During the last years, the industry sector showed particular interest in solutions which allow to encrypt and decrypt data within one clock cycle. Known as low-latency cryptography, such ciphers are desirable for pervasive applications with real-time security requirements. On the other hand, pervasive applications are very likely in control of the end user, and may operate in a hostile environm...

In this paper, we propose an accurate security evaluation methodology for block ciphers with a binary diffusion layers against division cryptanalysis. We illustrate the division property by the independence of variables, and exploit a one-toone mapping between division trails and invertible sub-matrices. We give a new way to model the propagation of division property of linear diffusion layers ...

The series of joint U.S.-Japan spaceborne scatterometers missions to provide continuous measurements of ocean wind vectors is reviewed. Examples of the scientific impact of the continuous effort in improving spatial resolution and coverage are provided,. The plan for future missions is reviewed.

Yasuhiro Katagiri NTT Basic Research Laboratories Midori-cho, Musashino, Tokyo, 180 Japan katagiri%[email protected] A theory of perspectivity is proposed to establish the foundation of the theory of situated agents. An account is then given, based on the theory of perspectivity, of the use of a seemingly perspectivity related expression, Japanese long-range reflexive “zibun. ” The theor...

In this study, a novel path clustering technique for adaptive path delay testing, where the test paths are altered according to the extracted device parameters, is proposed. The proposed algorithm is based on the k-means++ algorithm. By considering the probability function of the die-to-die systematic process variation, the proposed algorithm clusters path sets to minimize the total number of t...

Midori is a hardware-oriented lightweight block cipher designed by Banik et al. in ASIACRYPT 2015. It has two versions according to the state sizes, i.e. Midori64 and Midori128. In this paper, we explore the security of Midori64 against truncated differential and related-key differential attacks. By studying the compact representation of Midori64, we get the branching distribution properties of...
