ABSTRACT:
A method and system to store and distribute encryption keys commences when a service provider receives a product key from a content provider. The service provider encrypts content controlled by the content provider with a secure device public key of a secure device of the service provider. The secure device of the service provider decrypts the product key with the secure device public key and encrypts the product key with a storage key associated with the secure device. The product key is then stored at the service provider.
