Cryptanalysis of a Deniable Authentication Protocol based on Bilinear Pairing using Single Sender and Group Sender
The aim of an efficient deniable authentication protocol is to enable a receiver to identify the source of a given message but not to prove the identity of the sender. Lu and Cao [7,10] confirmed that the previous protocols had a common weakness in which any third party can impersonate the intended receiver to verify the signature of the given message, and they proposed a new protocol based on ...
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 کاملDeniable Authentication Protocol based on Bilinear Diffie - Hellman Algorithm
This paper describes a new deniable authentication protocol whose security is based Diffe-Hellman (CDH) Problem of type Decisional Diffie-Hellman(DDH) and the Hash DiffieHellman (HDDH) problem.This protocol can be implemented in low power and small processor mobile devices such as smart card, PDA etc which work in low power and small processor. A deniable authentication protocol enables a recei...
متن کاملSelf-stabilizing multiple-sender/single-receiver protocol
We present a new self-stabilizing protocol for many-to-one multicasting of messages. It is based on the window washing protocol of Costello and Varghese which uses positive acknowledgments for received messages. The assumed model uses a single queue at the receiver's side taking all the messages sent by N senders. The protocol provides ow control independently for every sender by dividing the q...
متن کاملAuthoCast - a mobility-compliant protocol framework for multicast sender authentication
Mobility is considered a key technology of the next generation Internet and has been standardized within the IETF. Rapidly emerging multimedia group applications such as IPTV, massive mutliplayer games (MMORPGs) and video conferencing increase the demand for mobile group communication, but a standard design of mobile multicast is still awaited. The open problem poses significant operational and...
