Abstract(in English) | Let Ω be a set of linear functions having a certain correlation. For two one-way functions,g,h,let Γ={h・w・g|w∈Ω}.For each γ∈Γ suppose there exists a device evaluating γ.On input x the device o utputs y=γ(x)but usually any user who uses the device cannot direc tly observe any intermediate computational value as well as the hidden linear function.However if the user can open the device then the linear function can be observed.The question to be examined in this research is that for some Ω given a randomly sele cted target device how many other devices should be opened to reveal the linear function contained in the target device? This question is related to techniques for constructing cryptographic key sharing devices. |
