COZMO-A New Lightweight Stream Cipher
Krishnendu Rarhi, Rhea Bonnerji, Simanta Sarkar +1
This paper deals with the merger of the two lightweight stream ciphers: A5by1 and Trivium. The idea is to make the key stream generation more secure and to remove the attacks of th…
Systematization of a 256-bit lightweight block cipher Marvin
Sukanya Saha, Krishnendu Rarhi, Abhishek Bhattacharya
In a world heavily loaded by information, there is a great need for keeping specific information secure from adversaries. The rapid growth in the research field of lightweight cryp…
Cryptanalysis of a Chaotic Key based Image Encryption Scheme
Pratyusa Mukherjee, Krishnendu Rarhi, Abhishek Bhattacharya
Security of multimedia data is a major concern due to its widespread transmission over various communication channels. Hence design and study of good image encryption schemes has b…
Synthetic data generation for Indic handwritten text recognition
Partha Pratim Roy, Akash Mohta, Bidyut B. Chaudhuri
This paper presents a novel approach to generate synthetic dataset for handwritten word recognition systems. It is difficult to recognize handwritten scripts for which sufficient t…
Exact Semidefinite Formulations for a Class of (Random and Non-Random) Nonconvex Quadratic Programs
Samuel Burer, Yinyu Ye
We study a class of quadratically constrained quadratic programs (QCQPs), called {\em diagonal QCQPs\/}, which contain no off-diagonal terms for , and we provide…
Cross-language Framework for Word Recognition and Spotting of Indic Scripts
Ayan Kumar Bhunia, Partha Pratim Roy, Akash Mohta +1
Handwritten word recognition and spotting of low-resource scripts are difficult as sufficient training data is not available and it is often expensive for collecting data of such s…
Script Identification in Natural Scene Image and Video Frame using Attention based Convolutional-LSTM Network
Ankan Kumar Bhunia, Aishik Konwer, Ayan Kumar Bhunia +3
Script identification plays a significant role in analysing documents and videos. In this paper, we focus on the problem of script identification in scene text images and video scr…
