On the negative side, we show that combinatorially Voronoi cells for arbitrary strictly convex and smooth norms are much more complicated than in the Euclidean case.In particular, we construct a family of three-dimensional lattices whose number of Voronoi-relevant vectors with respect to the l_3-norm is unbounded.Since the algorithm of Micciancio and Voulgaris and its run time analysis crucially dependonthefactthatfortheEuclidean normthenumber of Voronoi-relevant vectors is single exponential in the lattice dimension, this indicates that the techniques of Micciancio and Voulgaris cannot be extended to achieve deterministic single exponential time algorithms for lattice problems with respect to arbitrary l_p-norms."}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":1231102,"access_level":"closed","file_name":"233-1512.00720v1.pdf","file_id":"1501","date_updated":"2018-03-21T10:30:18Z","date_created":"2018-03-21T10:30:18Z","creator":"florida"}],"status":"public"},{"department":[{"_id":"64"}],"user_id":"25078","_id":"2866","type":"bachelorsthesis","status":"public","supervisor":[{"id":"23","full_name":"Blömer, Johannes","last_name":"Blömer","first_name":"Johannes"}],"date_created":"2018-05-24T13:08:41Z","author":[{"first_name":"Felix","full_name":"Biermeier, Felix","last_name":"Biermeier"}],"date_updated":"2022-01-06T06:58:13Z","title":"Untersuchung des Erreichbarkeitsproblems in ungerichteten Graphen bezüglich den Komplexitätsklassen L und SL","citation":{"apa":"Biermeier, F.

Interestingly, none of these have been practically evaluated. We accomplished this task and prove that fault attacks against pairing-based cryptography are indeed possible and are even practical — thus posing a serious threat. Moreover, we successfully conducted a second-order fault attack against an open source implementation of the eta pairing on an AVR XMEGA A1. We injected the first fault into the computation of the Miller Algorithm and applied the second fault to skip the final exponentiation completely. We introduce a low-cost setup that allowed us to generate multiple independent faults in one computation. The setup implements these faults by clock glitches which induce instruction skips. With this setup we conducted the first practical fault attack against a complete pairing computation.","lang":"eng"}],"type":"conference","publication":"Proceedings of Fault Tolerance and Diagnosis in Cryptography(FDTC)","doi":"10.1109/FDTC.2014.22","title":"A Practical Second-Order Fault Attack against a Real-World Pairing Implementation","date_created":"2017-10-17T12:42:22Z","author":[{"full_name":"Blömer, Johannes","id":"23","last_name":"Blömer","first_name":"Johannes"},{"full_name":"Gomes da Silva, Ricardo","last_name":"Gomes da Silva","first_name":"Ricardo"},{"last_name":"Günther","full_name":"Günther, Peter","first_name":"Peter"},{"last_name":"Krämer","full_name":"Krämer, Juliane","first_name":"Juliane"},{"first_name":"Jean-Pierre","last_name":"Seifert","full_name":"Seifert, Jean-Pierre"}],"date_updated":"2022-01-06T07:01:16Z","citation":{"ama":"Blömer J, Gomes da Silva R, Günther P, Krämer J, Seifert J-P.
