Embodiment Construction

[0067] get-request

[0068] Fig. 1 schematically depicts a first computer unit C1 and a second computer unit C2. The first computer unit C1 has an SNMPv1 management operator MA and a first agent agent PA1.

[0069] The second computer unit C2 has an SNMPv1 agent AQ and a second agent agent PA2 on the side of the second computer unit C2.

[0070] In a first step 101, an acquisition request is formed in the first computer unit C1. Formation of a get request is understood to mean the encoding of an encoded digital message into an encoded message using the encoding format of the SNMPv1 network protocol. This takes place in the first device 101 of the first computer unit C1 for encoding digital messages using the Internet protocol encoding format.

[0071] In a second step 102, a get-request, ie a coded message CN, is sent from the first device N1 to the first agent-intermediary PA1 on the part of the first computer C1.

[0072] In a third step 103 the encoded message CN is rec...

Abstract

The invention describes a method for a network protocol such as SNMPv1, according to which a message is encoded (101) into a coded message in a first computer unit (C1) using the encoding format of the network protocol (CN). The encoded message (CN) is cryptographically processed (104). The resulting cryptographically processed message (KBN) is re-encoded using the encoding format of the network protocol (105). The cryptographically processed message (CKN) encoded in this way is transmitted from the first computer unit (C1) to the second computer unit (C2). The message received in the 2nd computer unit (C2) is then decoded (109) according to the encoding format of the network protocol, and the decoded message (DKN) is subjected to reverse cryptographic processing (110). The inverse cryptographically processed message (IKN) is then re-decoded according to the encoding format of the network protocol.

Description

technical field [0001] Various network protocols are known within the scope of the management of computer networks. The task of managing computer networks is becoming more and more difficult due to the high popularity of computers and their ever-increasing networking, while the network management systems required for this are also becoming more and more powerful. In the field of computer network management, the security issues of network management are always gaining more and more significance. The security of network management has a great relationship with the security technology used in the system. Background technique [0002] Various network protocols for network management are known from the literature (M. Rose, The Simple Book, PTR Prentice Hall, 2. Edition, ISBN 0-13-177254-6, pp. 59-91, 1994), for example in 1 Type (SNMPv1 and Type 2 (SNMPv2) Simple-Network-Management-Protocol (SNMP) or Common-Management-Internet-Protocol (CMIP). [0003] For monitoring and contr...
