This document proposes two secure data transmission protocols for cluster-based wireless sensor networks called SET-IBS and SET-IBOOS. SET-IBS relies on the Diffie-Hellman problem for security, while SET-IBOOS relies on the discrete logarithm problem. The protocols aim to securely and efficiently transmit sensor data to base stations while improving on existing protocols by reducing computational overhead and energy consumption through clustering and dynamic routing techniques. Evaluation of the protocols demonstrates their effectiveness compared to other secure clustering methods for wireless sensor networks.

WSNs

3. CLUSTERING AND COMPONENTS
What is Clustering in WSNs?
The process of organizing objects into groups whose members are
similar in some way.
• Reduce routing table size. Conserve communication bandwidth. Avoids
redundant message exchanges.
• Cluster head can aggregate data. Clusters can schedule activities so sensors
can sleep.
 Why Clustering?

6. • Secure data transmission is a critical issue for wireless sensor networks,
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.
• In SET-IBS, security relies on the hardness of the Diffie-Hellman problem
in the pairing domain.
• SET-IBOOS its security relies on the hardness of the discrete logarithm
problem.
ABSTRACT

7. • 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.
• 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.
• Secure and efficient data transmission is thus especially necessary
and is demanded in many such practical WSNs.

• There is no fixed routing path with less energy
Consumption.
• The routing technique is Flooding.

9. TWO SECURE DATA TRANSMISSION
PROTOCOLS
• SET-IBS
secure and efficient data transmission by using the
identity-based digital signature.
• SET-IBOOS
secure and efficient data transmission by using the
identity-based online/offline digital signature.

10.  SET-IBS
• Security relies on the hardness of the Diffie-Hellman problem in the
pairing domain.
• D-H is a method of digital encryption that uses numbers raised to
specific powers to produce decryption keys on the basis of
components that are never directly transmitted.

11.  SET-IBOOS
• Security relies on the hardness of the discrete logarithm
problem.
• Reduces the computational overhead for protocol
security, which is crucial for WSNs.
