The concept of witness indistinguishable and witness hiding was introduced by Feige and Shamir. A witness hiding proof system is an achievable substitute of zero knowledge proof systems in many cryptographic protocols, and is weaker requirements than zero knowledge. Kurosawa and Heng introduced the concept of witness indistinguishability and witness hiding to confirmation and disavowal protocols of undeniable signature schemes, their 3-move protocol is used to prove the validity/invalidity of DH-tuples and non DH-tuples. In this paper, we review the applications and of the 3-move protocol of Kurosawa and Heng, and discuss its use in various extensions of undeniable signature schemes.
