iTP Secure WebServer Encryption

The iTP Secure WebServer can use three types of encryption:

•

Secure Socket Layer (SSL) encryption

•

Private Communications Technology (PCT) encryption

•

WebSafe2 encryption

Secure Sockets Layer (SSL) and Private Communications

Technology (PCT) Encryption

Because the iTP Secure WebServer complies with the SSL 3.0 and PCT standards,

the ability to use SSL and PCT encryption is built in. There is no need to acquire any

additional software or hardware to use this type of encryption.

The SSL and PCT protocols enable a Web client and server to authenticate one

another and enables both partners to protect exchanged data by using private

encryption keys that are used for a single session, and then discarded. A Web client or

server can be authenticated only by presenting a certificate obtained from a recognized

Certificate Authority (CA).

You can use SSL or PCT encryption by generating a key pair for the server, obtaining a

certificate from a CA, installing it, and making certain configuration changes. For more

information, see Using the Keyadmin Utility to Manage Keys and Certificates on

page 4-7.

WebSafe2 Encryption

The iTP Secure WebServer can be configured to provide WebSafe2 encryption. When

a WebSafe2 unit is used, the Web client and server observe SSL protocols when

communicating with each other, but the server hands off the most complex decryption

tasks to the WebSafe2 unit.

The WebSafe2 unit provides maximum security for the server’s cryptographic

information because:

•

The WebSafe2 unit encrypts the server’s cryptographic key with a key that is

stored only in the WebSafe2 unit itself.

•

It is not possible to use a network connection to access the contents of the

WebSafe2 unit or control it in any way.

The WebSafe2 unit is equipped with sensors to detect tampering and dangerous

fluctuations in temperature and voltage.

Note. WebSafe2 encryption is supported only on systems running G-series RVUs.
