Evaluating RSA Key Length: Impact on Security Hardness and Computational Efficiency
Abstract
The research investigate the impact of key length of RSA on security and computational efficiency, using simulation we evaluate how key length ranging from 1024 to 4096 bits perform for encryption/decryption process and their resistance to factorization attacks. The findings reveal that longer key length enhances the security by increasing the complexity of factorization. But they also incur higher computational cost, also they can affect the time and resource utilization. The result suggest that 2048-bit keys offer good security to general application whereas 3072-bit or 4096 bit keys are recommend for high security environment . We discuss these findings in the context of emerging quantum computing threats and propose guidelines in key length selection for future cryptographic system.
Customer Insight Towards UPI (Unified Payment Interface)
Abstract
This research paper aims to study the customer perception of the Unified Payment Interface (UPI) in India. The study analyzes the awareness level, satisfaction level, problems encountered, and duration to solve the problems of UPI users. The research concludes with aspects of awareness and adoption of UPI through comparison between gender, age, and occupational data of customers. The results of this study add to our knowledge about the acceptation of UPI and its usefulness in cashless and immediate transactions that influence young male customers who belong to service sectors.
HUMAN LIE DETECTOR/POLYGRAPHY FORENSIC TEST OF EVIDENCE
Abstract
The human lie detector polygraphy forensic exam, often known as a polygraph test, is a routinely used instrument in forensic investigations to assess persons' honesty by monitoring physiological reactions. This summary offers an overview of the polygraph test's major aspects, its applicability in forensic situations, and its limits. This article explains how forensic polygraph assesses the relevance and constitutionality of the evidence.
A polygraph is a device that detects changes in the body. Because most individuals, includes knowledgeable "lie catchers,' are unable to determine many techniques have been developed to help identify lies when someone is telling them. With the advent of science and technology, advanced means of lie detection have been created, removing the need for authorities to employ third-degree torture. The modern polygraph was invented in the early 1920s to record changes in a variety of physiological features, with equipment designed to record changes in breathing, cardiovascular activity, and sweat gland activity (forerunners to the present polygraph) arriving in the 1930s. Since then, the use of the polygraph as a 'lying detector' has been fraught with controversy, with supporters and detractors exchanging jabs based on incomplete facts and whole views. Polygraph exams are utilized in a variety of forensic settings, including criminal investigations, pre-employment screening, and security clearances. The polygraph's position in forensic investigations and its inherent controversies, implying a need for ongoing study and review to increase its reliability and acceptance within the legal system.
