Oblivious Transfer Protocol with Verification
This addresses security issues in cryptographic protocols for unsupervised scenarios, but it appears incremental as it builds on existing DH key-exchange methods.
The paper tackles the problem of cheating in unsupervised random sequence generation by proposing an oblivious transfer protocol based on a variation of the DH key-exchange, with a verification method to ensure correctness without revealing the random numbers used by the parties.
Although random sequences can be used to generate probability events, they come with the risk of cheating in an unsupervised situation. In such cases, the oblivious transfer protocol may be used and this paper presents a variation to the DH key-exchange to serve as this protocol. A method to verify the correctness of the procedure, without revealing the random numbers used by the two parties, is also proposed.
