In Ad Hoc networks it is very difficult to gain the same security as wired networks without the support of infrastructure. To save network's resources, a group key agreement method using ECDH (elliptic curve Diffie-Helleman) based on GDH.3 (group Diffie-Hellman) protocol is presented, replacing original Diffie-Hellman in GDH.3. Using ECDH in GDH.3 does not(More)

The specific characteristics of Mobile Ad Hoc Networks (MANETs) make secure transmission important issues in its research. In this paper, we present a scheme using soft encryption combined with multipath routing to provide security of data transmission over MANETs. In the scheme, the messages are divided into different parts and encrypted by simple(More)

In mobile ad hoc networks, routing security has become an important issue. Due to limited bandwidth and batteries energy of ad hoc networks, routing protocols of ad hoc must be secure, effective and less redundancy. This makes it possible for analyzing the security performance of routing protocols via formal analysis. In this paper, we describe the(More)
Recently, 60 GHz technology has become a promising alternative for indoor positioning systems because it can provide very accurate temporal and spatial information for precise time of arrival (TOA) estimation. However, non-line-of-sight (NLOS) propagation in indoor environments can significantly degrade the localization accuracy with 60 GHz signals. To(More)
