Universal thresholdizer (UT) was proposed by Boneh et al. in CRYPTO'18 as a general framework for thresholdizing non-threshold cryptographic primitives where a set of $N$ servers, each gets a share such that any set of $k$ servers, each produces a partial result, which can be combined to generate the final result. In many applications of threshold cryptography such as the protection of private keys in …
