Appl. No.:

10/877523

Inventors:

Carl E. Quinn - San Jose CA, US
Torbjorn Norbye - Concord CA, US
Joseph Paul Nuxoll - Los Gatos CA, US

Assignee:

Sun Microsystems, Inc. - Santa Clara CA

International Classification:

G06F 9/44

US Classification:

717107

Abstract:

One embodiment of the present invention provides a system that facilitates creating a hierarchical model from a programming language file that includes components. The system operates by obtaining a component from the programming language file. Upon obtaining the component, the system passes an encoder to the component and requests that the component encode itself using the encoder, thereby causing the encoder to generate elements in the hierarchical model. Each element includes an attribute that identifies the component, thereby allowing the component to be subsequently identified by referencing the attribute in the corresponding element in the hierarchical model.

International Classification:

H04L009/00

US Classification:

380/043000

Abstract:

Protection of digital content using a specific application of block cipher cryptography is described. The digital content is encrypted using an encryption key and a calculated initialization vector. The digital content includes a plurality of strides of data and each stride includes a string of data to be encrypted and a block of data to be encrypted. The calculated initialization vector to be used to encrypt the block of data is derived from the string of data in the stride to be encrypted. Furthermore, the initialization vector is calculated by performing an exclusive disjunction function on a seed value and the string of data for each stride.

Abstract:

The present disclosure is directed to a hierarchical data structure, and systems and techniques for using the same. In one example, first device data including a plurality of files and corresponding to message data generated by one or more components of a device during a time period, may be received. The first plurality of files may be stored on one or more data stores and at a first location according to a hierarchical data structure, the hierarchical data structure based at least in part on a message time, a data identifier, or a device identifier. Second device data, associated with the time period and including a second plurality of files, may be obtained. The second device data may then be stored at a second location on the one or more data stores according to the hierarchical data structure.
