Onion-Routed Multi-Circuit Key Establishment for Quantum-Resilient Sessions
Tushin Mallick, Ashish Kundu, Ramana Kompella
Public-key primitives that today anchor session-key establishment - RSA, Diffie-Hellman, and elliptic-curve cryptography - reduce to integer factorization or discrete logarithm and…
Aquaman: A Transparent Proxy Architecture for Quantum Resilient Key Establishment
Tushin Mallick, Ashish Kundu, Ramana Kompella
The harvest-now, decrypt-later (HNDL) threat--adversaries intercepting and archiving ciphertext today for retrospective decryption once quantum computers mature--turns the future q…
Quantum-Resistant Networks: A Review of Primitives, Protocols and Best Practices
Elisa Bertino, Ramana Kompella, Ashish Kundu +3
Large-scale quantum computers threaten the public-key cryptographic foundations underpinning today's network security infrastructures. While significant progress has been made in s…
The Quantum-Cryptographic Co-evolution
Ashish Kundu, Ramana Kompella
As quantum computing matures toward the realization of Cryptographically Relevant Quantum Computers (CRQC), global cryptographic infrastructure faces an existential threat. This pa…
Post-Quantum Cryptographic Analysis of Message Transformations Across the Network Stack
Ashish Kundu, Vishal Chakraborty, Ramana Kompella
When a user sends a message over a wireless network, the message does not travel as-is. It is encrypted, authenticated, encapsulated, and transformed as it descends the protocol st…
Uncertainty-Aware, Risk-Adaptive Access Control for Agentic Systems using an LLM-Judged TBAC Model
Charles Fleming, Ashish Kundu, Ramana Kompella
The proliferation of autonomous AI agents within enterprise environments introduces a critical security challenge: managing access control for emergent, novel tasks for which no pr…
Classifying Implementations of Cryptographic Primitives and Protocols that Use Post-Quantum Algorithms
Tushin Mallick, Cristina Nita-Rotaru, Ashish Kundu +1
Classification techniques can be used to analyze system behaviors, network protocols, and cryptographic primitives based on identifiable traits. While useful for defense, such clas…
