A system and method of receiving and decrypting encrypted data using a key based upon an initial key used for encryption that is received at a receiving unit whereby a key is generated from the initial encryption key for decryption. The key used to encrypt the data at a transmitting unit periodically changes and is indicated to the receiving unit by using an odd or even flag that is attached to the encrypted data. By observing the flag and whether the flag polarity is odd or even, a new key corresponding to the key used for encryption is generated to provide uninterrupted reception of asynchronously transmitted data. |
