Description
Interface Summary | |
---|---|
AuthenticationProtocol | The AuthenticationProtocol interface defines a common
interface for all SNMP authentication protocols. |
PrivacyProtocol | The PrivacyProtocol interface defines a common
interface for all SNMP privacy protocols. |
SecurityModel | The SecurityModel interface as described in RFC3411 section 4.4. |
SecurityParameters | The SecurityParameters interface represents the security
parameters in a SNMPv3 message. |
SecurityProtocol | The SecurityProtocol class defines common methods of
authentication and privacy protocols. |
SecurityStateReference | The SecurityStateReference interface is an empty marker
interface for security model dependend state references. |
Class Summary | |
---|---|
AuthGeneric | The abstract class AuthGeneric implements common operations for SNMP authentication protocols, such as MD5 and SHA. |
AuthMD5 | The AuthMD5 class implements the MD5 authentication protocol. |
AuthSHA | The SHA class implements the Secure Hash Authentication. |
ByteArrayWindow | The ByteArrayWindow provides windowed access to a subarray
of a byte array. |
DecryptParams | Parameter class for encrypt and decrypt methods of SecurityProtocol . |
Priv3DES | Privacy protocol class for Triple DES (DESEDE). |
PrivAES | Base class for PrivAES128, PrivAES192 and PrivAES256. |
PrivAES128 | Encryption class for AES 128. |
PrivAES192 | Encryption class for AES 192. |
PrivAES256 | Encryption class for AES 256. |
PrivDES | Privacy protocol class for DES. |
SecurityLevel | The SecurityLevel interface contains enumerated values
for the different security levels. |
SecurityModels | The SecurityModels class is a collection of all
supported security models of a SNMP entity. |
SecurityProtocols | The SecurityProtocols class holds all authentication and
privacy protocols for a SNMP entity. |
USM | The USM class implements the User Based Security Model (USM)
as defined in RFC3414. |
UsmSecurityParameters | |
UsmSecurityStateReference | The UsmSecurityStateReference holds cached security data. |
UsmTimeEntry | The UsmTimeEntry class represents time synchronization
information associated with an engine ID. |
UsmTimeTable | The UsmTimeTable class is a singleton that stores USM user
information as part of the Local Configuration Datastore (LCD). |
UsmUser | The UsmUser class represents USM user providing information
to secure SNMPv3 message exchange. |
UsmUserEntry | The UsmUserEntry class represents a user in the
Local Configuration Datastore (LCD). |
UsmUserTable | The UsmUserTable class stores USM user
information as part of the Local Configuration Datastore (LCD). |
UsmUserTable.UsmUserKey |
Provides classes and interfaces for authentication and privacy of SNMP(v3) messages.
The org.snmp4j.security
package contains three groups of
classes and interfaces:
Authentication as well as privacy protocols are security protocols and
thus both are derived from the common interface SecurityProtocol
.
In order to be able to use a security protocol with SNMP4J, the protocol
implementation class has to be registered with the
SecurityProtocols
singleton, which provides access to
authentication and privacy protocols.
All SNMP4J authentication protocol implementations have to implement the
AuthenticationProtocol
interface. SNMP4J provides implementation
for the following authentication protocols:
AuthMD5
andAuthSHA
.
All SNMP4J privacy protocol implementations have to implement the
PrivacyProtocol
interface. SNMP4J provides implementation
for the following privacy protocols:
PrivDES
andPrivAES128
.
PrivAES192
.
PrivAES256
. In
order to be able to use 256bit strong encryption, the strong encryption
enhancement package has to be downloaded and installed.
All SNMP4J security models have to implement the SecurityModel
interface. Before a security model can be used with SNMP4J, it has to be
registered with the SecurityModels
singleton which provides
access to security models. SNMP4J implements a single security model, the
User Based Security Model (USM).
The USM
class uses a user name table (which contains
user names) and a user table (which contains localized user information) to
store user information. A time table is used to store time information
about SNMP engines to protect SNMP communication against replay attacks
if the corresponding security level has chosen.
The following UML class diagram shows the most important classes of the
org.snmp4j.security
package and their relationships
