, 1991 A shared secret scheme is normally specified in terms of a desired security, Pd, and a concurrence scheme, Γ. The concurrence scheme (aka access structure) identifies subsets of participants (also called trustees or shareholders) each of which should be able to cooperatively recover the secret and/or initiate the controlled action.

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin
Deep Underground Science and Engineering, EarlyView.The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Deep Underground Science and Engineering, EarlyView.This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

LWE‐based verifiable essential secret image sharing scheme ((t,s,k,n)$( {t,s,k,n} )$ ‐ VESIS)
IET Image ProcessingIn traditional secret image sharing schemes, shareholders have similar situations, and to recover the secret image, they must be present as many as the threshold.

European Journal of Social Psychology, EarlyView.ABSTRACT This research examines how wrongdoers may use narration to ‘work through’ a transgression committed, towards self‐forgiveness and reconciliation. In Study 1 (N = 30), reflexive thematic analysis was used to identify narrative types observable in wrongdoers’ storying of a recent interpersonal transgression, informing our conceptual framework ...
