METHOD AND COMPUTER SYSTEM FOR CODING A MESSAGE

摘要

According to the invention, a message is coded (101) for a network protocol, for example for SNMPv1, in the first computer unit (C1) using the coding format of the network protocol, to produce a coded message (CN). The coded message (CN) is subjected to a cryptographic process (104). The resulting cryptographically processed message (KBN) is then coded again using the coding format of the network protocol (105). The resulting coded cryptographically processed message (CKN) is transferred from the first computer unit (C1) to the second computer unit (C2). The received message is then decoded in the second computer unit (C2) in accordance with the coding format of the network protocol (109), and the decoded message (DKN) is subjected to an inverse cryptographic process (110). The inversely crytptographically processed message (IKN) is then decoded again in accordance with the coding format of the network protocol.
