Breaking the Bounded Entanglement Barrier for Quantum Position Verification
Amit Behera, Vipul Goyal
Position verification, introduced by Chandran et al. (SIAM J. Computing 2014), allows verifiers to test a prover's claimed position by an interactive protocol. Classical position v…
Decisional Monogamy-of-Entanglement for Coset States and Applications to Unclonable Cryptography with Correlated Challenges
Amit Behera, Alper Cakan, Alper Çakan +1
A main application of quantum information in cryptography is copy-protection, where we encode a functionality (such as a decryption key or software) into a reusable quantum state s…
A New World in the Depths of Microcrypt: Separating OWSGs and Quantum Money from QEFID
Amit Behera, Giulio Malavolta, Tomoyuki Morimae +2
While in classical cryptography, one-way functions (OWFs) are widely regarded as the "minimal assumption," the situation in quantum cryptography is less clear. Recent works have pu…
A Modular Approach to Unclonable Cryptography
Prabhanjan Ananth, Amit Behera
We explore a new pathway to designing unclonable cryptographic primitives. We propose a new notion called unclonable puncturable obfuscation (UPO) and study its implications for un…
