Attribute-based signature (ABS) is a new cryptographic primitive, in which a signer can sign a message with his attributes, and the verifier can only known whether the signer owns attributes satisfying his policy. Moreover, the signature cannot be forged by any user not having attributes satisfy...
多权威的属性基加密(Multi-authority Attribute Based Encryption) 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...
This brings a huge workload to compute a signature and also a threat to security and privacy if the central authority is compromised. In this paper, we present an outsourced decentralized multi-authority attribute based signature (ODMA-ABS) scheme. Compared with existing multi-authority attribute ...
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消...

Attribute Based Encryption (ABE) scheme can achieve information sharing of one-to-many users, without considering the number of users and the users identity. But, the traditional single Attribute Authority (AA) ABE scheme can hardly meet requirements of different agencies in distributed application en...

Ciphertext-policy Attribute-based encryption (CP-ABE) is a promising tool for implementing finegrained cryptographic access control. While the uniqueness of generating private keys brings extra security issues. The key escrow is inherent in CP-ABE systems because the trusted authority has the power ...
