Check-in Questions​
(1) Trusted Setup Security: Let’s suppose half of the parties colluded in the trusted setup process and told each other their secret contributions. Is the key generated by the trusted setup still secure? What is the minimum number of “honest parties” (parties that do not share their secret value with anyone else) needed to create a secure key?
Sample Answers
(1) Trusted Setup Security: Yes it’s still secure by DLP. You need at least one honest party to keep the key secure. This is because due to DLP, even if everyone else colludes, it is “hard” to find the one honest party’s secret contribution.
