A secure, configurable and customized multimode Bulk Encryptor

This paper describes the indigenous development of a secure, inter-department Bulk Encryption Unit in enterprise network systems, which is a special purpose device for securing the data communication between two parties in a VPN/ enterprise network. It is a hardware which will help organizations, institutes and enterprises to protect data against eaves-droppers and will protect sensitive information against unauthorized access. The services provided by encryption equipment can be summarized as data security, traffic flow security and authentication. The equipment provides information and communication security by encrypting/decrypting data over El links in the tactical area. It operates in duplex traffic working mode at transmission rates over 2 Mbps. It is a very flexible encryption unit that supports direct key loading via Key Gun device. Key management and authentication is controlled by the configuration module which allows only authorized users to program the device and change keys.
