Digital data coding method, involves encrypting value with different initialization value into several encrypted values, and calculating part of parity symbols based on combination of encrypted values

摘要

The method involves encrypting a value (P-1) with a different initialization value (IV) into several encrypted values, and calculating a part of parity symbols based on a combination of the encrypted values, where the former value comprises a combination of all data source symbols. The former value is decrypted using a key (K-g), and the parity symbols are subjected to a decoding by an error correction code. Independent claims are also included for the following: (1) a method for transmitting coded data by implementing a digital data coding method (2) a digital data transmitter in a error correction code transmission system (3) a digital data receiver (4) a system for transmitting digital data in an application of a error correction code.
