General Description of Tunneling
Tunneling is accomplished with two complementary products:
the Workgroup Edition and Personal Edition.
- The Workgroup
Edition, required for all tunneling (for authorization,
authentication, and management), connects two servers
to support confidential organization-to-organization communications,
or multiple Personal Edition clients.
- The Personal
Edition enables you to securely connect a client personal
computer to a server running the Workgroup Edition, in
your private intranet via the Internet.
allows information to be securely passed between a Server
and another computer over a public network, as if the two
were connected by a single physical wire.
The process of
sending information through tunnels is simple and straightforward.
After authenticating the tunnel client and the tunnel server,
information is encrypted by its sender, encapsulated into
TCP/IP data packets, and sent across the Internet as unreadable
and unrecognizable data.
Once they reach
their final destination, the packets are reconstituted,
and decrypted into a readable form. Note that a system running
the Workgroup or Personal Edition software may be a client,
while only a system running the Workgroup Edition may be
a server (tunnel management station).
Tunnel 97 employs RSA Public Key Cryptosystem (512 bit) for
authentication and session key exchange, and RSA RC4 Symmetric
Stream Cipher for bulk data encryption. Cryptographic identity
and keys are tied to the user, leaving the IP address free
to be dynamically assigned.
Once the authenticated
tunnel session is created, the tunnel server and tunnel
client automatically switch from public key encryption to
RC4-based secret key encryption to perform bulk data encryption
and transmission. At 30-minute intervals, the tunnel client
and server pass new session keys back and forth to decode
transmitted data. During data packet transmission, each
packet is integrity protected and authenticated by MD5.
with federal export regulations, the U.S. version of the
AltaVista Tunnel 97 employs a 128-bit RC4 key, while the
international version supports a 56-bit RC4 key. Previous
international versions of this product only supported a
40-bit RCA key.
a multinational tunnel, automatic arbitration reconciles
any encryption discrepancies transparently. This enables
both the tunnel client and server to operate in the highest
common encryption key mode supported.
This product is
classified as "ITAR (International Traffic in Arms Regulations)
Controlled." The usage and intent of this sensitive product
shall therefore comply to any related export and import
companies and organizations employ firewalls to protect the
information on their private networks from Internet invaders.
Because the AltaVista Tunnel 97 uses encryption and authentication
to protect that information as it is transmitted across the
Internet, it is a natural complement to any firewall.
However, a firewall
is not a prerequisite for the AltaVista Tunnel 97 which
delivers a highly flexible firewall-independent solution.
The AltaVista Tunnel 97 Workgroup Edition can run on a system
with the AltaVista Firewall or it can run on a separate
system behind a firewall that protects it from the Internet.
