Fuzzy Identity-Based Encryption [PDF]
, 2005 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 identity, ω ′, if and only if the identities ω and ω ′ are close to ...

Attribute‐based encryption implies identity‐based encryption [PDF]
IET Information Security, 2017 In this study, the author formally proves that designing attribute‐based encryption schemes cannot be easier than designing identity‐based encryption schemes. In more detail, they show how an attribute‐based encryption scheme which admits, at least, and policies can be combined with a ...

Identity-based encryption with efficient revocation [PDF]
Proceedings of the 15th ACM conference on Computer and communications security, 2008 Identity-based encryption (IBE) is an exciting alternative to public-key encryption, as IBE eliminates the need for a Public Key Infrastructure (PKI). The senders using an IBE do not need to look up the public keys and the corresponding certificates of the receivers, the identities (e.g.

TinyIBE: identity-based encryption for heterogeneous sensor networks [PDF]
, 2009 The area of security for heterogeneous sensor networks (HSNs) is still an open research field that requires new cryptographic solutions. Recent results have demonstrated that elliptic curve cryptography (ECC) and pairing-based cryptography (PBC) are ...

Modelling and simulation of a biometric identity-based cryptography [PDF]
, 2014 Government information is a vital asset that must be kept in a trusted environment and efficiently managed by authorised parties. Even though e-Government provides a number of advantages, it also introduces a range of new security risks.

Provably Secure Ciphertext-Policy Attribute-Based Encryption from Identity-Based Encryption [PDF]
Journal of Universal Computer Science, 2019 Ciphertext-policy attribute-based encryption (CP-ABE) is an access control mechanism where a data provider encrypts a secret message and then sends the ciphertext to the receivers according to the access policy which she/he decides.

Medical Image Encryption Using Modified Identity Based Encryption
Emitter: International Journal of Engineering Technology, 2019 The development of technology and communication also affects the level of security needed for digital image transmission. It is known that digital images now have important meanings in both communication and video conference.

Practical identity-based key agreement for secure communication in sensor networks [PDF]
, 2009 Despite much research effort key distribution in Wireless Sensor Networks (WSNs) still remains an open problem. In this paper we address this issue by proposing a simple identity- based key agreement scheme. Our protocol uses Identity-Based Cryptography (
