Web applications are widely used today. A web application may be vulnerable to session hijacking and cookie theft. In this project, we aim to secure web applications against session hijacking and cookie theft. The proposed system uses quantum cryptography and reverse proxy authentication. Upon successful login to the server, the server generates a session key for the session. The session key is transmitted to the client using Quantum Key Distribution (QKD) protocol so that the session key is kept secret from any third party. The AES or Advanced Encryption Standard, is used to encrypt session cookies. This is done with the help of a session key. Reverse proxy servers authenticate the cookies. They verify whether the cookies are modified or not. If the cookies are not modified, the reverse proxy servers send the cookies to the server. If the cookies are modified, the modified cookies cannot be used for accessing the web application. We can also give the auto login facility to the client by using the encrypted session cookies. The client will not have to re-enter the username and password for accessing the web application. Hence, the proposed system is effective in securing web sessions by using quantum cryptography and reverse proxy authentication.

Secure communication plays a vital role now-a-days. Modern-day secure communication is made possible via cryptography. Modern cryptographic algorithms are based on the process of factoring large integers into their primes, as they are intractable. But the cryptography nowadays is vulnerable to technological advances in computing power like quantum computing and evolution in math to quickly reverse one-way functions like factorization of large integers. Incorporating quantum physics concepts into cryptography is the answer, which results in an assessment of quantum cryptography. A unique type of cryptography known as quantum cryptography makes advantage of quantum mechanics to provide complete protection against the transmitted message. Quantum Key Distribution (QKD), a random binary key distribution used in quantum cryptography, enables communication participants to recognize unauthorized listeners. Quantum Key Distribution (QKD) is likely the most advanced quantum technology currently accessible with full stack systems already in use. This project’s goal is to develop secure and encrypted communication between the parties with the help of a web application using the BB84 protocol.

The rapid growth of digital communication has increased the need for highly secure email systems capable of protecting sensitive information from evolving cyber threats. Traditional encryption techniques such as RSA and ECC are becoming vulnerable due to advancements in quantum computing, which can potentially break conventional cryptographic algorithms. To address these challenges, this project proposes a Quantum Secure Email Client Application that integrates post-quantum cryptography (PQC) techniques to ensure end-to-end secure communication. The proposed system employs quantum-resistant encryption algorithms such as lattice-based cryptography, hash-based signatures, or code-based encryption to secure email content, attachments, and user authentication processes. The email client ensures that messages are encrypted before transmission and can only be decrypted by the intended recipient, thereby preventing unauthorized access, interception, and data leakage. Additionally, the system incorporates secure key exchange mechanisms resistant to quantum attacks, ensuring safe communication even in the presence of quantum adversaries. The user interface is designed to be simple and user-friendly, allowing seamless sending and receiving of secure emails without requiring deep technical knowledge. The application enhances confidentiality, integrity, and authentication in email communication, making it suitable for defense, banking, healthcare, and government sectors where data security is critical. By integrating quantum-safe cryptographic techniques, the system provides a future-ready solution that safeguards communication against both classical and quantum computing threats.
Quantum computing significantly threatens traditional cryptographic methods used in securing web and mobile applications.Classical encryption algorithms, such as RSA and ECC, rely on mathematical problems that are infeasible for conventional computers to solve within a reasonable time frame.However, quantum algorithms like Shor's can efficiently break RSA and ECC [1], rendering them obsolete, while Grover's algorithm weakens symmetric encryption by reducing its brute-force security level.The potential impact of quantum computing extends to critical security areas, including secure web communications, mobile authentication, and blockchain-based applications [2], [3].This paper explores the vulnerabilities of current cryptographic standards under quantum computing, presents various attack scenarios affecting HTTPS, digital signatures, and cryptocurrency transactions, and discusses viable mitigation strategies.Key defensive approaches include post-quantum cryptography (PQC), quantum key distribution (QKD), hybrid cryptographic models, and increased key sizes for symmetric encryption.The urgency of transitioning to quantum-resistant security Breaking Traditional Encryption:
Several remote user authentication schemes have been proposed using external memory and smart cards. Smart card-based schemes have user mobility and deployment problems, and those based on external memory have a tamper resistance problem. Although Cherbal and Benchetioui’s scheme solved remote authentication problems using Elliptical Curve Cryptography and 2-Factor authentication, they still have not addressed key distribution, perfect forward secrecy, and session hijacking issues. This research proposes an enhanced multi-factor authentication and access control scheme based on the S13 quantum key distribution protocol, using a client file in an external memory. The proposed scheme combines the powers of an enhanced quantum key distribution, a lightweight tamper-resistance client file, and biometrics to overcome these limitations. The security of the proposed scheme was verified, validated, and evaluated against the reviewed scheme using various tools. The AVISPA simulation results showed that the proposed scheme is validated, secure against session hijacking, has a secure key distribution policy, and ensures perfect forward secrecy. The security functionalities analysis shows that the proposed scheme has the highest security index of 13 and is the only scheme that used the tamper-resistance client file in an external memory for the first time. The performance evaluation results showed that the proposed scheme is more efficient than the reviewed scheme with a computation cost of 0.83125s and 0.25902s and a percentage improvement of 48.48% and 73.98% for the respective user and server and a more efficient communication costs of 2112 bits than the reviewed scheme with a percentage improvement of 16.46%.
