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…
Study of Post Quantum status of Widely Used Protocols
Tushin Mallick, Ashish Kundu, Ramana Kompella
The advent of quantum computing poses significant threats to classical public-key cryptographic primitives such as RSA and elliptic-curve cryptography. As many critical network and…
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…
A Generative Caching System for Large Language Models
Arun Iyengar, Ashish Kundu, Ramana Kompella +1
Caching has the potential to be of significant benefit for accessing large language models (LLMs) due to their high latencies which typically range from a small number of seconds t…
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…
