Now it's safe to let Wi-Fi out to play

摘要

Last year, a man was arrested in London for accessing the internet via someone else's wireless connection. Now "borrowing" a stranger's Wi-Fi could become the norm, and might even be encouraged. Jon Crowcroft and Nishanth Sastry at the University of Cambridge have developed a "wireless cooperative" that allows people to share their Wi-Fi connection with strangers, securely and at no extra cost. It could enable cities to provide free, secure Wi-Fi coverage without needing to invest in expensive infrastructure.
