Hi every one,

we have 4 persons A, B, C and D witch want to know the averge of their salary SA SB SC SD but no one wants that the others know his salary. For that they use this protocol: 1.A->B: [N+SA ]KB 2.B->C:[N+SA+SB]KC 3.C->D:[N+SA+SB+SC]KD 4.D->A:[N+SA+SB+SC+SD]KA where the notation [m]KY represents the message x crypted xith the public key of y

Is this protocol certain. can we trust it. want you please give me justification. thanks for help.
