3DES Weakness

NYT-Markoff reports today on Biham and Knudsen's paper on 3DES weakness, "Cryptanalysis of the ANSI X9.52 CBCM Mode," noted here a few days ago. The ANSI X9.F1 committee has held up implementing its standard as a result, and may have to wait for AES. Credit is given to the worldwide DES crack. http://www.nytimes.com See a mirror: http://jya.com/3des-weak.htm Get the Biham/Knudsen paper: http://www.cs.technion.ac.il/%7Ebiham/publications.html
