Some remarks on the Pethö public key cryptosystem. (English) Zbl 0794.94009
Coray, Daniel (ed.) et al., Journées arithmétiques. Exposés présentés aux dix-septièmes congrès à Genève, Suisse, 9-13 septembre 1991. Paris: Société Mathématique de France, Astérisque. 209, 257-264 (1992).
After introducing Pethö’s public key cryptosystem, the author proves under certain assumptions that it can be broken in polynomial time. This implies that the freedom in choice of the parameters must be used to make certain these assumptions are not met.
