Towards a Concrete Security Proof of Courtois, Finiasz and Sendrier Signature Scheme
Abstract. Courtois, Finiasz and Sendrier proposed in 2001 a practical code-based signature scheme. We give a rigorous security analysis of a modified version of this scheme in the...

General Group Oriented ID-based Cryptosystems with Chosen Plaintext Security
A scheme for general group oriented ID-based cryptosystems is proposed. This scheme allows an authorized subset in the general access structure to cooperatively decrypt the cipher...

Multisignatures secure under the discrete logarithm assumption and a generalized forking lemma
Multisignatures allow n signers to produce a short joint signature on a single message. Multisignatures were achieved in the plain model with a non-interactive protocol in groups ...
