TLDR
A new Transaction-based Access Control (TBAC) platform which integrates the standard attribute-based access control (ABAC) model and the blockchain system is presented, and a cryptosystem associated with TBAC (Crypto TBAC) is presented for ensuring secure attribute-exchanging and decision-making of dynamic policy.Abstract:
In this paper we focus on a new generation of secure resource sharing platform in a decentralized blockchain environment with flexible and diverse permission management, as well as verifiable and transparent access process. To do it, we present a new Transaction-based Access Control (TBAC) platform which integrates the standard attribute-based access control (ABAC) model and the blockchain system. In this platform, four types of transactions and Bitcoin-type cryptographic scripts are presented to describe the TBAC access control procedure corresponding to subject registration, object escrowing and publication, access request and grant. We also present a cryptosystem associated with TBAC (CryptoTBAC) for ensuring secure attribute-exchanging and decision-making of dynamic policy. We evaluate the security of CryptoTBAC from three aspects: transaction, authorization, and decision-making security.read more

Attribute-based encryption with non-monotonic access structures
TL;DR: In this paper, an attribute-based encryption (ABE) scheme was proposed that allows a user's private key to be expressed in terms of any access formula over attributes. But this scheme was limited to expressing only monotonic access structures.
