Abstract

System and method for generating and distributing an encryption/decryption key are disclosed and may include generating one or more keys by a key generator integrated within a chip. The generated one or more keys may be communicated directly from the key generator, via an on-chip broadcast serial link, to one of a plurality of on-chip addressable encryption/decryption devices. A particular one of the plurality of on-chip addressable encryption/decryption devices processes one or more received packets that include its own address utilizing the one or more keys. The at least one key may be serialized and encapsulated into a key packet. The encapsulating may include encapsulating an address of the one of the plurality of on-chip addressable encryption/decryption devices in the key packet.
