Web10 Chapter 2. Overview of Bit Commitment protocol 2.2 Security of classical Bit Commitment Several ideas are being used to construct bit commitment protocols without use of quantum resources. They are usually based on collision-free hashing functions [14] or pseudo-random generators [25]. The former assumes computationally bounded sender WebGeneral Properties of Quantum Bit Commitments (Extended Abstract) 629 a sender and a receiver, providing two security guarantees, hiding and bind-ing. Informally, the hiding property states that the committed bit is hidden from the receiver during the commit stage and afterwards until it is opened,
