Nintendo announced today that it has licensed micro and full versions of RSA's BSAFE encryption schemes for use in the DS handheld. Nintendo will use the encryption to protect games when they are played or shared over the DS's Wi-Fi connection, and to prevent gamers from pirating demos. "Nintendo's use of our technology in its portable game console is a great endorsement," said Rick Welch, vice president of developer solutions and professional services at RSA Security. No word yet on when RSA encryption will be implemented in the DS.
