Sketching the Error, Not the Product: Post Hoc Fault Recovery for Half Precision GPU Matrix Multiplication
Pranav Napolean, Vikas Srivastava, Napolean Periathambi
Silent data corruption (SDC) from defective accelerators now interrupts large scale training, yet deployed mitigations act on whole nodes. Algorithm based fault tolerance (ABFT) fo…
Syndrome Decoding for Silent Data Corruption in Quantized Integer GPU Arithmetic
Pranav Napolean, Vikas Srivastava, Napolean Periathambi
Quantized neural network inference runs integer matrix multiplications on GPU tensor cores, and the INT32 accumulators inside those cores have neither parity nor ECC. A transient f…
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…
