The Comparative Method: Simplicity + Power = Results

EGO: Controlling the Power of Simplicity

The SELF programming language provides powerful dynamic features, allowing programmers to add and remove methods from objects and to change the inheritance hierarchy at run time. These facilities are useful for modeling objects that behave in different ways at different points in the object’s lifecycle. Unstructured use of these techniques, however, can result in arbitrary changes to the interf...

Simplicity of skew generalized power series rings

A skew generalized power series ring R[[S, ω]] consists of all functions from a strictly ordered monoid S to a ring R whose support contains neither infinite descending chains nor infinite antichains, with pointwise addition, and with multiplication given by convolution twisted by an action ω of the monoid S on the ring R. Special cases of the skew generalized power series ring construction are...

Smartly Analyzing the Simplicity and the Power of Simple Power Analysis on Smartcards

A new kind of cryptanalytic attacks, targeted directly at the weaknesses of a cryptographic algorithm’s physical implementation, has recently attracted great attention. Examples are timing, glitch, or power-analysis attacks. Whereas in so-called simple power analysis (SPA for short) only the power consumption of the device is analyzed, differential power analysis (DPA) additionally requires kno...
