In 2003, Fischlin introduced the concept of progressive verification in cryptography to relate error probability a cryptographic procedure its running time. It ensures that verifier confidence validity grows with work it invests computation. Le, Kelkar and Kate recently revisited this approach for digital signatures proposed similar framework under name flexible signatures. We propose efficient...

With the increasing number of bicycle riders, there is an increased risk of accidents between bicycles and automobiles. Some accidents are caused by speeding bicycles and the lack of communication between the cyclist and car drivers. To close the communication gap, we propose a method to detect speeding behaviors using a conventional smartphone. Using the smartphone, the cyclist will be able to...
