Assignee:
MICROSOFT CORPORATION - Redmond WA
International Classification:
H04L 9/00
US Classification:
713171
Abstract:
The claimed subject matter provides systems and/or methods that establish a decryption key for use with an attribute authority. The system can include components that identify a pseudonym based a global identifier (GID) associated with a user, initiates communication with the attribute authority, and selects a first random value utilized to determine a first value. The system also includes components that select a second random value, employs the first value and the second random value to generate a second value and a third value, receives the second value and the third value, identifies a third random value, and employs the second value, the third value, the first random value, and the third random value to determine a fourth value which is employed to determine a fifth value. The fifth value is employed to derive the decryption key for use with the attribute authority.
