A pervasive identification service for physical access control

In pervasive environments managing people access control to physical places through their digital identity and simple, uniform, non-invasive yet secure mechanisms, is certainly an important issue. We face this problem by proposing a new secure one-time-password approach with peculiar features of efficiency making it very suitable for the considered application. This aspect is indeed particularly important in pervasive setting, where portable devices are used at any time and anywhere, making the power consumption aspect strongly critical.
