Abstract
Systems and methods for security key transmission with strong pairing to a destination client are disclosed. A security key may be generated by an on-chip key generator, an off-chip device, and/or software. A rule may then be paired with the security key and an address associated with the security key. The rule may define permissible usage by a destination module, which is defined by the associated address. The rule may comprise a command word, which may be implemented using a data structure associated with a permissible algorithm type, a security key size, and/or a security key source.

An integrated circuit comprising:
- a security client configured to receive a security key sequence comprising a security key and a security command;
- and
- a key serializer configured to generate the security key sequence and transmit the security key sequence to the security client.
A method for security key transmission within an integrated circuit, the method comprising:
- generating, by a key serializer disposed on the integrated circuit, a security key sequence comprising a security key and a security command;
- transmitting, by the key serializer, the security key sequence to a security client disposed on the integrated circuit;
- and
- receiving, by the security client, the security key sequence.
A set-top box comprising:
- an integrated circuit comprising:
- a security client configured to receive a security key sequence comprising a security key and a security command;
- and
- a key serializer configured to generate the security key sequence and transmit the security key sequence to the security client.
