A symmetric LWE-based Multi-Recipient Cryptosystem
Saikat Gope, Srinivasan Krishnaswamy, Chayan Bhawal
This article describes a post-quantum multirecipient symmetric cryptosystem whose security is based on the hardness of the LWE problem. In this scheme a single sender encrypts mult…
Information Security and Privacy in the Digital World: Some Selected Topics
Jaydip Sen, Joceli Mayer, Subhasis Dasgupta +16
In the era of generative artificial intelligence and the Internet of Things, while there is explosive growth in the volume of data and the associated need for processing, analysis,…
A Scheme to resist Fast Correlation Attack for Word Oriented LFSR based Stream Cipher
Subrata Nandi, Srinivasan Krishnaswamy, Pinaki Mitra
In LFSR-based stream ciphers, the knowledge of the feedback equation of the LFSR plays a critical role in most attacks. In word-based stream ciphers such as those in the SNOW serie…
The application of -LFSR in Key-Dependent Feedback Configuration for Word-Oriented Stream Ciphers
Subrata Nandi, Srinivasan Krishnaswamy, Behrouz Zolfaghari +1
In this paper, we propose and evaluate a method for generating key-dependent feedback configurations (KDFC) for -LFSRs. -LFSRs with such configurations can be applied to any…
Fully Homomorphic Encryption based on Multivariate Polynomial Evaluation
Uddipana Dowerah, Srinivasan Krishnaswamy
We propose a multi-bit leveled fully homomorphic encryption scheme using multivariate polynomial evaluations. The security of the scheme depends on the hardness of the Learning wit…
A Somewhat Homomorphic Encryption Scheme based on Multivariate Polynomial Evaluation
Uddipana Dowerah, Srinivasan Krishnaswamy
We propose a symmetric key homomorphic encryption scheme based on the evaluation of multivariate polynomials over a finite field. The proposed scheme is somewhat homomorphic with r…
On Multisequences and their extensions
Srinivasan Krishnaswamy, Harish K. Pillai
In this paper we deal with the dimension of multisequences and related properties. For a given multisequence W and an m tuple of positive integers R, we define the R extension of W…
