Hello everyone. Welcome to Con 42, mission Learning 2025. I am Vishnu Today. Today I'm discussing about quantum computing encryption trends in cybersecurity as quantum computing advances traditional encryption methods like RSA and ECC facing unpredicted challenges. This presentation. Explore how the cybersecurity landscape is evolving to address quantum thread, focusing on quantum safe encryption methods that will protect our digital future. We will examine vulnerabilities in current systems, explore forced quantum cryptography approaches. And discuss how organizations are preparing for all where quantum computers would break encryption. The quantum thread to traditional encryption. Yeah, traditional encryption. Mainly we are using. R, SA and ECC RSA and ECC. Vulnerabilities like the current encryption system depends on mathematical challenges that classical computers find unstoppable, but quantum computers can potentially solve this relatively easy mathematical foundation. Yep. Current traditional encryption, RSA. Depends on computational difficulty of factoring large prime products. While ECC protection lays on the complexity of solving discrete algorithms within elliptical curves source algorithm, this groundbreaking quantum algorithm it breaks both RSA and ECC encryption by solving their underlining mathematical problems. Exponentially faster than any classical approach. First, quantum cryptography. PQC, it's aims to develop encryption methods secure against both classical and quantum computer attacks. These approaches can implemented on current systems, allowing for smoother transactions as quantum computing advances. Yeah. One of the method is code based cryptography based on difficulties of decoding general linear codes. Yep. Now it it uses error correcting codes to create secure cryptographic systems. It's based on difficulties of decoding messages that have been purposefully corruption with errors. The security of the systems relates relates on the hardness of the certain coding theory problems like syndrome decoding and learning parity with noise. And next one, ASH based signatures. It's leverages quantum assist cryptographic ash functions. It is a type of digital signature scheme that utilizes as ash functions as core component offering forced quantum security. These signatures are promising alternative to traditional digital signatures, which are vulnerable to attacks from quantum computers. Hash based signatures are designed to be secure, even in presence of quantum computers by relaying on hardness of hash functions rather than mathematical problems like in factorization. Yeah. One more method is lattice based cryptography. It relates on hard lattice problems on quantum solving. Lattice. Basic cryptographic systems are a whole class of systems based on hard questions around spaces formed by commanding set of vectors for to form new vectors. All new vectors you can form by this combination are called lattice. A lattice is usually usually introduced as a 2D or 3D vectors. Because you can draw pictures that can make some institu sense. In practice, the number of variables of vectors can be arbitrary, and for a cryptography, they are much greater than three. Your quantum decision security is a desire to withstand both classical and quantum attacks. Yeah, first quantum cryptography advantages and challenges. Some advantages are it's a robust protection against future quantum quantum threats. Seamless integration with existing classical computing infrastructure was still cryptographic approaches tailored to specific security requirements. Yeah, it's a continuous innovation through extension, economic and industry research. Yeah. Now you forced to quantum cryptography will have some challenges significantly. It's increases processing power and memory requirements. Expanded key sizes leading to potential bandwidth and storage constraints. Necessity for rigorous ongoing crypto analysis to verify quantum resistance, complex standardization process and organizational adoption barriers co comparing traditional versus forced quantum approaches. Yeah in security aspect. Traditional cryptography mainly depends on mathematical problems like factoring and discrete aga algorithms. First, quantum cryptography. You say quantum resist problems. Lattice problem coding theory, quantum vulnerabilities. Highly vulnerable to so algorithm, solar algorithm can easily break traditional mathematical problems. First quantum cryptography, it's designed to resist quantum attacks, efficiency. Generally ENT on classical computers first content may require more computational resources. Key sizes in traditional, relatively small in first, quantum encryption is often large, larger impacting storage and transmission maturity. Yet traditional RSA and ECCR well-established extensively studied forced quantum cryptography near under undergoing active research and standardization. Quantum key distribution. How we distribute quantum keys from sender to receiver. Let's how analysis a sender is the receiver unless in course random binary data into quantum states transmit these photons to Bob, leveraging fundamental quantum mechanical properties. Measurement and safety. Safety. Bob measures incoming photons using randomly selected measurement basis. Both parties then compare their basis choice choices or classical channel returning only matching measurement to family shared key error de error detection and correction. The parties analyze error rates to detect potential error dropping, then employ classical error correction protocols and privacy amplification to distill final, secure, cryptographic key. Yeah, the system's key advantage is that any interruption attempt, attempted disturbs. The quantum states making is immediately detectable through increase error rate. Quantum key implementation and challenges current implementations or China 2000 kilometers based in Shanghai Quantum Link, satellite based quantum key distribution, demonstrate expanding range. Integration with adjusting fiber optic networks, technical limitations, distant limitations due to quantum state degradation. Slower key generation rate compared to classical methods. Specialized hardware requirement, increasing costs, practical challenges. Vulnerabilities to side channel attacks and classical components. Integration difficulties with existing network infrastructure. Scaling issues for widespread deployment, needs standardization efforts. Needs to launch first quantum cryptography standardization process on 2016. It is calling for algorithm proposal from the global cryptographic community from 2017 to 2022. N did rigorous evaluation and public cru scrutiny narrowed down to candidates based on security performance and implementation characteristics. First selection, NIST announced first set of selected algorithms on July, 2022. Crystals kyber for encryption crystals, d, lithium, falcon, and S effects for digital signatures. Yeah. Crystal Skyr for encryption. Crystal's de lithium s are lattice base with Shan performance and reasonable key sizes. Parcon offers compact lattice base signatures while Phoenix plus proves con conservate ash based approach with strong security assurance. Yeah. The strength of each key. Yeah. Adoption challenges in organization, if you want organization will face some challenges with the to adapt to, to adopt first quantum encryption. Crypto cryptography, legacy system. Compatibility. Yeah. In integrating quantum resist algorithms with existing infrastructure without operational distribution. Disturbs performance concerns, addressing increases competitional overhead and bandwidth requirement from larger key sizes. Transition. Period. Period risks managing hybrid implementation that maintain security during the migration from classical to first quantum protocols, global education and training, developing specialized cryptographic expertise to ensure correct implementation and management. Organizations face challenges in transmission forced quantum cryptography. This evaluation requests balancing immediate security requirement against future quantum threats while navigating complex technical limitations. Operational constraints, knowledge gaps. Success demands a coordinated global approach to ensure interpretability and comprehensive protection across digital ecosystems. Future proofing encryption systems. Hybrid approaches. Commanding, classical and forced quantum algorithms provides immediate enhanced security against both traditional and quantum threats, while enabling a smooth transition period. This complete systems offers fallback security. If vulnerabilities are discovered in the newer algorithms, security principles future proof systems must maintain or enhance. Fundamental security principles like confidentiality, integrity, and availability. Sta strategic implementation organization should adopt forward looking approach to address our rest New decrypt letter thread While carefully testing first quantum algorithms. Before full deployment to avoid introducing new vulnerabilities or performance issues. Yeah. Thank you all.
