usmDHKickstartMyPublic
Module: SNMP-USM-DH-OBJECTS-MIB
OID (symbolic): SNMP-USM-DH-OBJECTS-MIB::usmDHKickstartMyPublic
OID (numeric): 1.3.6.1.3.101.1.2.1.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The agent's Diffie-Hellman public value for this row. At
initialization, the agent generates a random number and derives its public value from that number. This public value is published here. This public value 'y' equals g^r MOD p where g is the from the set of Diffie-Hellman parameters, p is the prime from those parameters, and r is a random integer selected by the agent in the interval 2^(l-1) <= r < p-1 < 2^l. If l is unspecified, then r is a random integer selected in the interval 0 <= r < p-1
The public value is expressed as an OCTET STRING 'PV' of length 'k' which satisfies
k y = SUM 2^(8(k-i)) PV'i i = 1
where PV1,...,PVk are the octets of PV from first to last, and where PV1 != 0.
The following DH parameters (Oakley group #2, RFC 2409, sec 6.1, 6.2) are used for this object:
g = 2 p = FFFFFFFF FFFFFFFF C90FDAA2 2168C234 C4C6628B 80DC1CD1 29024E08 8A67CC74 020BBEA6 3B139B22 514A0879 8E3404DD EF9519B3 CD3A431B 302B0A6D F25F1437 4FE1356D 6D51C245 E485B576 625E7EC6 F44C42E9 A637ED6B 0BFF5CB6 F406B7ED EE386BFB 5A899FA5 AE9F2411 7C4B1FE6 49286651 ECE65381 FFFFFFFF FFFFFFFF l=1024
What is usmDHKickstartMyPublic?
Publishes the agent's own Diffie-Hellman public value, generated at initialization from a randomly selected private number and the configured DH parameters. Admins or management stations read this value to complete a Diffie-Hellman exchange during initial "bootstrap" provisioning of SNMPv3 credentials on a device that has no keys configured yet. A newly deployed device might expose a long octet-string public value here that a provisioning tool reads to derive the shared secret used to seed that device's first SNMPv3 user.
