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 ...

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.

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.

Anonymous Homomorphic IBE with Application to Anonymous Aggregation
Cryptography, 2023 All anonymous identity-based encryption (IBE) schemes that are group homomorphic (to the best of our knowledge) require knowledge of the identity to compute the homomorphic operation.

Keyword Search Encryption Scheme for Designated Server in Email System [PDF]
Jisuanji gongcheng, 2020 The existing identity-based keyword search encryption schemes for designated server cannot satisfy the indistinguishability of keyword ciphertext.To meet the higher security requirements of email systems,this paper proposes an identity authentication ...

Idealizing Identity-Based Encryption [PDF]
, 2015 We formalize the standard application of identity-based encryption IBE, namely non-interactive secure communication, as realizing an ideal system which we call delivery controlled channel DCC. This system allows users to be registered by a central authority for an identity and to send messages securely to other users only known by their identity ...

Provably Secure Identity-based Conditional Proxy Re-encryption Scheme [PDF]
Jisuanji gongcheng, 2017 The conditional proxy re-encryption based on the traditional public key cryptosystem is mature,but the Identity-based Proxy Re-encryption(IBPRE) scheme,controlling agents’ permissions from the fine-grained level is a problem needed to be solved.Thus,this
