Backward Compatible Identity-Based Encryption [PDF]
Sensors, 2023 In this paper, we present a new identity-based encryption (IBE) system that is named Backward Compatible Identity-based Encryption (BC-IBE). Our BC-IBE is proposed to solve the problem caused by the out-of-synchronization between users’ private keys and ...

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 ...

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 ...

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 ...

On the Anonymity of Identity-Based Encryption [PDF]
Journal of Applied Mathematics, 2013 Anonymity of identity-based encryption (IBE) means that given a ciphertext, one cannot distinguish the target identity from a random identity. In this paper, we thoroughly discuss the anonymity of IBE systems.

An efficient and provable secure revocable identity-based encryption scheme. [PDF]
PLoS ONE, 2014 Revocation functionality is necessary and crucial to identity-based cryptosystems. Revocable identity-based encryption (RIBE) has attracted a lot of attention in recent years, many RIBE schemes have been proposed in the literature but shown to be either ...

Efficient Leveled (Multi) Identity-Based Fully Homomorphic Encryption Schemes
IEEE Access, 2019 The first identity-based fully homomorphic encryption (IBFHE) scheme was constructed from identity-based encryption (IBE) and lattice-based cryptography by Gentry, Sahai, and Waters in CRYPTO 2013. Their IBFHE scheme is improved in this paper, exploiting

Identity-Based Proxy Re-encryption [PDF]
, 2007 In a proxy re-encryption scheme a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been proposed in the public-key setting. In this paper, we address the problem of Identity-Based proxy re-encryption, where ciphertexts are transformed from one identityto ...

Efficient Extended Chaotic Map-Based IBE for Industrial Environment
IEEE Access, 2022 Identity-based encryption is a public key-based method of encryption that enables communicating identities to use some individual and unique information, such as their physical IP addresses and MAC addresses, to identify them and as public keys.
