ENTSCHLÜSSELUNG VON WIEDERHOLT ÜBERTRAGENEN DATEN IN EINEM VERSCHLÜSSELTEN KOMMUNIKATIONSSYSTEM |
摘要 |
The method generally includes the steps of receiving (201) a message (100) comprising a message indicator (101) and a plurality of encrypted blocks (103 through 111). When at least one block of the plurality of encrypted blocks is received with error, a second message is transmitted (215), which second message requests a retransmission of the at least one block. Upon receiving the retransmission of the at least one block without error, a keystream is generated (219) from the message indicator and the at least one block is decrypted using the keystream. |
