Data aggregation has been one of the most widely researched topics for Wireless Sensor Network (WSN) as it helps in increasing the effective life time of the network and reduces the packet transmission overhead. Besides other challenges, security is one of the serious challenges during data aggregation. Numerous solutions on security for data aggregation for WSN are based on homomorphic encryption technique or Elliptic Curve Cryptography (ECC) based solutions and thus are vulnerable to attacks by quantum machines. This paper presents a post-quantum security solution using lattice cryptography. The proposed solution is applying Learning with Errors over Rings (R-LWE) for encryption of data in the data aggregation process at the gateway module of WSN. Security analysis shows that the proposed scheme provides confidentiality, integrity and authenticity during communication. Performance analysis shows that the proposed scheme is lightweight and shows better performance compared to Elliptic Curve Elgamal (ECEG) cryptography based scheme and symmetric homomorphic based scheme.

Wireless sensor networks (WSNs) are quiet dynamic technology made up of discrete multi-function sensor nodes that interconnect wireless for short distances. WSNs have distinct traits as well as limitations that impede the development of efficient attack detection and prevention methods. Security in WSN is a more difficult task because of the processing limits of sensor nodes as well as the nature of wireless communications. The widespread WSNs usage has given development to several forms of threats. To guard against threats, appropriate security measures must be implemented. Cryptography, specifically encryption, plays a pivotal role in protecting data from unauthorized access. However, not all encryption methods are equally effective, as some exhibit vulnerabilities. Elliptic Curve Cryptography (ECC) is the most efficient option because of its reduced key size. Comprehensive safety despite lower key sizes leads to area as well as power efficient crypto systems. With recent technological advancements, traditional encryption no longer appears to be a safe solution for security and privacy of data. Quantum cryptography uses quantum physics processes to provide safe data transmission among sender and recipient. However, quantum cryptography comprises a revolution over network security field. Therefore, this research focuses on Quantum Key Distribution (QKD) with ECC for effective authentication, key management and energy conservation. Thus, the proposed QKD-ECC method is implemented and evaluated with traditional ECC and other cryptography method for better WSN security and privacy of data transmission.

These networks have traits. Face challenges in devising effective strategies for identifying and thwarting attacks due to limitations, in individual sensor node processing power and the essence of wireless communication. Securing WSN poses a challenge given the constrained processing abilities of sensor nodes and the inherent nature of communication while facing various security threats that have emerged alongside the widespread adoption of these networks. To protect against these dangers it's crucial to put in place the security measures Encryption's key, to keeping data safe from unauthorized users Nevertheless not all encryption methods are equally strong as some are vulnerable Elliptic Curve Cryptography (ECC) is considered the best option due to its smaller key sizes offering strong security with efficiency in space and energy As technology advances conventional encryption techniques are seen as inadequate, for ensuring data privacy and security Utilizing principles from physics to ensure data transmission, between the sender and receiver is a groundbreaking advancement in network security known as quantum cryptography. Quantum Key Distribution (QKD) combined with ECC is highlighted in this study, for authentication processes, key management and energy efficiency. A novel method called QKD ECC has been put into practice. Compared against ECC and other encryption methods to bolster the security of WSN and safeguard the confidentiality of data exchange.
Quantum computing poses a significant threat to Wireless Sensor Networks (WSNs) by undermining traditional cryptographic algorithms such as RSA and Elliptic Curve Cryptography (ECC). This work proposes a quantum-safe architecture for WSNs that integrates post-quantum cryptography (PQC) with lightweight IoT protocols to ensure long-term confidentiality, authenticity, and resilience. The framework leverages ML-KEM for key encapsulation and ML-DSA/SLH-DSA for signatures, and seamlessly integrates with EDHOC, OSCORE, and COSE. A novel Efficient Adaptive Parameter Selection (EAPS) mechanism dynamically adjusts cryptographic strength to balance security, energy consumption, and latency under varying network conditions. Experimental evaluation demonstrates that ciphertext fragmentation (8–27 pieces) results in manageable completion times of 4–10 seconds, while join operations consume only 0.005–0.03 J per cryptographic handshake event, while system-level energy consumption including network overhead is higher (~1.0–1.4 J per join cycle depending on hop count and retransmissions). Battery lifetime projections under steady-state sensing workloads range from approximately 115–280 months for low-duty-cycle operation, whereas realistic deployment conditions with periodic communication yield effective lifetimes of 11.5–24 months. Security analysis confirms robust resistance against downgrade attacks and Harvest-Now-Decrypt-Later (HNDL) threats. Moreover, EAPS reduces risk scores by over 50% compared to fixed schemes with less than 10% additional energy overhead, and batch signature verification improves scalability by increasing throughput from ~1,600 to ~2,800 verifications per second. Overall, the proposed framework demonstrates that WSNs can achieve quantum-resistant security with minimal performance trade-offs, ensuring readiness for the post-quantum era.
Wireless Body Sensor Networks (WBSNs) have rapidly developed to allow real-time health monitoring and remote medical diagnostics with better patient care. However, due to the sensitive nature of the data transferred within WBSNs, more integrated security mechanisms are mandatory, especially against possible attacks by both classical and quantum adversaries. The developments in quantum computing may break the conventional encryption schemes, so it is very important to explore quantum-resistant systems. The paper proposes a new scheme for lattice-based high-security authentication in WBSNs. Lattice-based cryptography provides post-quantum security as it has inherent resistance against quantum attacks and assumptions about the hardness of the computational problem, especially the Learning with Errors problem and the SVP. The architecture proposed strengthens defenses against man-in-the-middle, impersonation, and eavesdropping attacks by authenticating and ensuring that a safe key exchange takes place and that data integrity is achieved. It analyzes the performance, security overhead, and energy economy of LBQC to make sure it is appropriate for such low-power, low-resource contexts. The experimental outcomes validate the applicability of this technique, highlighting how well it will protect WBSNs against attacks from methods developed by quantum computing, and, at the same time, the system will remain resilient and the data confidential.

Wireless sensor networks (WSNs) are pervasively employed in critical domains such as smart healthcare, industrial automation, and environmental surveillance, where secure access control is essential. User authentication protocols are vital for thwarting unauthorized intrusions, yet the vast majority of existing schemes rely on conventional public-key cryptography (such as ECC, RSA), which is provably insecure in the post-quantum era due to Shor's algorithm. This motivates the design of post-quantum authentication that is also lightweight for resource-limited sensors. To address this challenge, we propose an efficient authentication and key agreement protocol based on Number Theory Research Unit (NTRU), a lattice-based cryptosystem offering proven resistance to quantum attacks. We have proven the correctness and security of our scheme through BAN logic and random oracle model and demonstrated through informal analysis that our scheme can resist various attack methods and possesses high security features. Moreover, we thoroughly evaluate our protocol against the most recent state-of-the-art schemes. The results indicate that our scheme has the lowest computational cost, and its communication cost is superior to that of most other schemes. Overall, our proposed protocol provides a robust, efficient, and future-proof authentication solution for WSNs, well-suited for deploying WSNs environments.
