👉 Secure Multiparty Computation (SicCom) is a cryptographic technique that allows multiple parties to jointly compute a function over their private inputs without revealing those inputs to each other. Essentially, it enables collaboration on computations while maintaining privacy. Each party holds a piece of data that is sensitive, and through complex protocols involving encryption and secret sharing, they can compute the desired output without learning anything about the other parties' inputs. This is achieved by dividing the data into shares, which are distributed among participants, and using these shares to perform computations in a way that ensures no single party can reconstruct the original data. The security of SicCom relies on mathematical constructs like homomorphic encryption, garbled circuits, and secret sharing schemes, ensuring that the computation is both correct and private.
