Abstract

OT (oblivious transfer) is an important e-commerce technique to make information buyers be able to get desired information and preserve privacy at the sametime. Recently, Kim et al. proposed two 1-out-of-2 NIOT (non-interactive OT) schemes. They claimed the message sender can be verified in their schemes. Unfortunately, their schemes are insecure. In this paper, we will make thorough discussions on the design principles of secure verifiable NIOT schemes.
