Attribute-Based Encryption (ABE) approaches provide the building blocks to establish an ABAC framework. Due to the access policies incorporated into the data, ABE-based ABAC approach can isolate the access cont
Access Control Mechanism (ACM) development has been approached many times; thus, there are many theoretical concepts for solving this problem. While early access control mechanisms, such as limiting the memory addresses available to a user/process, could not restrict access on a per-operation basis...
Attribute-based encryption (ABE) is a new public key encryption based on users attributes. In this paper, we present a new method to realize a secure fine-grained access control to PHRs, which is based on emerging ABE primitives. In more details, PHR owners divide the PHR data in terms ...
76% of organizations detected insider threat activity over the past five years, butonly 30%believed they had the right tools to handle them. The situation is dire, but there’s a dependable solution. It’s called attribute-based access control (ABAC). ...
As cloud computing becomes prevalent, more and more sensitive data is being centralized into the cloud for sharing, which brings forth new challenges for outsourced data security and privacy. Attribute-based encryption (ABE) is a promising cryptographic

基于区块链的物联网系统(IoT)中的细粒度访问控制。传统的集中式访问控制中,密钥会随着用户的增加呈线性直线增长。本文提出了基于属性加密机制可以实现有效的细粒度访问控制。 Method 1. Technique 1.1 Attribute-Based Encryption 基于属性加密机制 ABE机制是指将数据和数据用户属性相关联的一组规则,以提供对数据的访问...
1 Introduction As a relatively new encryption technology, attribute-based encryption(ABE) has attracted lots of attention because ABE enables efficient one-to-many broad- cast encryption and fine-grained access control system. Access control is one of the most common and versatile mechanisms used ...
A secure Time-domain Attribute-based Access Control (TAAC) scheme, to secure the cloud-based video content sharing. This project additionally uses a secure time-domain attribute-based encryption scheme by embedding the time into both the cipher-texts and the keys, so the user holding specific ...
