WebFeb 25, 2013 · At Crypto’07, Goyal introduced the notion of accountable authority identity-based encryption (A-IBE) in order to mitigate the inherent key escrow problem in identity-based encryption, and... WebAbstract: Identity-based encryption (IBE) is a powerful mechanism for maintaining security. However, systems based on IBE are unpopular when compared with those of the public-key encryption (PKE). In our opinion, one of the reasons is a gap between theory and practice.

WebThe core of our scheme is a novel extension of the double-strand paradigm, which was originally proposed by Golle {\it et al.} (CT-RSA'04) and later extended by Prabhakaran and Rosulek (Crypto'07), to the well-known Gentry-IBE (Eurocrypt'06). http://www.ijnc.org/index.php/ijnc/article/download/228/229 how long can goldfish remember things

"WebUnfortunately, this paradigm cannot be applied to the well-known Gentry-IBE [12] directly, as it is of IND-ID-CCA security which contradicts to the homomorphic property.

Identity-Based Encryption for Fair Anonymity Applications: …

WebAbstract: Identity-based encryption (IBE) has many appealing applications. However, some traditional IBE schemes may not be secure in the real world due to the side-channel attacks. Leakage-resilient cryptography can capture these attacks by modeling information leakage that adversary can access. WebOct 1, 2024 · We equip the Boneh and Franklin IBE (BF-IBE) and Gentry-IBE with our scheme and give the security analysis to show the accuracy and the security of it. In contrast to Chow's scheme, to generate the secret key, our approach does not require the interactive protocol which brings about much extra costs.

WebOct 1, 2024 · Abstract. Key escrow is inherent in identity based encryption (IBE) since it was first put forward by Shamir. A key generation center (KGC) or private key generator is in charge of generating the user's secret key, therefore a malicious one can decrypt any ciphertext without being found. This paper introduces a new scheme to eliminate key ... WebGentry-IBE [18] uses exponent inversion in the key. Its security reduction is tight but is based on a q-type assumption. Comparatively, the security proof of the commutative blinding family has a security loss of a factor of q, while using static assumption.

WebDec 20, 2015 · The security of the Gentry IBE system is based on a q -type decisional assumption, where q refers to the number of private key queries made by an adversary. With Gentry’s all-and-any strategy, a reduction algorithm can create only one private key for each identity, which is determined by a tag component.
