Microplastics removal strategies: A step toward finding the solution
《环境科学与工程前沿(英文)》 2022年 第16卷 第1期 页码 7-7 doi: 10.1007/s11783-021-1441-3
Microplastics are an emerging threat and a big challenge for the environment. The presence of microplastics (MPs) in water is life-threatening to diverse organisms of aquatic ecosystems. Hence, the scientific community is exploring deeper to find treatment and removal options of MPs. Various physical, chemical and biological methods are researched for MPs removal, among which few have shown good efficiency in the laboratory. These methods also have a few limitations in environmental conditions. Other than finding a suitable method, the creation of legal restrictions at a governmental level by imposing policies against MPs is still a daunting task in many countries. This review is an effort to place all effectual MP removal methods in one document to compare the mechanisms, efficiency, advantages, and disadvantages and find the best solution.

格上后向无关联性安全的验证者本地撤销群签名 Research Articles

群成员可撤销的群签名中,验证者本地撤销机制似乎是一种更为灵活的选择,因为在签名验证过程中,仅需验证者获取最新的撤销信息,而不涉及签名者。与经典的数论型构造相对应,Langlois等人给出了后量子安全的首个格上验证者本地撤销群签名。然而,截至目前,所有格上验证者本地撤销群签名方案暂不满足后向无关联性,该特性可保障群成员被撤销前其对消息签名的匿名性和无关联性。本文给出了首个格上后向无关联性安全的验证者本地撤销群签名方案,从而解决了这一公开问题。新方案为群公钥和群成员签名密钥节省了O(log N)的比特大小,并且没有任何公钥加密。特别地,新方案在随机谕言机模型下是可证明安全的,其困难性可归约至两个经典格上难题假设,即小整数解难题和差错学习难题。
