryption of said execution code and/or data by said slave device;
• and
• storage of said decrypted execution code and/or data in a restricted portion of a memory that is dedicated for use by said slave device, wherein said restricted portion of said dedicated memory resides outside of said slave device, said restricted portion of said dedicated memory being only accessible by said slave device.

A method, comprising:

• in a processing device comprising a slave device, said stave device comprising a secure processor:
• managing by said secure processor, secure loading of execution code and/or data within said slave device, wherein said secure processor causes:
• decryption of said execution code and/or data by said slave device;
• dynamically partitioning of a memory that is dedicated for use by said slave device into a restricted portion and an accessible portion, wherein said accessible portion of said dedicated memory is accessible by said slave device and one or more other components of said processing device;
• and
• storage of said decrypted execution code and/or data in said restricted portion of said memory that is dedicated for use by said slave device, said restricted portion of said dedicated memory being only accessible by said slave device.
