10.45 - 11.30 hrs.: 
Benne de Weger (Technische Universiteit Eindhoven), 
Applications of Hash Collisions. 

Abstract: As shown by the recent work of Xiaoyun Wang and co-authors, collisions for MD5 can easily be constructed, and SHA-1 is weaker than we thought. Though these are not second pre-image attacks, some applications are beginning to appear that make people think. One example, to be highlighted in this talk, is the construction of two different valid X.509 certificates with identical signatures. 

11.30 - 11.45 hrs.: Coffee/tea. 

11.45 - 12.30 hrs.:
