Enhanced pairing‐free identity‐based broadcast authentication protocol in WSN using ElGamal ECC

Abstract

Authentication among the various communicating devices within wireless sensor networks during broadcasting is most significant among the other primary security services. This authentication during broadcasting services allows multiple mobile end-devices to transmit messages dynamically and securely for fasten consumer tracking and sustaining privacy of the data transferred in the insecure sensor network. To enhance this authentication protocol for secure end-users message distribution, this research work has introduced a novel identity (ID) based cryptographic technique that employs ElGmal-elliptic-curve cryptography and digital signature without implementing bilinear paring operation to reduce huge burden of computation overhead. Additionally, to accelerate the performance of the proposed authentication protocol, the size of the signature along with the encryption key is minimized. Eventually, the authentication protocol provides comparatively less computational complexity with secure and faster key management. The performance analysis supports the aforesaid claim as well as reflects the supremacy of the proposed scheme over the handover authentication protocol and bilinear pairings based authentication schemes.

Confidential Certified Notification Protocol Using Rejectable Soulbound Tokens and Identity-Based Cryptography

“…Identity-Based Cryptography has been already used in different solutions, like to make high-security multicasting in wireless sensor networks [29], to enhance authentication among the various communicating devices within wireless sensor networks during broadcasting for secure end-users message distribution [30], or to overcome the key management issue but still guarantee security even when attackers corrupt the keys, extending the FS-PEKS scheme (Lattice-Based Forward Secure Public-Key Encryption with Keyword Search) [31].…”

Digital signature algorithm based on ElGamal, Diffie-Hellman protocol and the number π

“…This research proposes an algorithm to digitally sign sensitive messages, using the ElGamal cryptosystem called Digital signature algorithm based on ElGamal, Diffie-Hellman protocol and the number π (DSAπ). It is mentioned that using the Diffie-Hellman protocol it is possible to construct a common key, both for the sender and the recipient: [1] performed an authentication between communication devices using an identifier based on ElGamal, the elliptic curve and the signature digital, which as a result, reduced computational complexity and facilitates key management; Similarly, [2] proposed a hybrid algorithm integrating Diffie-Hellman algorithm and Delta Encoding technique (Newton Forward and Backward Interpolation); [3] highlights the advantages of key management with Diffie Hellman algorithms, where an image encryption algorithm with seed-generated keys was proposed. Several systems have been developed with different approaches to sign messages in order to verify the authentication of these [4,5].…”
