Towards an Auditable Cryptographic Access Control to High-value Sensitive Data [PDF]
International Journal of Electronics and Telecommunications, 2020 We discuss the challenge of achieving an auditable key management for cryptographic access control to high-value sensitive data. In such settings it is important to be able to audit the key management process - and in particular to be able to provide ...

How to Hide the Real Receiver Under the Cover Receiver: CP-ABE With Policy Deniability
IEEE Access, 2020 Attribute-based encryption (ABE) is a useful tool for sharing an encrypted data to a target group. In a ciphertext-policy ABE (CP-ABE) scheme, a ciphertext includes a policy to indicate its receivers and only those receivers can correctly decrypt the ...

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

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 ...

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 ...

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 ...
