We present a brief survey of nonclassical linear theories continuum mechanics. Thus, we give concise characterization the Eringen–Edelen nonlocal theory elasticity, polar and micropolar media, Toupin couple-stress Eringen–Suhubi–Mindlin micromorphic theory, Mindlin gradient also local deformation elastic media that takes into account mass displacements.

This paper designed a new extended chaotic map-based Identity-based encryption (ECM-IBE) scheme and Identitybased digital signature (ECM-IDS) scheme using extended chaotic maps. The security of the ECM-IBE scheme is based on the hardness assumption of chaotic maps-based decisional DiffieHellman (CDDH) problem, whereas the ECM-IDS scheme is secure based on the difficulties of chaotic maps-based ...
