For the problem that the security proof was difficult to be realized under the standard model in the existing ID-based ring signature schemes, an ID-based ring signature scheme proven secure in the standard model was proposed.Firstly, the formal definitions of security model and adversary model of ID-based ring signature were given.Then, a serra av

Understanding the processes that initiate volcanic eruptions after periods of quiescence are of paramount importance to interpreting volcano monitoring signals and mitigating volcanic hazards.However, studies of eruption initiation mechanisms are rarely systematically applied to high-risk volcanoes.Studies of erupted materials provide important ins
