Secure domain join for computing devices
First Claim
Patent Images
1. A method comprising:
- acquiring security domain access credentials on a computing device by;
storing a persistent identity on the computing device,deriving data that includes the security domain access credentials from the persistent identity, andtransferring the derived data to a security domain to allow the computing device to join the security domain;
wherein the persistent identity is stored in a secure identity processing area (SIPA), and wherein the SIPA is located in the computing device;
wherein a trust relationship that allows a secure domain join of the computing device to the security domain is established between a persistent account stored in a security domain and the persistent identity in the SIPA;
wherein the SIPA and a secure data center allow the computing device to obtain a cryptographically authenticated operating system at least partially in response to the security domain access credentials.

Abstract
A technique is provided for acquiring security domain access credentials on a computing device. The security domain access credentials are acquired by storing a persistent identity on the computing device, and deriving data that includes the security domain access credentials from the persistent identity. The derived data is transferred to a security domain to allow the computing device to join the security domain.

8. An apparatus comprising:
-
a computing device configured to acquire security domain access credentials, wherein the computing device stores a persistent identity, further wherein the computing device derives data that includes the security domain access credentials from the persistent identity, further wherein the computing device transfers the derived data to a security domain that allows the computing device to join the security domain; wherein a secure identity processing area (SIPA) stores the persistent identity, wherein the SIPA is located in the computing device; wherein the SIPA and the secure data center allow the computing device to obtain a cryptographically authenticated operating system at least partially in response to the security domain access credentials. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
