Attribute Based Group Signatures
نویسنده
چکیده
An Attribute Based Group Signature (ABGS) allows a verifier to request a signature from a member of a group who possesses certain attributes. Therefore, a signature should authenticate a person in a group and prove ownership of certain properties. The major difference between our scheme and previous group signatures, is that the verifier can determine the role of the actual signer within the group. In this paper we define the first ABGS scheme, and security notions such as anonymity and traceability. We then construct the scheme and prove it secure.

Fully Anonymous Attribute Tokens from Lattices
Anonymous authentication schemes such as group signatures and anonymous credentials are important privacy-protecting tools in electronic communications. The only currently known scheme based on assumptions that resist quantum attacks is the group signature scheme by Gordon et al. (ASIACRYPT 2010). We present a generalization of group signatures called anonymous attribute tokens where users are ...
متن کاملAttribute Based Signatures for Bounded Multi-level Threshold Circuits
Attribute based signature (ABS) permits users produce signatures using any predicate of attributes issued from an attribute authority. ABS disallows any group of colluding users to forge a signature based on a predicate of attributes which they do not individually satisfy. Earlier schemes in this direction are either in the generic group model or support only single-level threshold predicates. ...
متن کاملA Hybrid Multi-attribute Group Decision Making Method Based on Grey Linguistic 2-tuple
Because of the complexity of decision-making environment, the uncertainty of fuzziness and the uncertainty of grey maybe coexist in the problems of multi-attribute group decision making. In this paper, we study the problems of multi-attribute group decision making with hybrid grey attribute data (the precise values, interval numbers and linguistic fuzzy variables coexist, and each attribute val...
متن کاملA New Approach to Threshold Attribute Based Signatures
Inspired by developments in attribute based encryption and signatures, there has recently been a spurt of progress in the direction of threshold attribute based signatures (t-ABS). In this work we propose a novel approach to construct threshold attribute based signatures inspired by ring signatures. Threshold attribute based signatures, defined by a (t, n∗) threshold predicate, ensure that the ...
متن کاملTraceability, linkability and policy hiding in attribute-based signature schemes
Often we are less concerned with who signed something than with what attributes (director of this company etc.) they have. We propose three Attribute Based Signature schemes, namely, Decentralised Traceable Attribute Based Signatures DTABS, Attribute Based Signatures with UserControlled Linkability ABS-UCL, and Attribute Based Signatures with Hidden Expressive Policy ABS-HEP. The Traceability a...
