Low-energy finite field arithmetic primitives for implementing security in wireless sensor networks [PDF]
, 2006 In this paper we propose the use of identity based encryption (IBE) for ensuring a secure wireless sensor network. In this context we have implemented the arithmetic operations required for the most computationally expensive part of IBE, which is the ...

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

Tightly Secure Hierarchical Identity-Based Encryption [PDF]
Journal of Cryptology, 2019 AbstractWe construct the first tightly secure hierarchical identity-based encryption (HIBE) scheme based on standard assumptions, which solves an open problem from Blazy, Kiltz, and Pan (CRYPTO 2014). At the core of our constructions is a novel randomization technique that enables us to randomize user secret keys for identities with flexible length.The

Delegate and Verify the Update Keys of Revocable Identity-Based Encryption
IEEE Access, 2023 Revocable identity-based encryption (RIBE) is an extension of identity-based encryption (IBE) and it supports efficient revocation of private keys. In the past, many efficient RIBE schemes have been proposed, but research on efficiently delegating the ...
