Observation and abstract behaviour in specification and implementation of state-based systems [PDF]
, 2001 Classical algebraic specification is an accepted framework for specification. A criticism which applies is the fact that it is functional, not based on a notion of state as most software development and implementation languages are.

Hierarchical Attribute-Based Signatures
, 2018 Attribute-based Signatures (ABS) are a powerful tool allowing users with attributes issued by authorities to sign messages while also proving that their attributes satisfy some policy. ABS schemes provide a flexible and privacy-preserving approach to authentication since the signer’s identity and attributes remain hidden within the anonymity set of ...

Decentralized Traceable Attribute-Based Signatures [PDF]
, 2014 We provide a formal security model for traceable attribute-based signatures. Our focus is on the more practical case where attribute management is distributed among different authorities rather than relying on a single central authority. By specializing our model to the single attribute authority setting, we overcome some of the shortcomings of the ...

One Attribute-Based Proxy Signature [PDF]
Proceedings of the 2015 International Conference on Mechatronics, Electronic, Industrial and Control Engineering, 2015 For Identity-based proxy signature, when the original signer cannot sign for some reason,he delegate his signing capabilities to a person with an identity, in order to expand the scope of the proxy signer, an entity with a series of attribute properties can perform the right of signature.

Towards Practical Attribute-Based Signatures
, 2015 An attribute-based signature ABS is a special digital signature created using a dynamic set of issued attributes. For instance, a doctor can sign a medical statement with his name, medical license number and medical speciality. These attributes can be verified along with the signature by any verifier with the correct public keys of the respective ...
