Abstract
A method for transmitting, by a transmitter, a packet to a receiver of a communication system. The packet including data encrypted according to a symmetric key encryption protocol by determining the value of a generation information and determining an encryption key according to the value of the generation information. The data to be included in the encrypted packet to be transmitted is encrypted according to the encryption key. A truncated information is calculated based on the generation information. A verification code for the encrypted packet is calculated according to the encrypted data and the first portion of the generation information. The encrypted packet to be transmitted is formed according to the truncated information, the verification code and the encrypted data.
