Let E be an elliptic curve over the rationals. A crucial step in determining a Mordell-Weil basis for E is to exhibit some positive lower bound > 0 for the canonical height ^h ...
Abstract. Essentially all subexponential time algorithms for the discrete logarithm problem over nite elds are based on the index calculus idea. In proposing cryptosystems based on...
In this paper we produce a practical and efficient algorithm to find a decomposition of type n = k i=1 2si 3ti , si, ti ∈ N ∪ {0} with k ≤ c + o(1) ¡ log n log log n ....
Abstract. The Real-Time Calculus (RTC) [16] is a framework to analyze heterogeneous real-time systems that process event streams of data. The streams are characterized by pairs of ...
