Abstract: A method, system and apparatus of a secure debug interface and memory of a media security circuit and method are disclosed. In one embodiment, a host processor, an external hardware circuit to encrypt an incoming data bit communicated to a debug interface using a debug master key stored at a pointer location of a memory (e.g., the memory may be any one of a flash memory and/or an Electrically Erasable Programmable Read-Only Memory (EEPROM)) and to decrypt an outgoing data bit from the debug interface using the debug master key, and a media security circuit having the debug interface to provide the pointer location of the memory having the debug master key to the external hardware circuit.

Abstract: A method includes encrypting, in a security engine associated with a memory/storage controller of a memory/storage device in a data processing device, a pre-encrypted/unencrypted data stream associated with a multimedia content in accordance with a data write request to transfer the pre-encrypted/unencrypted data stream to the memory/storage device using a security key configured to uniquely identify the data processing device during each data write session and a security flag configured to uniquely identify each data write session during a secure mode of operation. The method also includes transmitting the security engine encrypted data stream to the memory/storage device in accordance with the data write request, and decrypting the security engine encrypted data stream using the security key and the security flag in accordance with a data read request to read the security engine encrypted data stream stored in the memory/storage device.

Abstract: The method, system, and apparatus of key exchange through a scramble methodology and system is disclosed. In one embodiment, the method includes generating a security key associated with a protected media content, disassembling the security key (e.g., may be an unencrypted key) into a set of key bits, generating non-key bits (e.g., may be arbitrarily and/or randomly created binary numbers), placing the non-key bits disbursed between at least some of the set of key bits based on an algorithm of a control register module of a scatter module, algorithmically specifying a number of the set of key bits and the non-key bits in a packet, and communicating the packet and other packets each having the non-key bits disbursed between at least some the set of key bits of each of the packet and the other packets to a gather module.

Abstract: A method, system and apparatus of an author website in a commerce environment are disclosed. In one embodiment, a system includes a host processor; a first security circuit to re-encrypt a work of authorship protected by an encryption standard using a proprietary key after an authorization module uses an algorithm of the encryption standard to verify that the system has permission to playback the work of authorship; a system memory to store a proprietary encrypted content generated through the re-encryption process of the first security circuit; and a second security circuit of a display module to independently generate the proprietary key using an index pointer provided from the first security circuit to the second security circuit through the host processor and to decrypt the proprietary encrypted content of the system memory using the independently generated proprietary key.
