In recent years, massively multiplayer online games (MMOGs) have become very popular by providing more entertainment and sociability than single-player games. In order to prevent c...
The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Although...
Non-interactive zero-knowledge proofs play an essential role in many cryptographic protocols. We suggest several NIZK proof systems based on prime order groups with a bilinear map...
- In recent years, many quantum cryptographic schemes have been proposed. However, it seems that there are many technical difficulties to realize them (except Quantum Key Distribut...

Verifiable Signature Sharing (VS ) enables the recipient of a digital signature, who is not necessarily the original signer, to share such signature among n proxies so that a subse...
