The shifted-prime Erdős-Wintner law for primitive-root determinant densities: extremal order, dimension zero, and Fourier decay
Vipin Singh Sehrawat
For a prime , let , the limiting density of matrices over with primitive-root determinant. Its limiting law over th…
UC-Secure Star DKG for Non-Exportable Key Shares with VSS-Free Enforcement
Vipin Singh Sehrawat
Distributed Key Generation (DKG) lets parties derive a common public key while keeping the signing key secret-shared. UC-secure DKG requires a verifiable-sharing enforcement layer…
Function-private Conditional Disclosure of Secrets and Multi-evaluation Threshold Distributed Point Functions
Nolan Miranda, Foo Yee Yeo, Vipin Singh Sehrawat
Conditional disclosure of secrets (CDS) allows multiple parties to reveal a secret to a third party if and only if some pre-decided condition is satisfied. In this work, we bolster…
Extremal Set Theory and LWE Based Access Structure Hiding Verifiable Secret Sharing with Malicious-Majority and Free Verification
Vipin Singh Sehrawat, Foo Yee Yeo, Yvo Desmedt
Secret sharing allows distributing a secret among several parties such that only authorized subsets, specified by an access structure, can reconstruct the secret. Sehrawat and Desm…
Certificate and Signature Free Anonymity for V2V Communications

Anonymity is a desirable feature for vehicle-to-vehicle (V2V) communications, but it conflicts with other requirements such as non-repudiation and revocation. Existing, pseudonym-b…
Bi-Homomorphic Lattice-Based PRFs and Unidirectional Updatable Encryption
Vipin Singh Sehrawat, Yvo Desmedt
We define a pseudorandom function (PRF) to be bi-homomorphic when it is fully Key homomorphic and partially Input Homomo…
