Apparatus, system and method for validating integrity of transmitted data

A method of generating an encrypted data packet, the method comprising:

• selecting a fixed length segment of a continuous encryption key stream;
• applying a portion of the fixed length segment to data to form an encrypted payload;
• generating a session count based in accordance with the fixed length segment;
• and
• combining the encrypted payload and the at least a portion of the session count to form an encrypted data packet.

A system comprising:

• a transmitter configured to generate an encrypted data packet, the transmitter comprising:
• an encryption engine configured to apply a portion of a fixed length segment of a continuous encryption key stream to data to form an encrypted payload;
• a session count generator configured to generate a session count in accordance with the fixed length segment;
• the encrypted data packet comprising the encrypted payload and at least a portion of the session count;
• and
• a receiver configured to receive the encrypted data packet, the receiver comprising:
• a session count evaluator configured to determine if a difference between a received session count within the encrypted data packet and a locally generated session count is less than a threshold;
• and
• a decryption engine configured to decrypt the encrypted payload by applying a portion of a current fixed length segment of a continuous decryption key stream to the data packet if the difference is less than the threshold.

A method comprising:

• receiving a data packet through a communication channel;
• the data packet comprising at least a portion of a session count;
• selecting a fixed length segment of a continuous decryption key stream based on the session count;
• and
• applying a portion of the fixed length segment by performing a bit per bit streaming encryption to decrypt a payload of the data packet.
