A blind signature ensures that the server never learns which message it’s signing. A partially-blind signature protocol allows the server to see a part of the message, but hides another part. For example, a partially-blind signature protocol might allow the server to see the driver’s license data that it’s signing, but not learn the value K that’s being embedded within a specific part of the credential. A second way to accomplish this is for the User to simply commit to K (e.g., compute a hash of K), and store this value within the credential. The ZK statement would then be modified to prove: “I know some value K that opens the commitment stored in my credential.” This is pretty deep in the weeds.
揭示太阳活动区向量磁场结构和演化特征、发现太阳低层大气存在磁重联现象、发展太阳活动预报的观测研究基础……上世纪80年代起，汪景琇投身太阳物理学研究。尽管工作繁忙，汪景琇依然对科普工作投入了大量精力。1997年3月9日，上世纪发生在我国的最后一次日全食，与2400年回归一次的海尔—波普彗星相遇。应电视台之邀，汪景琇做了3个多小时电视直播，解释这一天文奇观。“直播后，走在路上总有人认出我，热情地问各种天文学问题。”汪景琇说，“这也更加坚定了我做科普的决心。”
