## 2 Related Works  
There has been extensive work, as well as several ongoing works, on the implementation of the PQC algorithm and its variants. In this section, we review some of the existing works and explain the major difference between our paper and such research. Numerous studies have explored the operation [14; 15] and implementation of the PQC KEM algorithm across different hardware platforms. Additionally, most current implementations of the PQC algorithm focus on its integration with Secure Sockets Layer (SSL), Transport Layer Security (TLS) [16; 17; 18], and Secure Shell (SSH). Furthermore, several works on PKE have been conducted, and there is ongoing work on the implementation of PQC algorithms and their variants. In [19], [PERSON] et al. proposed a new multivariate public-key cryptosystem based on permutation p-polynomials over finite fields, focusing on the need for secure and efficient public-key systems that can withstand increasing computing power and quantum computing. [PERSON] et al. [20] proposed a generic transformation that achieves post-quantum security for classical signature schemes by hiding the public key with a one-time use of the key pair. Meanwhile, [PERSON] et al. [21] evaluated the efficiency of the Kyber KEM algorithm in a mobile application, specifically analyzing its performance on the x86 and ARM architectures. In addition, surveys and reviews highlighting the issues and constraints of migrating applications to be PQC-compliant have been carried out. [PERSON] [22] discussed the challenges and research efforts required for migrating applications to PQC due to the vulnerability of current public-key cryptography schemes to quantum computers. [PERSON] et al. [23] surveyed the performance and optimization of PQC algorithms for Internet of Things (IoT) systems. They highlighted the computational cost challenges of PQC algorithms for resource-constrained IoT devices and reviewed recent proposals for optimization. Similarly, [PERSON] [24] presented a comprehensive review of PQC for the IoT, covering both theoretical and practical aspects. [PERSON] et al. [25] reviewed PQC algorithms, focusing on the Kyber algorithm, and discussed the challenges and opportunities of post-quantum security. [PERSON] et al. [26] discussed the need for PQC in light of the threat quantum computing poses to classical encryption schemes. [PERSON] et al. [27] provided a comprehensive introduction to the emerging field of quantum-resistant cryptography, emphasizing its critical importance in safeguarding wireless networks against quantum computing threats. In their paper, they highlighted the vulnerabilities of current cryptographic standards to quantum attacks and explored solutions such as PQC and Quantum Key Distribution (QKD), alongside practical migration strategies like hybrid approaches. They further underscored the role of global standardization efforts, particularly by NIST, in advancing PQC algorithms while addressing challenges in integrating these techniques into existing infrastructures. Despite these varied approaches, the practical application of the PQC algorithm remains confined to the aforementioned protocols and has not expanded to other commonly used applications. Moreover, directly applying PQC algorithms to various applications and systems may lead to performance issues, as many of these have stringent QoS requirements. Therefore, to fully assess the impact of direct PQC algorithm usage on application scenarios within a wireless network, a protocol that allows a PQC algorithm or hybrid mode to be used for securing application data is essential. In addition, unlike in most implementations of PQC algorithms, the design and implementation of our proposed protocols extend beyond the integration of PQC into the traditional TLS/SSH to direct application-layer security and real-world scenarios. The use of a sequence-number-based mechanism to counter replay and MITM attacks provides an additional layer of security in addition to providing robust PQC algorithm protection.
