Installation and Operations Manual
SSL
Secure Socket Layers (SSL) version 3 enables secure Web sessions between a Remote Power Manager and a remote
user. SSL provides two chief features designed to make TCP/IP (Internet) transmitted data more secure:
Authentication – The connecting client is assured of the identity of the server.
Encryption – All data transmitted between the client and the server is encrypted rendering any intercepted
data unintelligible to any third party.
SSL uses the public-and-private key encryption system by RSA, which also requires the use of digital certificates. An
SSL Certificate is an electronic file uniquely identifying individuals or websites and enables encrypted
communication; SSL Certificates serve as a kind of digital passport or credential.
The SSL Certificate for the -48 VDC product enables the client to verify the authenticity of the unit and to
communicate with the unit securely via an encrypted session, which protects confidential information from
interception.
