Abstract
A remote boot process uses a secret to sign and/or seal the data necessary to remotely boot a client from a server on a network to ensure the integrity of the data. The secret is generated by the server and securely delivered to the client during the initial setup of the client. The secret contains a one-way encryption of the password for the client account on the server. Each side balances a signed message with a verify and a sealed message with an unseal. Subsequent transactions between the client and server are conducted using messages encrypted with a key generated by the server and securely delivered to the client in a message sealed using the secret. The secret can also be used in conjunction with an access data structure to prevent unauthorized users from accessing data stored on the server on behalf of the client or other users. In other aspects of the invention, the secret is replaced by a client private/public key pair.
