Secure Socket Layer (Ssl) - D-Link DXS-3326GSR Manual

When this window appears, click the Enable Admin button revealing a dialog box for the user to enter authentication
(password, username), as seen below. A successful entry will promote the user to Administrator level privileges on the
Switch.

Secure Socket Layer (SSL)

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. The Switch supports two types of cryptology algorithms:
Stream Ciphers – There are two types of stream ciphers on the Switch, RC4 with 40-bit keys and RC4 with 128-
•
bit keys. These keys are used to encrypt messages and need to be consistent between client and host for optimal
use.
CBC Block Ciphers – CBC refers to Cipher Block Chaining, which means that a portion of the previously
•
encrypted block of encrypted text is used in the encryption of the current block. The Switch supports the 3DES
EDE encryption code defined by the Data Encryption Standard (DES) to create the encrypted text.
