The Cyphercell is a high speed data encryptor which can secure voice, data and video information transmitted over Asynchronous Transfer Mode (ATM) networks at data rates up to 155 Megabits per second.
The Cyphercell provides access control and authentication between secured sites, and confidentiality of transmitted information using the DES algorithm. The unit can be added to an existing ATM network with transparency to the user and network equipment.
Confidentiality of the transmitted information is achieved by encrypting the payload of the ATM cells while leaving the ATM header unchanged. This facilitates switching of the cell through the ATM network. Operation and maintenance (OAM) cells are not encrypted enabling ATM management functionality to be maintained.
Key management and authentication are based on RSA public key cryptography and X.509 certificates providing an automated key management system.Any combination of encrypted or unencrypted virtual circuits can be configured, up to a maximum of 65,536 active connections. Each encrypted virtual circuit uses different encryption keys.
The Cyphercell can be remotely managed by using the CypherManager, a SNMPv3 compliant management station using a secure management session.
