Bandwidth efficient method and system for obscuring the existence of encryption in a communications channel

A network interface for obscuring the existence of data encryption, the network interface comprising:

• a controller operating to:
• generate a set of characters by using a set of encryption keys as an input to a pseudo-random function, each character corresponding to an index value;
• divide encrypted data into a plurality of parts;
• section each part of the plurality of parts into a plurality of groups;
• and
• encode each part by mapping each group of the plurality of groups to a character in the set of characters according to its corresponding index value;
• and
• a communication interface communicatively coupled to the controller, the communication interface operating to transmit the mapped characters through the communication network.

A system for obscuring the existence of data encryption in a communication network, the system comprising:

• a first network interface operating to:
• generate a set of alphabet characters by using a set of encryption keys as an input to a pseudo-random function, each alphabet character corresponding to an index value;
• divide encrypted data into a plurality of parts;
• section each part into a plurality of groups;
• encode each part by mapping each of the plurality of groups to a character in the set of characters according to its corresponding index value;
• and
• transmit the mapped characters through the communication network;
• and
• a second network interface operating to:
• receive an encoded data message, the encoded data message including the mapped characters;
• divide the encoded data message into a plurality of groups of characters;
• map each character to its corresponding index value to recreate the plurality of parts;
• and
• decrypt each part of the plurality of parts.
