Embodiment Construction

[0012] It should be understood that the present aspects can be implemented in various forms of hardware, software, firmware, special purpose processors or combinations thereof. The invention is preferably implemented in software comprising program instructions tangibly stored on one or more program storage devices (e.g., floppy disk, RAM, CD-ROM, ROM, flash memory) and available on Execute on any device, machine or platform including appropriate architecture. It should also be understood that because certain system elements or method steps are preferably implemented in software, actual connections may vary depending on how the invention is programmed.

[0013] refer to figure 1 , a block diagram illustrating a system 10 for initializing devices managed by SNMPv3 according to an exemplary embodiment of the present invention. More specifically, system 10 includes a DOCSIS cable modem system between a CMTS (cable modem termination system, cable modem termination system) 16 and ...

Abstract

A system and method for initializing an SNMP agent in SNMPv3 mode. In one aspect of the invention, a method is provided that allows an operator to securely enter the initial SNMPv3 privacy and authentication keys into an SNMPv3 device and cause the device to enter in SNMPv3 mode. The SNMP manager and SNMP agent both generate an associated random number and public value (steps 100, 101, 200, 201). The SNMP manager passes its public value to the SNMP agent in a configuration file, which causes a proprietary MIB element in the SNMPv3 device to be set with the public value of the SNMP manager (steps 202, 204). The SNMP manager reads the public value of the SNMP agent through an SNMP request using an initial valid user having access to the public value of the SNMP agent (steps 103, 203). The SNMP agent and SNMP manager each independently compute a shared secret using the Diffie-Hellman key exchange protocol (steps 105, 204). The SNMP manager and SNMP agent each independently convert the shared secret into the same readable password (steps 106, 205), convert the readable password into the same secret key (steps 107, 206) and set the initial authentication key and the initial privacy key to the value of the secret key (steps 108, 207).

Description

technical field [0001] In general, the present application relates to a system and method for initializing a Simple Network Management Protocol (simple networkmanagement protocol, SNMP) agent (agent), and in particular, relates to a first user for SNMPv3 network management equipment Systems and methods for generating authentication and private keys and securely entering these keys into the device to initialize the device into SNNDv3 mode. Background technique [0002] Generally speaking, SNMP is a standard application layer protocol used in the network to facilitate the exchange of management information between networked devices. The framework of SNMPv3 defines standard security and known access control protocols as user-based security model (User-Based Security Model, USM) and observation-based access control model (View-Based Access Control Model, VACM). The SNMPv3 standard is an extensible bare-bones protocol that allows equipment vendors to incorporate some of their ow...
