5-pass zero-knowledge identity authentication scheme based on matrix completion problem by Houzhen WANG, Xinwei CAI, Yan GUO, Huanguo ZHANG

“…To solve the problem that most identity authentication schemes are vulnerable to quantum-computing attacks and low efficiency, a new 5-pass zero-knowledge identity authentication scheme was designed based on the matrix completion problem (MCP).Since the MCP is NP-complete, the proposed scheme has the potential to avoid quantum-computing attacks.Compared with the existing similar protocols, the proposed scheme reduced the fraud probability from 2/3 to 1/2 by adding a single round of interaction, and had the advantages of easy implementation and small key size.Moreover, based on the proposed zero-knowledge authentication scheme and Fiat-Shamir standard transformation method, a secure and efficient digital signature algorithm against quantum-computing can be obtained.…”

Detecting a New Type of Stokes V Profiles Observed by Hinode in a Sunspot by Hashem Hamedivafa

“…We analyze spectro-polarimetric observations of photospheric Fe~I lines with the Solar Optical Telescope aboard Hinode to find signatures of Doppler velocities on the Stokes V profiles. Stokes V profiles characterized by humps on both blue and red lobes with the same magnetic polarity as the sunspot umbrae were detected in both umbrae and penumbrae. …”
