Cryptography > Communication System Using Cryptography > Having Compression Having CompressionHaving Compression patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.05/24/07 - 20070116289 - Non-deterministic number generation A method for determining the entropy of a noise source providing a bit flow, a method and a device for generating a bit flow, including parallelizing the bit flow to obtain first words over a first number of bits, applying to the successive words a compression function, and evaluating a ... 05/17/07 - 20070110243 - Data transfer system, data transfer device, data recording device and data transfer method It is an object to provide an efficient transfer of content data. In a case of transferring the content data from a data transfer device on a primary recording medium side to a data recording device to record the content data in a secondary recording medium, a data compression system ... 08/10/06 - 20060177062 - Methods for point compression for jacobians of hyperelliptic curves A cryptosystem based on a Jacobian of a hyperelliptic curve is being used. Various methods and apparati are provided for generating a compressed data format that identifies one or more points—on the Jacobian of the hyperelliptic curve, and for subsequently decompressing the compressed format data. ... 07/20/06 - 20060159267 - Device, method, and program for random number generation, encryption, and decryption recording medium Random number generating, encrypting, and decrypting apparatus, method thereof, program thereof, and recording medium thereof are provided. Random numbers for cryptographic applications are generated by a CA core. The CA core is composed of one-dimensional, two-state, and three-neighbor cell automaton. A total of three inputs for the own cell and ... 02/09/06 - 20060029230 - Recording apparatus, recording method, reproducing apparatus, and reproducing method A recording apparatus is disclosed, that comprises a compression process means for compressing an input digital signal corresponding to a predetermined compression process and segmenting the compressed digital signal into blocks, a fixed value generating means for generating a predetermined fixed value, an adding means for adding the fixed value ... 01/05/06 - 20060002555 - Dynamic content-aware memory compression and encryption architecture An architecture for content-aware compression and/or encryption of various segments of a application is disclosed. The architecture advantageously allows decompression and decryption units to be placed various levels of a memory hierarchy. ... 12/08/05 - 20050271208 - Protecting decrypted compressed content and decrypted decompressed content at a digital rights management client Theft of decompressed digital content as the content is being rendered is prevented. A requested slow-down of the rendering of the content is detected. Transfers of relatively large amounts of data are detected. A re-compressor-based requested slow-down of the rendering of the content is detected. A re-compressor re-compressing the content ... 08/18/05 - 20050180571 - Scrambling a compression-coded signal This invention provides methods and apparatus for protecting data transmitted using standard compression techniques such as Huffman coding. After input data is preprocessed (filtered, quantized, etc.), the data is encoded using a Huffman coder based on Huffman codes or code books which have been scrambled to change the order of ... ### FreshPatents.com Support |
