Post-Quantum Cryptography for Securing Banking API: A Survey

Kshitij Dhake, Atharva Dhake, Kartik Tichkule +2 more

Recent strides in quantum computing have posed a challenge to conventional classical cryptographic algorithms like RSA and Elliptic Curve Cryptography (ECC).With the progression of quantum computing, there is a possibility of vulnerability to traditional cryptography in the future, leading to significant concerns from the perspective of the security of the banking industry.In this survey, we will review the adoption of Post-Quantum Cryptography (PQC), focusing on specific schemes like CRYSTALS-Kyber or CRYSTALS-Dilithium, together with an approach involving hybrid cryptosystems, ensuring seamless implementation.In addition, several challenges related to computational costs, difficulties of integration, and the growing significance of flexible deployment of cryptography will be considered.In summary, the objective of the research is to help financial institutions and scholars determine efficient quantum-safe security systems that offer protection for banking APIs.

Mind the Gap: Policy vs Reality in Post-Quantum TLS Deployment

Nimesha Wickramasinghe, Frank Li, Sanjay Jha +1 more

Post-quantum cryptography (PQC) has evolved from a long-term planning concern into an operational priority. Following NIST's standardization of PQC algorithms, governments and standards bodies published transition roadmaps outlining migration timelines, priority sectors, and deployment strategies. However, our survey of these policies reveals substantial divergence in technical prescriptions and urgency. It remains unclear how widely PQC has been adopted in practice and how policy differences translate into observable deployment outcomes.
