R0106-HP MSR Router Series Security Configuration Guide(V7)

NOTE:
SSH1 clients do not support secondary password authentication that is initiated by the AAA server.
• Publickey authentication—The server authenticates a client through the digital signature. In a
publickey authentication, a client sends the server a publickey authentication request that contains
the following information:
{ Username.
{ Public key of the client.
{ Publickey algorithm (or the digital certificate that carries the public key information).
The server examines the validity of the public key. If the public key is invalid, the authentication
fails. If the public key is valid, the server authenticates the client by using the digital signature.
Finally, the server informs the client of the authentication result. The device supports using the
public key algorithms RSA and DSA for digital signature.
For more information about public key configuration, see "Managing public keys."
• Password-publickey authentication—The server requires SSH2 clients to pass both password
authentication and publickey authentication. However, an SSH1 client only needs to pass either
authentication, regardless of the requirement of the server.
• Any authentication—The server requires clients to pass password authentication or publickey
authentication.
FIPS compliance
Some MSR routers support the FIPS mode that complies with NIST FIPS 140-2 requirements. Support for
features, commands, and parameters might differ in FIPS mode and non-FIPS mode. For more
information about FIPS mode, see "Configuring FIPS."
Security strength
By default, the device provides low encryption. To obtain high encryption, you must install the Strong
Cryptography feature license. This feature provides stronger cryptography, additional IPsec tunnels, and
higher encryption performance. For more information about obtaining the Strong Cryptography feature
license, see the release notes or contact your HP sales representative.
Support for features, commands, and parameters depends on the cryptography capability.
Configuring the device as an SSH server
You can configure the device as an Stelnet, SFTP, or SCP server. Because the configuration procedures
are similar, the SSH server represents the Stelnet, SFTP, or SCP server unless otherwise specified.
