We describe a design for a reputation system that increases the reliability and thus efficiency of remailer services. Our reputation system uses a MIX-net in which MIXes give receipts for intermediate messages. Together with a set of witnesses, these receipts allow senders to verify the correctness of each MIX and prove misbehavior to the witnesses. We suggest a simple model and metric for eval...

The language MIX consists of all strings over the three-letter alphabet {a, b, c} that contain an equal number of occurrences of each letter. We prove Joshi’s (1985) conjecture that MIX is not a tree-adjoining language.

Background: Because of geographic variation and regional types of allergens, it is recommended that allergists identify common allergens in their area of activity. In the present study, the prevalence of respiratory allergens in patients with asthma and allergic rhinitis was investigated. Methods: This study is descriptive and retrospective. The required data of this study were extracted from ...

In this paper we present eFarnel, a new electronic voting scheme based on the paper-based Farnel protocol. The new scheme corrects problems observed in previous proposes to simulate Farnel electronically. Moreover, we also define a new kind of mix net, called F-Mix-Net, which is required by our protocol.

A MIX net takes a list of ciphertexts (c1; ; cN) and outputs a permuted list of the plaintexts (m1; ; mN) without revealing the relationship between (c1; ; cN) and (m1; ; mN). This paper shows that the Jakobsson's ash MIX of PODC'99, which was believed to be the most eecient robust MIX net, is broken. The rst MIX server can prevent computing the correct output with probability 1 in our attack. ...

Introduction:The prevalence of atopic diseases has increased in recent decades dramatically. The most common aeroallergens in Northeastern Iran have not been fully defined. Define the most common aeroallergens in allergic patients based on the skin prick test (SPT) was aimed in this investigation.Materials and Methods:This cross-sectional study enrolled 1,006 allergic patients (aged 1–86 years)...

multiple sclerosis (ms) and allergy are believed to up regulate t helper cell type 1 (th1) and t helper cell type 2 (th2) responses, respectively. it has been shown that disequilibrium in the  ratio  of  th1/th2  activities may increase frequency of  one  disease and  decrease the frequency of the other. the aim of this study was to investigate the relation of ms with allergy and atopy in new d...

We propose a new mix network that is optimized to produce a correct output very fast when all mix servers execute the mixing protocol correctly (the usual case). Our mix network only produces an output if no server cheats. However, in the rare case when one or several mix servers cheat, we convert the inputs to a format that allows “back-up” mixing. This back-up mixing can be implemented using ...
