PROGRAM 


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.: 
William Verspaandonk (Militaire Inlichtingen- en Veiligheidsdienst, Den Haag), 
Steganalysis - The Art of Detecting. 


12.30 - 14.00 hrs.: Lunch break (lunch not included). 


14.00 - 14.45 hrs.: 
Serge Fehr (Centrum voor Wiskunde en Informatica, Amsterdam), 
Black-box secret sharing from primitive sets in number fields. 


14.45 - 15.00 hrs.: Coffee/tea. 


15.00 - 15.45 hrs.: 
Toons Segers (Boston Consultancy Group, Amsterdam), 
Algebraic Attacks from a Gröbner Basis Perspective.
