Zero-knowledge set is a primitive introduced by Micali, Rabin, and Kilian (FOCS 2003) which enables a prover to commit a set to a verifier, without revealing even the size of the set. Later the prover can give zero-knowledge proofs to convince the verifier of membership/nonmembership of elements in/not in the committed set. We present a new primitive called Statistically Hiding Sets (SHS), similar to zero-knowledge sets, but providing an information theoretic hiding guarantee. This is comparable to relaxing zero-knowledge proofs to witness independent proofs. More precisely, we continue to use the simulation paradigm for our definition, but do not require the simulator (nor the distinguisher) to be efficient. We present a new scheme for statistically hiding sets, which does not fit into the “Merkletree/mercurial-commitment” paradigm used for all zero-knowledge set constructions so far. This not only provides some efficiency gains compared to the best possible schemes in that paradigm, but also lets us provide statistical hiding, without the prover having to maintain growing amounts of state with each new proof; this is not known to be possible with the previous approach.

The Soviet Union entered the 1960s with confidence after its victory in World War II, coupled with promising economic and political prospects. The Soviet bloc was having unprecedented productivity driven by the Information Technology Revolution, along with advances in finance, transportation, and agriculture. The Soviet bloc economy also received a boost following Joseph Stalin's death in 1953 and Nikita Khrushchev's reforms. The Soviets, with East Germany's Walter Ulbricht in the vanguard, were intent on harnessing the IT Revolution and cybernetics to overtake the West. Ulbricht's reform program of the 1960s, the New Economic System, was founded on cybernetics, cybermarxism, and innovation. Erich Apel, head of the State Planning Commission, designed the cybernetics program anchored on three basic reforms: decentralization, price and interest rate reform, and improved accounting and control systems. A focus of decentralization was forest management.
