Pivot: Proactive and Verifiable Threshold Oblivious Pseudorandom Functions From Isogeny Group Actions
Abhinav Sharma, Vikas Srivastava
Oblivious pseudorandom functions (OPRFs) allow a client to evaluate a keyed pseudorandom function on a private input without revealing that input to the server. In a threshold OPRF…
A Post-Quantum Secure Lattice-Based Forward-Secure Identity Based Encryption with Applications to Internet of Things Architecture
Abhishek Kumar, Vikas Srivastava, Sumit Kumar Debnath +1
The rapid expansion of the Internet of Things (IoT) has led to an unprecedented scale of data exchange across heterogeneous and resource-constrained devices. Ensuring confidentiali…
Hierarchical Identity-Based Signature with Designated Aggregator from Lattices
Stuti Kumari, Kunal Dey, Vikas Srivastava +1
In hierarchical organizations, authenticating data from multiple users can be complex and resource-intensive. Hierarchical Identity-Based Signature with Designated Aggregator (HIBS…
A Post-Quantum Secure End-to-End Verifiable E-Voting Protocol Based on Multivariate Polynomials
Vikas Srivastava, Debasish Roy, Sihem Mesnager +3
Voting is a primary democratic activity through which voters select representatives or approve policies. Conventional paper ballot elections have several drawbacks that might compr…
Error Detection Schemes for Barrett Reduction of CT-BU on FPGA in Post Quantum Cryptography
Paresh Baidya, Rourab Paul, Vikas Srivastava +1
A fault can occur naturally or intentionally. However, intentionally injecting faults into hardware accelerators of Post-Quantum Cryptographic (PQC) algorithms may leak sensitive i…
Energy-Efficient NTT Sampler for Kyber Benchmarked on FPGA
Paresh Baidya, Rourab Paul, Vikas Srivastava +1
Kyber is a lattice-based key encapsulation mechanism selected for standardization by the NIST Post-Quantum Cryptography (PQC) project. A critical component of Kyber's key generatio…
