[net.crypt] More Leaky Knapsacks

outer@utcsrgv.UUCP (Richard Outerbridge) (09/22/83)

Some more knapsack-weakness references that have just come my way:

Beth, Thomas, Ed. CRYPTOGRAPHY Lecture Notes in Computer Science #149,
	(New York: Springer-Verlag, 1983).  Proceedings of the Workshop
	on Cryptography, Burg Feuerstein, Germany, March 29 - April 2, 1982.
Compiled from papers presented prior to the Shamir-Adleman breakthroughs,
this book includes two papers that point towards the weakspot.  They are:
	Ingemarsson, I. "A New Algorithm for the Solution of the Knapsack
		Problem", pp309-315.
and	Eier, R. and Lagger, H. "Trapdoors in Knapsack Cryptosystems", 
		pp316-322.

There is also a section devoted to analysis and applications of the RSA
scheme.  One of the articles is in German; there is an English abstract 
by one of the authors which "presents a new factoring algorithm [for
numbers meeting certain criteria, but].....So far it is unpredictable
which integers n satisfy these conditions."
