Lightweight cryptographic algorithms must develop to ensure the confidentiality and integrity of data in resource-constrained devices. Keys are vital every cryptography algorithm because they provide randomness, complexity, unexpected nature, robustness. A light encryption device (LED) is considered a lighter version advanced standard (AES), but it vulnerable related key attacks due using same ...

This paper discusses modern hash function construction using the NIST SHA-3 competition as a survey of modern hash function construction properties. Three primary hash function designs are identified based on the designs of SHA-3 candidates submitted as part of the NIST SHA-3 competition. These designs are Widepipe, Sponge, and HAsh Iterated FrAmework (HAIFA). Keywordscryptography; hashing; has...

This paper presents a theoretical and an empirical study of knowledge networks. This is an emerging phenomenon and a common form of work structure adopted also in the banking industry. Starting from the theoretical perspective, this work focuses on knowledge as an important factor in the modern economy of hyper-competition, needed not just to win, but also to play. In fact, the structure of eco...

Abs t rac t . RoboCup is an attempt to foster AI and intelligent robotics research by providing a standard problem where wide range of technologies can be integrated and exaznined. The first R o b o C u p competition was held at IJCAI-97, Nagoya. In order for a robot team to actually perform a soccer game, various technologies must be incorporated including: design principles of autonomous agen...

Two multivariate digital signature schemes, Rainbow and GeMSS, made it into the third round of NIST PQC competition. However, neither its way to being a standard due devastating attacks (in one case by Beullens, other Tao, Petzoldt, Ding). How should cryptography recover from this blow? We propose that, rather than trying fix HFEv- introducing countermeasures, better approach is return classica...

Green Cryptography is a technique which enables a natural succession of cryptographic primitives. Cryptographic operations are made energy-efficient in a way that it promises the use of approaches of lightweight cryptography. These Lightweight cryptographic algorithms are certainly worn for the devices which use low or extremely low resources. In this paper we have proposed a watermarking schem...

Abstract. In the digital age, cryptography is widely used in various important systems such as financial, military and government ones, medical records etc.
 The life of modern people closely connected with cryptography. We send messages via instant messengers without even considering which way security communications data ensured. buy things both online transfer money confidence transacti...
