Abstract:
Cryptography, which is the practice of securing information by converting it into
a form that is unintelligible to unauthorized individuals, is widely recognized as one of the
most effective technologies for enhancing the security of Wireless Sensor Networks (WSNs).
In this particular research endeavor, the authors introduce and elucidate upon the Three Phase
Hybrid Cryptographic (TPHC) algorithm, a novel approach that combines both symmetric and
asymmetric cryptographic algorithms to achieve the desired security objectives. By
incorporating well-established encryption techniques such as Advanced Encryption Standard
(AES), Data Encryption Standard (DES), and a modified version of the Rivest-Shamir-
Adleman (RSA) algorithm, TPHC is able to provide both confidentiality and authentication for
the transmitted data within the WSN. Moreover, to ensure the integrity of the information,
TPHC is complemented with a distinctive hashing algorithm that is specifically designed for
this purpose. This proposed hash function exhibits adherence to the fundamental properties of
conventional hashing, namely, one-wayness, second pre-image resistance, collision resistance,
and the avalanche effect. The empirical results of this investigation unequivocally establish the
dominance of the TPHC technique in comparison to the current WSN algorithm across multiple
performance measures, such as computation time, size of encrypted data, size of digested data,
and energy utilization.
