In Vehicular Ad Hoc Networks (VANETs), vehicles should report events to warn the drivers of unexpected hazards on the roads. While these reports can contribute to safer driving, VANETs suffer from various security threats; a major one is Sybil attacks. In these attacks, an individual attacker can pretend as several vehicles that report a false event. In this paper, we propose a secure event-rep...

This survey paper studies recent advances in the field of LeakageResilient Cryptography. This booming area is concerned with the design of cryptographic primitives resistant to arbitrary side-channel attacks, where an attacker can repeatedly and adaptively learn information about the secret key, subject only to the constraint that the overall amount of such information is bounded by some parame...

Leakage resilient cryptography aims to address the issue of inadvertent and unexpected information leakages from physical cryptographic implementations. At Asiacrypt 2010, E.Kiltz et al. [1] presented a multiplicatively blinded version of ElGamal public-key encryption scheme, which is proved to be leakage resilient in the generic group model against roughly 0.50*log(p) bits of arbitrary, advers...

Reclaimed asphalt pavement (RAP) is one of the waste materials that highway agencies promote to use in new construction or rehabilitation of highways pavement. Since the use of RAP can affect the resilient modulus and other structural properties of flexible pavement layers, this paper aims to employ two different artificial neural network (ANN) models for modeling and evaluating the effects of ...

In this paper we describe how to use a secret bug as a trapdoor to design trapped ellliptic curve E(Fp). This trapdoor can be used to mount an invalid curve attack on E(Fp). E(Fp) is designed to respect all ECC security criteria (prime order, high twist order, etc.) but for a secret exponent the point is projected on another unsecure curve. We show how to use this trap with a particular type of...

Key establishment in sensor networks is a challenging task, due to the physical constraints of sensor devices and their exposure to several threats. Existing protocols based on symmetric cryptography are very efficient but they are weak against several node impersonation and insider attacks. On the other hand, asymmetric protocols are resilient to such attacks but unfortunately, they are not fe...

The onion routing (OR) network Tor provides anonymity to its users by routing their encrypted traffic through three proxies (or nodes). The key cryptographic challenge, here, is to establish symmetric session keys using a secure key exchange between the anonymous user and the selected nodes. The Tor network currently employs a one-way authenticated key exchange (1W-AKE) protocol ntor for this p...
