  • Patent number: 11018856
    Abstract: Parties communicate input values to a central entity by first decomposing them according to a chosen operation into share values, which are sent either directly or, in a transformed form such as being hashed and/or encrypted, via a bulletin board data structure, to respective nodes, such that no node receives the input value itself. The nodes then combine the share values using the operation and pass these respective node values to the central entity for computation of a global value. The operation of the parties and of the nodes may be made verifiable by aggregating the share values within a party or the received share values within a node using a data and computational structure such as a hash tree or skip list. Digital signing and timestamping may also be applied.
