Both the act of keeping information secret and the research on how to achieve it are included in the broad category of cryptography. When people refer to “information security,” they are referring to the study and use of methods that make data transfers harder to intercept. When we talk about “information security,”…

'Rupesh Kumar' 'Alessandro Zavatta'] Post-quantum public cryptosystems introduced so far do not define a scalable public key infrastructure for the quantum era. We demonstrate here a public certification system based on Lizama’s non-invertible key exchange protocol which can be used to implement a secure, scalable…

Owing to mathematical theory and computational power evolution, modern cryptosystems demand ingenious trapdoor functions as their foundation to extend the gap between an enthusiastic interceptor and sensitive information. This paper introduces an adaptive block encryption scheme. This system is based on product…

Cryptography, derived from the Greek for "hidden writing," uses mathematical techniques to secure information by making it unreadable. Though the scientific study of cryptography is relatively recent, starting about 100 years ago, its development accelerated with the rise of the information age in the early 1900s.…

Encrypting pictures quickly and securely is required to secure image transmission over the internet and local networks. This may be accomplished by employing a chaotic scheme with ideal properties such as unpredictability and non-periodicity. However, practically every modern-day system is a real-time system, for which…

'Jitendra Avasthi' 'Prerna Sharma'] Abstract - In polyalphabetic substitution the plain text's letters are enciphered differently according to their position. The name polyalphabetic suggests that there are more than one key so we have used two keys combination instead of just one, in order to produce the cipher text.…

Electronic health records (EHR) are often siloed across a network of hospitals, but researchers may wish to perform aggregate count queries on said records in entirety—e.g. How many patients have diabetes? Prior work has established a strong approach to answering these queries in the form of probabilistic sketching…
