An argument system for NP is a proof system that allows efficient verification of NP
statements, given proofs produced by an untrusted yet computationally-bounded prover …

It has been recently discovered that some cyclic groups that could be used in Cryptography
admit a special bilinear pairing map that introduces extra structure to the group. Bilinear …

We propose a fully functional identity-based encryption scheme (IBE). The scheme has
chosen ciphertext security in the random oracle model assuming an elliptic curve variant of …

We introduce a short signature scheme based on the Computational Diffie-Hellman
assumption on certain elliptic and hyper-elliptic curves. The signature length is half the size …

In the recent past, great attention has been directed toward road surface condition
monitoring. As a matter of fact, this activity is of critical importance in transportation …

An aggregate signature scheme is a digital signature that supports aggregation: Given n
signatures on n distinct messages from n distinct users, it is possible to aggregate all these …

We propose a fully functional identity-based encryption (IBE) scheme. The scheme has
chosen ciphertext security in the random oracle model assuming a variant of the …

We construct a short group signature scheme. Signatures in our scheme are approximately
the size of a standard RSA signature with the same security. Security of our group signature …

Research related to the authentication schemes in vehicular ad hoc networks (VANETs) has
received significant attention recently. They substantially impact the security and privacy …

With the rapid developments occurring in cloud computing and services, there has been a
growing trend to use the cloud for large-scale data storage. This has raised the important …
