Tor proteins, homologous to DNA-dependent protein kinases, participate in a signal transduction pathway in yeast that regulates protein synthesis and cell wall expansion in response to nutrient availability. The anti-inflammatory drug rapamycin inhibits yeast cell growth by inhibiting Tor protein signaling. This leads to diminished association of a protein, Tap42, with two different protein pho...
Tor is susceptible to traffic correlation attacks in which an adversary who observes flows entering and leaving the anonymity network can apply statistical techniques to correlate flows and de-anonymize their endpoints. While an adversary may not be naturally positioned to conduct such attacks, a recent study shows that the Internet’s control-plane can be manipulated to increase an adversary’s ...
In 2013, more than half a million users relied on Tor, the second generation Onion Routing system, daily to protect their privacy [1]. Users hide among other users in the Tor network to achieve anonymity, so the degree of anonymity grows as more users successfully participate in the network [3]. A user who makes mistakes while installing or using Tor software jeopardizes both her own privacy an...
Tap42/α4, a regulatory subunit of protein phosphatase 2A, is a downstream effector of the target of rapamycin (TOR) protein kinase, which regulates cell growth in coordination with nutrient and environmental conditions in yeast and mammals. In this study, we characterized the functions and phosphatase regulation of plant Tap46. Depletion of Tap46 resulted in growth arrest and acute plant death ...
The Torso (Tor) signaling pathway activates tailless (tll) expression by relieving tll repression. None of the repressors identified so far, such as Capicuo, Groucho and Tramtrack69 (Ttk69), bind to the tor response element (tor-RE) or fully elucidate tll repression. In this study, an expanded tll expression pattern was shown in embryos with reduced heat shock factor (hsf) and Trithorax-like (T...
Tor is a real-world, circuit-based low-latency anonymous communication network, supporting TCP applications over the Internet. In this paper, we present an extensive study of protocol-level attacks against Tor. Different from existing attacks, the attacks investigated in this paper can confirm anonymous communication relationships quickly and accurately by manipulating one single cell and pose ...
Tor is a widely used anonymity network providing low-latency communication capabilities. Around 400,000 users per day use Tor to route TCP traffic through a sequence of relays; three hops are selected from a pool of currently almost 3000 volunteer-operated Tor relays to comprise a route through the network for a limited time. In comparison to single-hop proxies, forwarding TCP streams through m...
The expected cell latency for multi-hop M/D/1 queueing networks in Wardrop equilibrium is calculated. load balanced such that no user can benefit from unilaterally changing its routes. results are applied to a typical snapshot of the Tor anonymity network, which an efficient approach devised calculate routing strategy. For this snapshot, numerically compared with globally optimal and original m...
As sessile organisms, plants must adapt to variations in the environment. Environmental stress triggers various responses, including growth inhibition, mediated by the plant hormone abscisic acid (ABA). The mechanisms that integrate stress responses with growth are poorly understood. Here, we discovered that the Target of Rapamycin (TOR) kinase phosphorylates PYL ABA receptors at a conserved se...
We introduce an attack against encrypted web traffic passing over the first hop – between client and Tor gateway – of the Tor network. The attack makes use only of packet timing information on the uplink and so is impervious to packet padding defences. In addition, we show that the attack is robust against the randomised routing used in Tor. We demonstrate the effectiveness of the attack at ide...
