Abstract: There is provided a method and system for selection of response message(s), comprising: receiving from an initiator client terminal a function message including an unencrypted target value and a public key, receiving respective response messages to the function message from responding client terminals, each respective response comprising an unencrypted partial value of the target value and a parameter encrypted with the pubic key, receiving, from the initiator client terminal, a selection of response message(s) according to a ranking of the encrypted parameters, wherein a sum of the unencrypted partial values of the selected response message(s) is according to a requirement of the target value, and receiving a validation for the selected response message(s) from corresponding responding client terminals, wherein each of the corresponding responding client terminals is provided with all partial values and all unencrypted parameters associated with all of the selected response message(s).
