Machine-Checked Security Proofs of Cryptographic Signature Schemes
Abstract. Formal methods have been extensively applied to the certification of cryptographic protocols. However, most of these works make the perfect cryptography assumption, i.e....

Batch Verifications with ID-Based Signatures
An identity (ID)-based signature scheme allows any pair of users to verify each other's signatures without exchanging public key certificates. With the advent of Bilinear maps...

Bounded Vector Signatures and their Applications
Although malleability is undesirable in traditional digital signatures, schemes with limited malleability properties enable interesting functionalities that may be impossible to o...

Generic Security-Amplifying Methods of Ordinary Digital Signatures
We describe two new paradigms on how to obtain ordinary signatures that are secure against existential forgery under adaptively chosen message attacks (fully-secure, in short), fro...

ECDSA-Verifiable Signcryption Scheme with Signature Verification on the Signcrypted Message
Abstract. In this paper, we propose a signcryption scheme which provides all the following properties at the same time. (1) forward security: the private key of a sender does not h...
