DalamThe aims of this study, the researchers inspected that if X an algebraic variety over a field K and f is a f1+2ε(P) = P for other ε >- 1/2, then the aset of periods time is limited and the little one is 1+2ε. Also the researchers confirmed that if O be a separate estimate ring of characteristics zero with … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 4 Oct 2021 · 6,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe New Variable-Length Key Symmetric CryptosystemDavood Rezaei Pour, Mohamad Rushdan Md Said, Kamel Ariffin Mohd Atan, Mohamed OthmanProblem statement: In this study, we proposed a new 64-bit block cipher that accepted a variable-length key up to 512 bits, which was suitable for implementation in a variety of environments. Approach: The cipher algorithm was a 16-round Feistel network with a bijective function f and was made up of two key-dependent 16×16 S-boxes, bitwise rotations, and a carefully designed … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,213 accessesView PDFCite
