In this paper,we re-examine the bit security of Paillier’s trapdoor *** show that given a random w=gcyN mod N2 ∈ZN2* the most significant bit of its class c is a hard-core predicate,under a standard assumption that is computing composite residuosity class is *** the simultaneous security,we prove that n number of the class c’s bits are simultaneously hard-core under the standard assumption,where n is the length of c.

如何在确保生态系统安全的同时有效地开发和利用资源、保障人类福祉是当前面临的挑战。近年来兴起的“安全公正空间”(Safe and Just Operating Space,SJOS)理论框架为人类可持续发展提供了有效的评估方法,即充分利用自然资源来提高人类社会福祉的同时确保环境生态安全。研究以长江中下游地区大通湖流域为例,根据流域内的社会经济数据、环境监测数据和湖泊沉积记录,从社会基础和环境系统两个方面构建该流域的SJOS框架,并利用环境库兹涅兹曲线来揭示总体环境变化特征。结果表明:流域内淡水利用、空气质量、水质均突破环境上限,处于危险的状态,此外流域内无贫困和产业创新两个社会基础维度的完成度相对较低。环境库兹涅兹曲线揭示了大通湖流域内社会-生态系统大致分为初始阶段(1950s—1980s)、严重退化阶段(1980s—2000s)和逐步改善(2000s后)三个阶段。研究为维持区域可持续发展提供了重要的参考信息,同时也为区域SJOS框架的构建提供了一种有效的方法。
