| 20090313480 | METHOD AND SYSTEM FOR OBFUSCATING A GRYPTOGRAPHIC FUNCTION - A method of proctecting an integrity of a data processing system. The method comprises determining a data string to be protected, an integrity of the data string being an indication of the integrity of the data protecessing system. Computing a set of parameters representing a predetermined data processing function, using a redundancy in the set of parameters to incorporate the data string into a bit representation of the set of parameters. Enabling the system to process data according to the set of parameters. The set of parameters represents at least part of cryptographic algorithm key. The set of parameters represents a netword of look-up tables. The network of look-up tables comprises a plurality of look-up tables of a white-box implementation of a data processing algorithm. The data processing algorithm comprises a cryptographic algorithm. | 12-17-2009 |

| 20080228693 | Recycle Bin Function - A method for implementing a recycle bin function for a first electronic device comprising data storage for storing electronic files. The method comprises receiving an indication to delete a file stored on the first electronic device, determining a further electronic device also storing the file, storing on the first electronic device a reference to the further electronic device and the file, and releasing the data storage capacity occupied by the file on the first electronic device so that the capacity is available for other uses. | 09-18-2008 |
| 20100296649 | CRYPTOGRAPHIC PROCESSING OF CONTENT - A system for cryptographic processing of content comprises an input for receiving the content. A plurality of look-up tables represents a white-box implementation of a combined cryptographic and watermarking operation. The look-up tables represent processing steps of the combined cryptographic and watermarking operation and the look-up tables being arranged for being applied according to a predetermined look-up scheme. The look-up scheme prescribes that an output of a first look-up table of the plurality of look-up tables be used to generate an input of a second look-up table of the plurality of look-up tables. The combined cryptographic and watermarking operation comprises a cryptographic operation and a watermarking operation. A control module looks up values in the plurality of look-up tables in dependence on the received content and in accordance to the look-up scheme, thereby applying the combined cryptographic and watermarking operation to the content. | 11-25-2010 |
