Filed:

Dec 16, 2009

Appl. No.:

12/639950

Inventors:

Carl Melvin Ellison - New York NY, US
Charles G. Jeffries - Sammamish WA, US

Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

G06F 17/30

US Classification:

707800, 707E17005

Abstract:

Data stored on a storage medium can be referenced by multiple independently addressable active symbolic links, with each active symbolic link representing the data through a different transformation. The active symbolic links can be in the form of file system objects, such as files or directories. A single active symbolic link can reference the data stored in multiple collections, or, conversely, a subset of data from a single collection. Active symbolic links can be automatically created for common data transformations. Searching across active symbolic links referencing encrypted data can be performed by multiple protection-specific search engines, or a single search engine that can generate a protection-level aware search index.

Abstract:

In accordance with one or more aspects, an initial output string is generated by a random number generator. The initial output string is sent to a random number service, and an indication of failure is received from the random number service if the initial output string is the same as a previous initial output string received by the random number service. Operation of the device is ceased in response to the indication of failure. Additionally, entropy estimates for hash values of an entropy source can be generated by an entropy estimation service based on hash values of various entropy source values received by the entropy estimation service. The hash values can be incorporated into an entropy pool of the device, and the entropy estimate of the pool being updated based on the estimated entropy of the entropy source.
