This report summarizes our results from security analysis covering all 57 CAESAR first round candidates and over 210 implementations. We have manually identified security issues with three candidates, two of which are more serious, and these ciphers been withdrawn from the competition. We have developed a testing framework, BRUTUS, to facilitate automatic detection of simple security lapses and...

This paper presents NORX8 and NORX16, the 8-bit and 16-bit versions of the authenticated cipher NORX, one of the CAESAR candidates. These new versions are better suited for low-end systems—such as “internet of things” devices—than the original 32-bit and 64-bit versions: whereas 32-bit NORX requires 64 bytes of RAM or cache memory, NORX8 and NORX16 require just 16 and 32 bytes, respectively. Bo...

Deoxys-BC is the internal tweakable block cipher of authenticated encryption (AE) Deoxys family, in which Deoxys-II primary choice for use case ‘Defence depth’ among portfolio CAESAR competition. Improvements related-tweakey rectangle attacks on round-reduced using known distinguishers focussed this study. Under new related-key attack framework proposed by Dong et al. EUROCRYPT 2022, we present...

Underground oil pipelines are made of pressurized pipes, and when damage occurs, the consequences can be disastrous. Pipeline accidents caused by stress can be attributed to material corrosion, impractical design, manufacturing defect, environmental damage, and man-made destruction. In this study, by utilizing the stress analysis software CAESAR II, the stress of pipelines in high and steep slo...

In the last 15 years several electron-microscope studies of visceral and vascular smooth muscle of vertebrates have been published (see reviews by Dewey & Barr, 1968, and Burnstock, 1970). The presence of bottle-shaped invaginations of the sarcolemmal membrane (micropinocvtotic vesicles, caveolae intracellulares) (Caesar, Edwards & Ruska, 1957) is well known. However, it is generally accepted t...
