NEC Electronics Corp. and its subsidiary in Europe, NEC Electronics (Europe) GmbH introduced a software for microcontrollers (MCUs) that detects counterfeit battery products in mobile phones and digital still camera batteries.

The software offers performance benefits by utilizing the CIPHERUNICORN-S technology from NEC Corp., which operates at processing speeds up to 18 times faster and requires 80 percent less memory than standard encryption technology. According to NEC, the improved performance reduces hardware requirements and enables the software to be used with standard 8-bit MCUs, which in turn leads to lower overall costs.

"The growing number of worldwide incidences involving inferior counterfeit batteries is a considerable source of concern for manufacturers and customers alike," said Kazuo Nakamura, GM of Device SI Division, NEC Electronics. "The authentication software offers a highly effective yet affordable solution to help detect such unauthorized products and prevent the damage caused by them."

The software also offers robust protection against cache attacks (a recent decryption method that measures minute changes in processing times when information stored in the cache memory is accessed) by utilizing the latest algorithms. In addition to being compatible with NEC Electronics' 8-bit 78K0/78K0S MCU family, the software can also be configured for use with third party products by customer request.

The software will be introduced in Japanese digital cameras by year's end and is expected to be used in 50 million units by 2007.
