Identity authentication scheme based on identity-based encryption
网络与信息安全学报, 2016 In large-scale communication nodes network,there are a large number of network nodes and so many types of equipment.So there are problems of certificate management difficulties and resource waste in the tradi-tional PKI cryptosystem.A mutual node ...

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 ...

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.

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 ...

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.

Dynamic Searchable Encryption Scheme Based on Identity [PDF]
Jisuanji gongcheng, 2019 Searchable encryption technology saves user’s local storage resources and simplifies user’s search operation.However,most searchable encryption schemes are only static search.Therefore,this paper presents a dynamic searchable encryption scheme based on ...
