Security
Establishing a secure connection between two systems across the Internet is a
significant task. A system must be assured that it is connected to its intended
recipient system. Communications must be protected from interception, playback,
decoding, or modification by third parties. Data monitoring, tampering, and
spoofing pose significant challenges to establishing secure communications.
Voice Services use the RSA Public Key Cryptosystem™ to provide secure
communications. A public key cryptosystem is a complex mathematical method to
secure digital communications. Public key encryption uses two algorithmic keys:
a public key used to encode the data and a private key required to decode it. The
encryption key is usually made public and the decryption key is kept secret.
Voice Services use two additional types of keys to create two levels of security.
Default keys are common to all Voice Services and Control Centers, while unique
keys are generated for each individual Voice Service and Control Center. To
communicate with other Voice Services, a Voice Service or the Control Center
must have the appropriate security keys. All Voice Services and Control Center
applications have the default key when installed; if the default key is disabled,
unique keys must be distributed to new Voice Services or Control Centers through
a key management system.
System Administration Using the Control Center
The Control Center is the configuration, operation, and management application
that interfaces with all Voice Services. The Control Center is a Microsoft
Windows-based, 32-bit application with a graphical user interface (GUI). It
provides component-specific services for each of the Voice Service products and
also affects how some Voice Service client applications function.
