Ssl Commands - D-Link DGS-3224TGR Command Line Interface Reference Manual

Secure Sockets Layer or SSL is a security feature that will provide a secure communication path between a host and client
through the use of authentication, digital signatures and encryption. These security functions are implemented through the use of
a ciphersuite, which is a security string that determines the exact cryptographic parameters, specific encryption algorithms and
key sizes to be used for an authentication session and consists of three levels:
1. Key Exchange: The first part of the cyphersuite string specifies the public key algorithm to be used. This switch utilizes
the Rivest Shamir Adleman (RSA) public key algorithm and the Digital Signature Algorithm (DSA), specified here as the
DHE_DSS Diffie-Hellman (DHE) public key algorithm. This is the first authentication process between client and host as
they "exchange keys" in looking for a match and therefore authentication to be accepted to negotiate encryptions on the
following level.
2. Encryption: The second part of the ciphersuite that includes the encryption used for encrypting the messages sent between
client and host.
3. Hash Algorithm: This part of the ciphersuite allows the user to choose a message digest function which will determine a
Message Authentication Code. This Message Authentication Code will be encrypted with a sent message to provide
integrity and prevent against replay attacks. The switch supports two hash algorithms, MD5 (Message Digest 5) and SHA
(Secure Hash Algorithm).
These three parameters are uniquely assembled in four choices on the switch to create a three layered encryption code for secure
communication between the server and the host. The user may implement any one or combination of the ciphersuites available,
yet different ciphersuits will effect the security level and the performance of the secured connection. The information included
in the ciphersuites is not included with the switch and requires downloading from a thirs source in a file form called a
certificate. This function of the switch by utilizing a TFTP server. The switch supports SSLv3 and TLSv1, other version of SSL
may not be compatible with this switch and may cause problems upon authentication and transfer of messages from client to
host.
