Patent ID: 7290142

Claim:
A method for initializing a SNMP (simple network management protocol) v3 device using an SNMP agent in the SNMPv3 device and an SNMP manager remote from the SNMPv3 device, comprising: utilizing a Diffie-Hellman key exchange protocol by the SNMP manager and the SNMP agent to enter an initial privacy key and an initial authentication key into the SNMPv3 device, wherein said utilizing step includes: generating an associated random number and public value by both the SNMP manager and the SNMP agent; passing the public value of the SNMP manager to the SNMP agent in a configuration file; reading, by the SNMP manager, the public value of the SNMP agent through a SNMP request using an initial valid user having access to the public value of the SNMP agent; computing a shared secret, by the SNMP agent and the SNMP manager, using the Diffie-Hellman key exchange protocol; converting the shared secret into a readable password; converting the readable password into a secret key; and setting the initial authentication key and the initial privacy key to the value of the secret key, wherein each of said converting steps are independently performed by both the SNMP agent and the SNMP manager.
