We introduce a new type of Identity-Based Encryption (IBE) scheme that we call Fuzzy Identity-Based Encryption. In Fuzzy IBE we view an identity as set of descriptive attributes. A Fuzzy IBE scheme allows for a private key for an identity,ω, to decrypt a ciphertext encrypted with an iden...
Fuzzy identity-based encryption (FIBE) scheme is a kind of identity-based encryption (IBE) scheme, in which any user's identity is composed by a set of attributes and any ciphertext encrypted under identity ID can be decrypted by using a private key corresponding to identity IDu2032 if IDu...

To eliminate public key certificates, identity based cryptosystems were proposed by Shamir [3]. Sahai and Waters [4] viewed the identity as a set of descriptive attributes. To tolerate small errors of the identity, they introduced the concept of fuzzy identity based encryption (FIBE) and construc...
In the existing system Identity Based Encryption, the public and private keys in the server can be compromised due to attacks in Public Key Generator. The context of publish/subscribe system means that only authenticated publisher are allowed to disseminate events in the cloud and only those ...

4) hierarchical identity based signature 分层的基于身份的签名 1. This paper presents ahierarchical identity based signaturescheme from a modification of Waters proposed identity based encryption scheme. 根据Waters提出的基于身份的加密方案,设计一个分层的基于身份的签名方案,并利用计算Diffie-Hellman问题的困难性...
A New Alignment Algorithm Of Fuzzy Fingerprint Vault Without Extra InformationBiometric based authentication can provide strong security guarantee about the identity of users. However, security of biometric data is particularly important as compromise of the data will be permanent. Cancelable biometrics ...
