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...

Stand-Alone and Setup-Free Verifiably Committed Signatures
Abstract. In this paper, we first demonstrate a gap between the security of verifiably committed signatures in the two-party setting and the security of verifiably committed signat...

Adaptive Security in the Threshold Setting: From Cryptosystems to Signature Schemes
Threshold cryptosystems and signature schemes give ways to distribute trust throughout a group and increase the availability of cryptographic systems. A standard approach in design...

Strengthened Security for Blind Signatures
Abstract. Provable security is a very nice property for cryptographic protocols. Unfortunately, in many cases, this is at the cost of a considerable loss in terms of efficiency. Mo...

Provably secure ciphertext policy ABE
In ciphertext policy attribute-based encryption (CP-ABE), every secret key is associated with a set of attributes, and every ciphertext is associated with an access structure on a...
