TLDR
The analytical and OMNET++ simulation results of the proposed scheme shows that it provides better network connectivity, consume less memory and has better network resilience against attacks.Abstract:
The use of Wireless Sensor Networks (WSNs) has got great importance in many applications ranging from home and industrial applications to more sensitive military applications. In mobility context, such applications introduce new technological challenges for security. The resource constrained devices should be protected from various security attacks and provided with secure data communication. To this aim, a proper key management scheme supporting node mobility is required. In this paper, we present an effective key management scheme that can support node mobility in the heterogeneous sensor networks that consists of mobile sensor nodes with few fixed sensor nodes. The analytical and OMNET++ simulation results of our proposed scheme shows that it provides better network connectivity, consume less memory and has better network resilience against attacks.read more

An energy and memory-efficient key management scheme for mobile heterogeneous sensor networks
TL;DR: This paper presents an effective mutual authentication and key establishment scheme for heterogeneous sensor networks consisting of numerous mobile sensor nodes and only a few more powerful fixed sensor nodes that assures better network connectivity, consumes less memory, has low communication overhead during the authentication andKey establishment phase and has better network resilience against mobile nodes attacks.

Privacy-preserving data aggregation in two-tiered wireless sensor networks with mobile nodes.
TL;DR: This paper focuses on the SUM aggregation function and proposes two privacy-preserving data aggregation protocols for two-tiered sensor networks with mobile nodes: PDAAS and PDACAS, which can protect the privacy of sensor nodes even the aggregator and the sink collude, at the cost of a little more overhead.

The capacity of wireless networks
Piyush Gupta,P. R. Kumar +1 more
TL;DR: When n identical randomly located nodes, each capable of transmitting at W bits per second and using a fixed range, form a wireless network, the throughput /spl lambda/(n) obtainable by each node for a randomly chosen destination is /spl Theta/(W//spl radic/(nlogn)) bits persecond under a noninterference protocol.

A key-management scheme for distributed sensor networks
TL;DR: A key-management scheme designed to satisfy both operational and security requirements of DSNs is presented, which relies on probabilistic key sharing among the nodes of a random graph and uses simple protocols for shared-key discovery and path-key establishment, and for key revocation, re-keying, and incremental addition of nodes.

Random key predistribution schemes for sensor networks
TL;DR: The random-pairwise keys scheme is presented, which perfectly preserves the secrecy of the rest of the network when any node is captured, and also enables node-to-node authentication and quorum-based revocation.
Digitalized signatures and public-key functions as intractable as factorization
TL;DR: It is proved that for any given n, if the authors can invert the function y = E (x1) for even a small percentage of the values y then they can factor n, which seems to be the first proved result of this kind.

Perfectly-Secure Key Distribution for Dynamic Conferences
TL;DR: This paper considers the model where interaction is allowed in the common key computation phase, and shows a gap between the models by exhibiting an interactive scheme in which the user's information is only k + t - 1 times the size of the commonKey.
