Abstract

In multiple grade proxy signatures, the signing right can be delegated from one grade to the next grade. In this paper, we first introduce a code-based multiple grade proxy signatures based on Stern's identification scheme. The proposed scheme is the first code-based multiple grade proxy signature. Our scheme is secure on the syndrome decoding problem and satisfies verifiability, unforgeability, undeniability, non-transferability and distinguishability properties, which are the security requirements for a multiple grade proxy signature.
