java.lang.Objectcom.sun.management.internal.snmp.SnmpModelImpl
com.sun.management.snmp.usm.SnmpUserSecurityModel
public class SnmpUserSecurityModel
FOR INTERNAL USE ONLY. This is the default implementation of the User
Security Model defined in RFC 2574, "Usm for Snmp V3".
It handles timeliness, authentication and encryption.
It is compliant with the defined public interface SnmpUsm
.
It can be replaced by any Usm compliant model.
It manages a set of distant engine status (in case of manager use).
These engine proxies are storing the distant timeliness related status.
