  • Secure transmission with error correcting code
    Patent number: 8935527
    Abstract: The invention concerns a method and a system for encoding digital data (DATA) represented by source symbols, with an error correcting code generating parity symbols from, for each parity symbol, a plurality of source symbols and at least one parity symbol of preceding rank, including at least encrypting once (54) at least one first value (P1) into several encrypted values and integrating at least one combination (P1,j) of said encrypted values to compute (55) at least one part (P2 . . . Pn?k) of said parity symbols.
    Type: Grant
    Filed: December 20, 2006
    Date of Patent: January 13, 2015
    Assignee: STMicroelectronics SA
    Inventors: Aurelien Francillon, Vincent Roca, Christoph Neumann, Pascal Moniot
  • Method for ciphering data with error correction code
    Patent number: 7941725
    Abstract: A method and a system for coding digital data represented by source symbols (Si) with an error-correction code. The error-correction code generates parity symbols (Pj) based on, for each parity symbol, several source symbols and at least one parity symbol of preceding rank. At least a part of the source symbols is submitted to at least a first ciphering. The obtained ciphered symbols and the rest of the unciphered source symbols are submitted to the error-correction code.
    Type: Grant

  • Secure error-correction code
    Publication number: 20070174754
    Abstract: A method and a system for coding digital data represented by source symbols (Si) with an error-correction code. The error-correction code generates parity symbols (Pj) based on, for each parity symbol, several source symbols and at least one parity symbol of preceding rank. At least a part of the source symbols is submitted to at least a first ciphering. The obtained ciphered symbols and the rest of the unciphered source symbols are submitted to the error-correction code. Accordingly, the present disclosure improves the security of the transmitted data. The present disclosure is also compatible with the management of different groups of users. The present disclosure is well adapted to large-scale broadcasting systems and provides a solution compatible with any ciphering algorithm. In addition, the present disclosure is particularly well adapted for use with LDPC-type error-correction codes.
