IND-CCA2: INDistinguishability under adaptive Chosen Ciphertext Attack 总的来说:除了IND-CCA1的能力以外,对手在收到C CC后可以访问oracle,但是不可以发送C CC给解密oracle。 在IND-CCA1的基础上,去掉了只能在短时间内得到解密帮助这个不现实的条件,即在这个更强安全性的攻击模型中,对敌手A的解密帮助在午餐攻...

We need to construct an fully homomorphic encryption scheme which satisfies strong security for practical use to use a homomorphic encryption scheme practically, but essentially, we cannot construct a scheme which satisfies IND-CCA2 security Thus, one of the strongest security notions for homomorphic ...
近日,纽欧申医药(以下简称“公司”)管线产品NS-041的首个新药临床试验申请(IND)获得国家药品监督管理局药品审评中心(NMPA-CDE)正式受理。NS-041是一款拥有全球自主知识产权的高选择性KCNQ2/3激活剂,公司计划开发治疗癫痫和重度抑郁症等适应症。 元生创投于2023年1月参与纽欧申医药Pre-A轮融资。 NS-041高选择性地...
2021年Q1全国首次申请受理IND的1类小分子化药达到60个品种(回顾阅读:《近60个1类化药首次IND!石药、贝达、正大天晴、恩华...》);而刚刚过去的Q2,这个数字为63,追平了第1季度;进一步回顾2020全年,全国首次申请受理IND的小分子化药品种...

Our transformation first turns an FHE scheme into a C C A 2 extrm{CCA2} -secure scheme where a part of the ciphertext retains the homomorphic properties and then extends it with a succinct non-interactive argument of knowledge (SNARK) to verifiably control the evaluation algorithm. In fact,...
