最近由于偶然原因,接触了CP-ABE(Ciphertext-Policy Attribute-Based Encryption),学了一段时间,觉得挺精妙,记录并分享一下学习心得。 什么是ABE(Attribute-Based Encryption)? 一言以蔽之:这是一种可以实现精准化访问控制功能的基于公钥密码的算法。 ABE 根据访问策略嵌入实体的不同可以分为两种: CP-ABE:将访问策略...
上次提到了的一个由来,从那之后,业界大佬继续研究,得到了一种多权威机构的属性基加密。本文的主要内容基于顶会论文TCC 2007年的文章:Multi-authority Attribute Based Encryption Sahai和Waters描述过一个方案(称为SW),在这个方案中,发送方指定一个属性集和一个数字d对消息进行加密,这样当至少拥有d个给定属性的接收方...
A system for attribute-based encryption comprises a first encrypter ( 11 ) and a second encrypter ( 12 ). The first encrypter ( 11 ) comprises an input unit ( 1 ) for determining a message and a policy over a set of attributes, wherein the policy comprises a plurality of components,...

多权威属性基加密（Multi-authority Attribute Based Encryption）的提出，旨在解决单一权威机构方案中的挑战性问题，尤其是防止勾结的问题。该方案允许多个不同的权威机构同时操作，每个机构负责不同一组属性的密钥分发。然而，单一权威机构方案存在一个主要的限制：用户必须向受信任的一方证明其身份以获得解密...
接触CP-ABE（Ciphertext-Policy Attribute-Based Encryption），总结学习心得。ABE，即基于属性加密，是实现精准化访问控制的公钥密码算法。ABE分为两类：KP-ABE适用于灵活性需求高，用户数量少的场景；CP-ABE则适用于用户数量多，追求高扩展性的场景。CP-ABE在加密文件时，根据访问策略设置属性，符合属性的...
The concept of attribute-based encryption (ABE) was first introduced by Sahai and Waters in 2005 (Sahai and Waters,2005). ABE was later categorized into two types (Goyal et al.,2006): ciphertext-policy ABE (CP-ABE) and key-policy ABE (KP-ABE). In CP-ABE, each ciphertext is associat...
Attribute-based encryption (ABE) is a public-key-based one-to-many encryption that allows users to encrypt and decrypt data based on user attributes. A promising application of ABE is flexible access control of encrypted data stored in the cloud, using access polices and ascribed attributes assoc...
Being an effective cryptographic system attribute-based encryption (ABE) became hot topic of research among the researchers. ABE is a kind of public key cryptography system. It uses ciphertext and private key of user for the encryption purpose. This scheme hooked up ciphertext with attributes (e...
