This is a post about my story and experience with the placements conducted in IIT-Delhi during my undergraduate studies. Though it has been around 3 years since I sat for placements, I hope this post will still prove useful for some future generations of students, to give them a glimpse of the chaos on the interview day. But more importantly, having gone through the process and having seen how the results of that day affected the last 3 years of me and some of my batchmates, I wish to throw light on how insignificant the day is in the grand scheme of things.

We present CrypTFlow, a first of its kind system that converts TensorFlow inference code into Secure Multi-party Computation (MPC) protocols at the push of a button. The system enables secure inference on real-world networks like ResNet50 over the ImageNet dataset with running time of about 30 seconds for semi-honest security and under 2 minutes for malicious security.

In this work we introduce the notion of Functionally Encrypted Datastores, which allows multiple data owners to pool in data anonymously at two non-colluding servers and later allows malicious clients to perform search-and-compute queries on the collected data. Read more
We present CrypTFlow2, a cryptographic framework for secure inference over realistic Deep Neural Networks (DNNs) using secure 2-party computation. Read more
We present new and improved FSS gate constructions for applications motivated by ML. More specifically, we improve upon the best previous key sizes for Distributed Comparison Function and also provide new FSS gates for functions which are useful in mixed-mode/fixed-point computation. Read more
