Comments on the SM2 Key Exchange Protocol

2011
SM2 key exchange protocol is one part of the public key cryptographic algorithm SM2 which has been standardized by Chinese state cryptography administration for commercial applications. It became publicly available in 2010 and since then it was neither attacked nor proved to be secure.

Ultra High-Speed SM2 ASIC Implementation

2014 IEEE 13th International Conference on Trust, Security and Privacy in Computing and Communications, 2014
In this paper, we present a high-performance elliptic curve cryptographic architecture over SCA-256 prime field by introducing a one-cycle full-precision multiplier. Based on the multiplier, we give a thorough bottom-up optimization in algorithm level.

Oxygen penetration into CaF2:Sm2+ crystals

Journal of Physics and Chemistry of Solids, 1968
Abstract The diffusion of O−− ions into CaF2:Sm2+ crystals has been directly observed by means of the decoloration of the crystals. In the presence of water vapor the O−− ions penetrate easily into the crystals, but in an O2 atmosphere penetration is quite limited.

Other Applications - The SM2

1993
The techniques described in this book are applicable in domains other than autonomous driving. In this chapter I present results which demonstrate this flexibility. I describe the application of these methods to the task of precisely guiding a robot called the Self Mobile Space Manipulator (SM2), which is designed to walk on the exterior of space ...

Magnetic characteristics of hexagonal Sm2−xRxCo16.4Zr0.6

Journal of Magnetism and Magnetic Materials, 1985
Abstract Magnetic properties (Curie temperatures, saturation magnetizations and anisotropy fields) of alloys of the composition Sm 2− x R x Co 16.4 Zr 0.6 with R = La , Ce and Y are presented. The ternary system Sm 2 Co 16.4 Zr 0.6 is hexagonal and hence contains Sm in the 2b and 2d positions.

Luminescence of Sm2+ -doped fluoride glasses

Journal of Luminescence, 1993
Abstract We have investigated the optical properties of Sm 2+ -doped fluoride glasses having three different compositions. The absorption and emission spectra reveal that the immediate fluorine environment surrounding the Sm 2+ ion is nearly identical for the three glass compositions, and is probably characterized by a high coordination number. The

Stability of Sm2+ in Sm1−RE3+S

Journal of Magnetism and Magnetic Materials, 1980
Abstract Critical concentrations and transition temperatures in Sm1−xRE3+xS have been investigated for several RE3+ -substituents. The valency υ of Sm in the metallic state is a more relevant parameter for the description of the phase transformation than the ionic size. It is related to the hybridization of local 4f-levels with 5d-conduction states.

One-photon reduction of Sm3+ to Sm2+

Journal of Photochemistry and Photobiology A: Chemistry, 1997
Abstract The photoreduction mechanism of Sm3+ to Sm2+ was studied using a KrF excimer laser. Reduction occurred via a one-photon process (different from previous suggestions). The reduction yield was 0.34 ± 0.09 in a methanol solution of 18-crown-6 with Sm3+. The oxidized solvent (*CH2OH radical) was observed in the transient spectrum.

Reversible photochromic processes in BaClF : Sm2+

Journal of Luminescence, 2001
Abstract The fluorescence intensity of Sm 2+ in BaClF has been found to decrease with the 325-nm light of a He–Cd laser and to recover with the 488-nm light of an Ar + ion laser at room temperature. At the same time, the increase or decrease in the optical absorption due to F centers has been observed. These results are interpreted in terms that Sm
