Abstract
An integrated circuit includes, in part, a key management unit configured to generate a seeding key during a start-up phase, an encryption module configured to encrypt data using the seeding key and deliver the encrypted data to a second integrated circuit, and an encoder configured to encode the seeding key and deliver the encoded seeding key to the second IC. The second integrated circuit includes, in part, a decoder configured to decode the seeding key. Each of the integrated circuits further includes, in part, a linear-feedback shift register that receives the same clock signals and loads the seeding key.
