I recently put the foils of a course `Intro to Cryptography with applications to e-commerce` in http://www.hrl.il.ibm.com/mpay/course/course.html. You `buy` the lectures using our IBM Micro Payments demo. Some of you had problems downloading the foils, usually using non-windows machines. We've added `wallet server` support so now your don't have to install our wallet (you can still install it to get one-click access, if you use windows). Also, I've added two more lectures: -- A set of foils on `Payments for Internet and Mobile Commerce (Overview)` -- A paper on `Overview of Security and Payments for Mobile Commerce` Feedback welcome (on the lectures and overview as well as on our projects). Please forward this informations to others who may be intersted. Best Regards, Amir Herzberg IBM Research Lab in Haifa (Tel Aviv Office) http://www.hrl.il.ibm.com
