1. PI, Title: Design and Implementation of Secure Embedded System for Remote Monitored Implantable Medical Devices
   Funding agency: Ministry of Electronics and Information Technology (MeitY), Govt. of India
   Summary: Implantable Medical Device (IMD) is the device to give support to efficient medical treatments. With the remotely monitored IMDs being prevalent today, all of the patient’s data is readily available on these devices and is accessible over the internet. Also, the wireless connectivity can be exploited to compromise the security of IMDs and bring serious risk to the patient’s life when an adversary tampers with the data that is being transferred over the channel. This project aims to prevent the unauthorized access to IMDs that could endanger the patient’s life, and the final goal is to design and implement FPGA prototype (as well as ASIC chip) for memory and power aware secure IMDs

2. PI, Title: Cryptanalysis of Cryptographic Ciphers with emphasis on AES and RSA
   Funding agency: Ministry of Electronics and Information Technology (MeitY), Govt. of India
   Summary: Under this project practical attacks have been studied and implemented for AES-128 and RSA.
