Post Quantum solutions for security protocols

In an era where data security is an indispensable priority, the evolution of security protocols is crucial to ensure the protection of digital communica- tions. This study focuses on integrating post-quantum solutions into the Transport Layer Security (TLS) security protocol to mitigate vulnerabilities associated with the advent of quantum computers that could lead to the break of our security protocols. The TLS protocol represents a critical standard for ensuring confiden- tiality and integrity of communications over the Internet. However, its ro- bustness has been questioned by the increasing computing power of quantum computers, which could compromise the cryptographic algorithms tradition- ally used by TLS. This research work proposes an innovative modification of the TLS hand- shake algorithm, introducing post-quantum cryptography mechanisms to ensure enhanced security in the era of quantum computers. Implementing such post-quantum solutions within the TLS protocol offers robust protec- tion against cryptographic attacks based on quantum algorithms. Through a detailed analysis of performance and security, this thesis demon- strates the effectiveness of post-quantum solutions in increasing the resilience of the TLS protocol against advanced threats. The results obtained provide a solid start for integrating these emerging technologies into cybersecurity systems, while also ensuring the protection of sensitive data in an increas- ingly complex and threatening digital landscape.
