摘要： 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.
摘要翻译：一种用于用由纠错码对源符号（Si）表示的数字数据进行编码的方法和系统。纠错码基于每个奇偶校验符号，产生几个源符号和至少一个先前等级的奇偶校验符号的奇偶校验符号（Pj）。至少一部分源符号被提交至少一个第一加密。获得的加密符号和其余的未密码的源符号被提交给纠错码。

摘要： 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.

摘要： 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.
摘要翻译：一种用于使用纠错码对由源符号（S i i i i i）表示的数字数据进行编码的方法和系统。基于对于每个奇偶校验符号，几个源符号和至少一个前一等级的奇偶校验符号，纠错码产生奇偶校验符号（P SUB）。至少一部分源符号被提交至少一个第一加密。获得的加密符号和其余的未密码的源符号被提交给纠错码。因此，本公开提高了所发送数据的安全性。本公开还与不同用户组的管理兼容。本公开适用于大规模广播系统，并提供与任何加密算法兼容的解决方案。此外，本公开特别适用于与LDPC型纠错码一起使用。
