In the realm of wireless sensor networks (WSNs), preserving data
integrity, privacy, and security against cyberthreats is paramount.
Proxy re-encryption (PRE) plays a pivotal role in ensuring secure
intra-network communication. However, existing PRE solutions
encounter persistent challenges, including processing delays due to
the transfer of substantial data to the proxy for re-encryption and the
computational intensity of asymmetric cryptography. This study
introduces an innovative PRE scheme that is meticulously customized
for WSNs to enhance the secure communication between nodes
within the network and external data server. The proposed PRE
scheme optimizes efficiency by integrating lightweight symmetric
and asymmetric cryptographic techniques, thereby minimizing
computational costs during PRE operations and conserving energy
for resource-constrained nodes. In addition, the scheme incorporates
sophisticated key management and digital certificates to ensure
secure key generation and distribution, which in turn, facilitates
seamless authentication and scalable data sharing among the
entities in WSN. This scheme maintains sensor-node data encryption
and delegates secure re-encryption tasks exclusively to cluster
heads, thereby reinforcing data privacy and integrity.
The results confirm that the proposed PRE scheme significantly
enhances the security, efficiency, and overall network lifetime of
WSNs.
