Abstract
Aspects of an encryption/decryption key generation and distribution may include generating one or more keys for use by one of a plurality of encryption/decryption devices coupled to a serial link within a chip. The generated keys may be transmitted via, for example, a high speed serial link to which one or more of the encryption/decryption devices in the chip may be coupled. The encryption/decryption devices coupled to the serial link may be adapted to examine or identify the transmitted key packets on the serial link and determine whether a particular key packet contains a key that which should be utilized by a particular one of the encryption/decryption devices. Upon identification of a key, the key may subsequently be processed and/or utilized by an integrated encryption/decryption processor associated with the encryption/decryption device to which the encryption key belongs.
