ABSTRACT:
Aspects of the invention provide a method and system for coding information in a communication channel. More particularly, aspects of the invention provide an method and system for synchronous running encryption and/or encoding and corresponding decryption and decoding in a communication channel or link. Aspects of the method may include encoding and/or encrypting a first data using a first or second encoding table and/or a first or second encryption table. The method may indicate which one of the first or second encoding tables or which one of the first or second encryption tables were utilized for encoding and/or encrypting the said first data. The encoded and/or encrypted first data may subsequently be transferred downstream and decoded by synchronous decoder/decryptor using a corresponding decoding and/or decryption table. The corresponding decoding and/or decryption table may be determined based on the indicated first and/or second encoding and/or encrypting tables.
