The NIST LightWeight Cryptography (LWC) selection process aims to standardise cryptographic functionality which is suitable for resource-constrained devices. Since the outcome likely have significant, long-lived impact, careful evaluation of each submission with respect metrics explicitly outlined in call imperative. Beyond robustness submissions against cryptanalytic attack, related their impl...

Ciphers can be classified into two groups, based on the nature of the key. The family we’ll be talking about is symmetric-key the same key is used to encrypt and decrypt the data. There is a second family, called asymmetric-key cryptography. In assymetric key cryptography, the sender uses one key to encrypt and second to decrypt. Discussion and analysis of assymetric-key cryptography is beyond ...

Because wireless sensor networks usually operate on unattended mode in hostile environments, the sensitive data should be protected using some sort of cryptography. Symmetric key scheme is more appropriate cryptography for wireless sensor networks due to its low energy consumption and simple hardware requirements, but most of them cannot provide sufficient security level (e.g. integrity, confid...

The book is aimed at bridging the gap between cryptography and its standard applications. From my point of view, it has achieved its goal. This book presents basic tools of cryptography with applications in communication and information security. This book is a compilation of author’s lecture notes that he used for teaching cryptography to undergraduate students. Though this book is titled like...

This paper presents an encryption scheme suitable for direct diffusion protocols. We have calculated computational and communication overheads in terms of energy consumption using Directed Diffusion protocol. Public-key cryptography has been observed to suffer from high computational complexity and overhead. The symmetric-key schemes can be utilized more efficiently in order to provide more sec...

The data transfer, either through wired media or wireless media, needs privacy or a security. In case of wireless means of communication when the data is in the route, in order to protect the data from going into the hands of an unauthorized person, the two main techniques are used i.e. Steganography and Cryptography. Steganography hides the messages inside other harmless digital media without ...

Though Multivariate Polynomial Cryptography (MPC) is a potential candidate for Post Quantum Cryptography (PQC), schemes based on it are mostly well developed for digital signatures only. In this paper we explore the possibility of using multivariate polynomial systems for symmetric encryption and secret sharing.
