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.

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 (

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 ...

Identity-Based Matchmaking Encryption without Random Oracles [PDF]
, 2021 Identity-based matchmaking encryption (IB-ME) is a generalization of identity-based encryption where the sender and the receiver can both specify a target identity: if both the chosen target identities match the one of the other party, the plaintext is ...

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

Multi-Keyword Searchable Identity-Based Proxy Re-Encryption from Lattices
Mathematics, 2023 To protect the privacy of cloud data, encryption before uploading provides a solution. However, searching for target data in ciphertext takes effort. Therefore, searchable encryption has become an important research topic.
