Patent number: 7779249Abstract: A host securely transmits content to a peripheral thereof. The peripheral has a symmetric key (PK) and a copy of (PK) encrypted according to a public key (PU) of an entity ((PU(PK))). In the method, the host receives (PU(PK)) from the peripheral, and sends (PU(PK)) to the entity. The entity has a private key (PR) corresponding to (PU), applies (PR) to (PU(PK)) to obtain (PK), and sends (PK) back to the host. The host receives (PK) from the entity, encrypts at least a portion of the content according to (PK), and transmits the encrypted content to the peripheral. The peripheral may then decrypt the encrypted content based on (PK). A bind key (BK) encrypted by (PK) ((PK(BK))) may accompany (PU(PK)), where the content is to be encrypted according to (BK). Thus, (PK) is not revealed to the host.Type: GrantFiled: December 10, 2008Date of Patent: August 17, 2010Assignee: Microsoft CorporationInventors: Brian Evans, Ajitesh Kishore, M. Jay Parks
