A Non-Interactive Deniable Authentication Scheme in the Standard Model
Deniable authentication protocols enable a sender to authenticate a message to a receiver such that the receiver is unable to prove the identity of the sender to a third party. In contrast to interactive schemes, non-interactive deniable authentication schemes improve communication efficiency. Currently, several non-interactive deniable authentication schemes have been proposed with provable security in the random oracle model. In this paper, the authors study the problem of constructing non-interactive deniable authentication scheme secure in the standard model without bilinear groups.
