An introduction to the combination of TEX and the scripting language Lua.

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 rst shows that the Jakobsson's MIX net of Eurocrypt'98, which was believed to be resilient and very eecient, is broken. We next propose an eecient t-resilient MIX net with O(t 2) servers in which the cost of ea...

Background: The prevalence of allergic diseases has risen in the last decades. The objective of this study was to determine the common allergens in children via the skin prick test.Methods: This cross-sectional study recruited 313 allergic children (4 months to 18 years old) referred to the Asthma and Allergy Clinic of Children’s Medical Center in Tehran. A questionnaire containing demographic ...

Anonymous communication is useful in variety of online applications. Evoting, online chat software and data collection for surveying are some of the applications where anonymity is an important feature. One way to guarantee anonymous network communication is using a mix network (mix-net) protocol. A mix network is a protocol that contains several mix servers. A mix server collects user’s cipher...

In 14 mongrel dogs, refractory periods were determined in nonischemic and acutely ischemic zones of myocardium during control conditions, 15 minutes after coronary ligation, and 10 and 20 minutes after a procainamide infusion. Following coronary ligation, refractory periods in the nonischemic area remained unchanged (100.8% of control) while in the ischemia area they decreased to 88.6% of contr...

In this paper we present a protocol for unlinkable and anonymous communication in multi hop wireless networks. There exist solutions for unlinkable communication in the internet, such as Tor and Mix networks. These protocols need fixed infrastructure and they are prone to traffic analysis attacks, i.e. where an attacker tries to map communicating devices by performing statistical analysis. Wire...

Traditionally, there are two methods to implement anonymous channels: free-route networks like onion routing and cascade networks like mix network. Each of them has its merits and is suitable for some certain applications of anonymous communication. Both of them have their own drawbacks, so neither of them can satisfy some applications. A third solution to anonymous channels, Klein bottle routi...
