Abstract
A method of generating an encryption key during the manufacturing process of a device includes randomly generating a seed, encrypting a unique identifier disposed in the device to obtain a first encryption key, encrypting the first encryption key using a public key to obtain a second encryption key, and sending the second encryption key and the seed to a software provider. The method further includes receiving the second encryption key and the seed by the software provider and decrypting the second encryption key using a private key to recover the first encryption key. The manufacturer then encrypts a program code using the recovered first encryption key and installs the seed in a certificate that is associated with the encrypted program code.
