The document proposes an algorithm for confidential multiparty computation with anonymous ID assignment using a central authority. It uses an anonymous ID assignment technique iteratively to assign nodes IDs from 1 to N with help from a central authority. This enhances secure sharing of complex data. The secure sum algorithm is used in each iteration of the anonymous ID assignment algorithm to anonymously share simple integer data. The algorithm assigns unique anonymous IDs to nodes so they can securely share data and keep private data private.
