ABSTRACT
Secure data transmission is a critical
issue for wireless sensor networks (WSNs).Clustering is an effective and
practical way to enhance the system performance of WSNs. In this paper, we
study a secure data transmission for cluster-based WSNs (CWSNs), where the clusters
are formed dynamically and periodically. We propose two Secure and Efficient
data Transmission (SET) protocols for CWSNs, called SET-IBS and SET-IBOOS, by
using the Identity-Based digital Signature (IBS) scheme and the Identity-Based
Online/Offline digital Signature (IBOOS) scheme, respectively. In SET-IBS,
security relies on the hardness of the Diffie-Hellman problem in the pairing
domain. SET-IBOOS further reduces the computational overhead for protocol
security, which is crucial for WSNs, while its security relies on the hardness
of the discrete logarithm problem. We show the feasibility of the SET-IBS and
SET-IBOOS protocols with respect to the security requirements and security
analysis against various attacks. The calculations and simulations are provided
to ] illustrate the efficiency of the proposed protocols. The results show
that, the proposed protocols have better performance than the existing secure
protocols for CWSNs, in terms of security overhead and energy consumption.
Existing System
In this Existing System of wireless sensor network comprised of spatially
distributed devices using wireless sensor nodes to monitor physical or
environmental conditions, such as sound, temperature, and motion. The
individual nodes are capable of sensing their environments, processing the information
data locally, and sending data to one or more collection points in a WSN.
Efficient data transmission is one of the most important
issues for WSNs. Meanwhile, many WSNs are deployed in harsh, neglected and
often adversarial physical environments for certain applications, such as
military domains and sensing tasks with trustless surroundings
Proposed System
In this Proposed System, Secure and efficient data transmission is thus especially
necessary and is demanded in many such practical WSNs. So, we propose two
Secure and Efficient data Transmission (SET) protocols for CWSNs, called SET-IBS
and SET-IBOOS, by using the Identity-Based digital Signature (IBS) scheme and
the Identity-Based Online/Offline digital Signature (IBOOS) scheme,
respectively.
It has been
proposed in order to reduce the computation and storage costs to authenticate
the encrypted sensed data, by applying digital signatures to message packets, which
are efficient in communication and applying the key
management for security.
In the proposed
protocols pairing parameters are distributed and preloaded in all sensor nodes
by the BS initially.

Modules Description
SET Protocol
In
this module, Secure and Efficient data Transmission (SET) protocol for CWSNs. The
SET-IBOOS protocol is designed with the same purpose and scenarios for CWSNs
with higher efficiency.
The proposed SET-IBOOS operates similarly to the previous SETIBS, which has a
protocol initialization prior to the network deployment and operates in rounds
during communication. We first introduce the protocol initialization, then
describe the key management of the protocol by using the IBOOS scheme, and the
protocol operations afterwards.
Key management for security
In
this module, security is based on the DLP in the multiplicative group. The corresponding
private pairing parameters are preloaded in the sensor nodes during the
protocol initialization. The IBOOS scheme in the proposed SET-IBOOS consists of
following four operations, extraction, offline signing, online signing and verifications.
Key management
In this Module, the
key cryptographies used in the protocol to achieve secure data transmission,
which consist of symmetric and asymmetric key based security. • Neighborhood
authentication
In this module,
used for secure access and data transmission to nearby sensor nodes, by
authenticating with each other. Here, “limited” means the probability of neighborhood
authentication, where only the nodes with the shared pairwise key can
authenticate each other.
Storage cost
In this module,
represents the requirement of the security keys stored in sensor node’s memory.
Network scalability
In this module, indicates
whether a security protocol is able to scale without compromising the security
requirements. Here, “comparative low” means that, compared with SET-IBS and
SET-IBOOS, in the secure data transmission with a symmetric key management, the
larger network scale increases, the more orphan nodes appear in the network.
Communication overhead
In this module,
the security overhead in the data packets during communication. • Computational overhead
In this module,
the energy cost and computation efficiency on the generation and verifications of the
certificates or signatures for security.
Attack resilience
In this module,
the types of attacks that security protocol can protect against.
