We apply blind source separation techniques from statistical signal processing to separate the traffic in a mix network into either individual flows or groups of flows. This separation requires no a priori information about the individual flows. As a result, unlinkability can be compromised without ever observing individual flows. Our experiments show that this attack is effective and scalable....

We introduce a new payment architecture that limits the power of an attacker while providing the honest user with privacy. Our proposed method defends against all known attacks on the bank, implements revocable privacy, and results in an efficient scheme which is well-suited for smartcard-based payment schemes over the Internet.

Abstract The widespread occurrence of nouns in one language with a determiner the other, often referred to as mixed NPs, has generated much theorizing and debate. Since both syntactic account based on abstract features an highlighting notion Matrix yield largely same predictions, we assess how tenets each play out speaker choices. data derive from massive corpus spontaneous nominal mixes, produ...

INTRODUCTION The prevalence of atopic diseases has increased in recent decades dramatically. The most common aeroallergens in Northeastern Iran have not been fully defined. Determining 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 1-8...

Genes encoding three putative endopeptidases were identified from a draft-quality genome sequence of Lactobacillus helveticus CNRZ32 and designated pepO3, pepF, and pepE2. The ability of cell extracts from Escherichia coli DH5alpha derivatives expressing CNRZ32 endopeptidases PepE, PepE2, PepF, PepO, PepO2, and PepO3 to hydrolyze the model bitter peptides, beta-casein (beta-CN) (f193-209) and a...

We introduce a robust and efficient mix-network for exponentiation, and use it to obtain a threshold decryption mix-network for ElGamal encrypted messages, in which mix servers do not need to trust each other for the correctness of the result. If a subset of mix servers cheat, they will be caught with an overwhelming probability, and the decryption can restart after replacing them, in a fashion...
