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.

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.

Abstract: An ATM routing switch has a buffer circuit for holding cells located on queues at output ports, the buffer having a first reserve buffer capacity for cells of a first type requiring integrity of cell transmission and a first designation for use in determining a permitted path through the network, a second reserve buffer capacity for cells of the first type having a second designation for use in determining a different permitted path in the network and a third reserve buffer capacity for cells of a second type accepting some loss of cells in transmission, flow control circuitry operating to limit input of cells of either the first or second type if predetermined thresholds for the first, second or third buffer capacities are reached.
