We determine the imbalances of the keystreams produced by Achterbahn-80 and Achterbahn-128 in two different ways. The number of cyclically inequivalent keystreams produced by the keystream generators of Achterbahn-80 and Achterbahn-128 is determined. An abstract model for the keystream generator of a primitive NLFSR combination generator is used to justify the correlation attack introduced in [...

Earlier it has been reported that there exist correlation attacks on RC6 with 128-bit blocks with a reduced number of rounds. In this note it is investigated how well RC6 with 256-bit blocks resists such attacks.

In many pairing-based protocols often the evaluation of the product of many pairing evaluations is required. In this paper we consider methods to compute such products efficiently. Focusing on pairingfriendly fields in particular, we evaluate methods for the Weil, Tate and Ate pairing algorithms for ordinary elliptic curves at various security levels. Our operation counts indicate that the mini...

Abstract Introduction In the UK, forgotten ureteric stents are considered a ‘never event’ and hence can be source of significant litigation. Forgotten stent was most frequent postoperativerelated claim over 14 years in 2011. Aim To assess possible risk factors for missing an antegrade (AG) patient. Method Retrospective data collection from Interventional radiology (IR) department: 1. Date AG in...
