Premium Network encryption products are designed for large and medium customers that need
high-end security for their network infrastructure. Premium products can be used in
Gateway or Bridge mode. In Gateway mode the product behaves
like a router with different subnets on its plain and crypt interface. The complete IP
packets are encrypted and placed into a new packet to be routed to its destination. Gateway
mode supports “Subnet Based Encryption”, an advanced concept used to separate user groups in
organizations. With this concept, some groups of users can communicate encrypted, while traffic
to other stations remains unchanged in plain text. For example, the traffic from the board of
directors to the development department is encrypted, while the traffic from the development
department to all other departments is not. Subnet-Based-Encryption allows a step by step rollout
of the products wherever security is required.
In contrast the Bridge mode encrypts the payload and leaves the existing IP header almost unchanged.
This technique has its advantage when MPLS networks are used. Bridge mode Cryptors uses a set of
rules, similar to a firewall. The rules define what is encrypted and what is not.
All CE-Infosys networking products support the Enhanced IPSec protocol, an invention that makes
Cryptors immune against known networking and cryptographic attacks. Most important is the function
to change the key used for the encryption of an IP packet with every packet. This reduces the amount
of data for a cryptographic analysis to 1500 byte. This is by far too little to be useful for any attack.
Premium Cryptors are fully encapsulated and can be used in unfriendly environmental conditions, such as
in the desert where small sand particles are in the air.
The external power supply contributes to the reliability of the products. Experience tells us that some
electric components in power supplies are stressed and have a higher tendency to fail. This is not an
issue if the power supply can be changed without reinstalling the Cryptor. The external 12 Volt input
allows the Cryptors to be used in mobile installations like cars, vessels, airplanes or helicopters. The
absence of mechanically moving parts in Cryptors contributes to their high reliability.
Cryptors are quiet and produce no noise during operation; therefore they are also ideal to be used at
office workplaces. For installations at the data center a slide mounting bracket is available
