Deniable Encryptions Secure against Adaptive Chosen Ciphertext Attack
The deniable encryption is a type of encryption which can hide the true message while revealing a fake one. Even if the sender or the receiver is coerced to show the plaintext and the used random numbers in en...

Improved Implementations of Cryptosystems Based on Tate Pairing
Hu et al. first studied pairing computations on supersingular elliptic curve with odd embedding degree k = 3 and applied them to Identity-based cryptosystems. In this paper, a careful analysis of the pairing comp...

Divisible On-Line/Off-Line Signatures
On-line/Off-line signatures are used in a particular scenario where the signer must respond quickly once the message to be signed is presented. The idea is to split the signing procedure into two phases: the o...

How to Authenticate Real Time Streams Using Improved Online/Offline Signatures
Providing authentication protocols for real time streams is a challenging task. This is because the authentication rate is very important for real time streams, whereas it is usually a bottleneck. Using improv...

A Ring Signature Scheme Based on the Nyberg-Rueppel Signature Scheme
Ring signature allows to specify a set of possible signers without revealing which member actually produced the signature. This concept was first formalized in 2001 by Rivest, Shamir, and Tauman[3]. Authors of...
