In this paper, four new algorithms for improvements of MD5 and SHA-Keyed/Unkeyed MD5 and Keyed/Unkeyed SHA are proposed. We change the mode of ®xed retrieval of the parameters to that of dynamic retrieval of the parameters by applying a mapping between the index phrase and the parameter table. As shown in the experimental result, with 1% degradation of performance, comparing to the original alg...

HADES ist ein im WiN­Labor an der Universität Erlangen entwickeltes System zur Ermittlung qualitätsrelevanter Daten wie IP­Paketlaufzeit und Paketverluste in Computernetzwerken. Gemessene und statistisch bewertete Paketlaufzeiten lassen Rückschlüsse zu, wie die Qualität von Netzwerkverbindungen einzuordnen ist und wo kritische Netzwerksituationen auftreten bzw. auftreten können. In dieser Arbei...

The IETF has developed a one-way packet loss metric that measures the loss rate on a Poisson and Periodic probe streams between two hosts. However, the impact of packet loss on applications is, in general, sensitive not just to the average loss rate but also to the way in which packet losses are distributed in loss episodes (i.e., maximal sets of consecutively lost probe packets). This document...

This paper presents novel evaluation criteria which are used to evaluate the effectiveness of Virginia wineries websites in the following four different dimensions: (1) general features of a website; (2) wine tourism; (3) marketing; and (4) educational. A total of 182 wineries are analyzed by researchers and the Cohen’s Kappa was computed as an inter-reliability test among raters. Using a dicho...
