A Receiver Deniable Encryption Scheme
A practical efficient receiver deniable encryption scheme based on BCP commitment scheme and idea of Klonowski et al. is proposed in the paper. The analysis of the proposed schemes is also presented.
متن کاملAn Efficient Receiver Deniable Encryption Scheme and Its Applications
Deniable encryption is an important cryptographic primitive, essential in all cryptographic protocols where a coercive adversary comes to play with high potential. Deniable encryption plays a key role in the internet/electronic voting, electronic bidding, electronic auctions and secure multiparty computation. In this study a practical efficient receiver deniable encryption scheme based on BCP c...
متن کاملOn the Impossibility of Sender-Deniable Public Key Encryption
The primitive of deniable encryption was first introduced by Canetti et al. (CRYPTO, 1997). Deniable encryption is a regular public key encryption scheme with the added feature that after running the protocol honestly and transmitting a message m, both Sender and Receiver may produce random coins showing that the transmitted ciphertext was an encryption of any message m′ in the message space. D...
متن کاملProvably sender-deniable encryption scheme
The use of the well known provably secure public-key cryptoscheme by Rabin is extended for the case of the deniable encryption. In the proposed new sender-deniable encryption scheme the cryptogram is computed as coefficients of quadratic congruence, the roots of which are two simultaneously encrypted texts. One of the texts is a fake message and the other one is a ciphertext produced by public-...
متن کاملOn Minimal Assumptions for Sender-Deniable Public Key Encryption
The primitive of deniable encryption was introduced by Canetti et al. (CRYPTO, 1997). Deniable encryption is an encryption scheme with the added feature that after transmitting a message m, both sender and receiver may produce random coins showing that the transmitted ciphertext was an encryption of any message m′ in the message space. Deniable encryption is a key tool for constructing incoerci...
