KAMAKURA, Japan -- Mitsubishi Electric has developed a prototype encryption device that can handle IPsec v2 on 10Gbps Ethernet.
The encryption and decryption units are developments on the company's existing hardware for Gigabit Ethernet and were demonstrated here at Mitsubishi Electric's research and development center.
The company has managed to increase the amount of data that can be processed each second by expanding parallel encryption of data packets inside the device, said Shinobu Ushirozawa manager of the network security architecture team at Mitsubishi Electric's network security technology department. This was the bottleneck preventing faster speeds, but with 50 parallel data processing units 10Gbps Ethernet is supported.
Four encryption algorithms -- AES, Camellia, MISTY and 3DES -- can be handled by the device and two authentication algorithms -- SHA1 and 256-bit SHA2 -- are ready, said Ushirozawa.
Mitsubishi Electric has already begun promoting the unit to customers in some industries and is working on an even faster model for 100Gbps networks. Such a device could be available next year, Ushirozawa said.
Also on Thursday the company said it has developed four integrated circuits necessary for 10Gbps fiber-to-the-home networks. Currently broadband Internet connections in Japan use 1Gbps access lines that are typically shared between a handful of houses or apartments but carriers are already looking ahead to a next generation service that increases speeds ten-fold.
To realize such networks the development of several low-cost components is necessary. Among these are the four chips that Mitsubishi Electric showed as samples. There still remains a number of devices to be realized including new lasers and diodes for both the optical line transmission unit used by the carrier and the optical network unit in the consumer's home. Mitsubishi Electric engineers estimate developments over the next few years will lead to commercialization of 10Gbps fiber-to-the-home in Japan around 2010.
