Identity-based Searchable Encryption Scheme Supporting Proxy Re-encryption [PDF]
Jisuanji gongcheng, 2019 The existing Identity-based Encryption with Keyword Search (IBEKS) cannot share search permissions.Therefore,an Identity-based Proxy Re-encryption with Keyword Search (IBPKS) scheme in cloud environment is proposed.The identity-based encryption algorithm

CCA-Secure Deterministic Identity-Based Encryption Scheme [PDF]
Journal of Universal Computer Science, 2019 Deterministic public-key encryption, encrypting a plaintext into a unique ciphertext without involving any randomness, was introduced by Bellare, Boldyreva, and O'Neill (CRYPTO 2007) as a realistic alternative to some inherent drawbacks in randomized ...

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 ...
