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. We give the rst dual-system IBE which has both the key structure based on the exponent http://www.ijnc.org/index.php/ijnc/article/view/228

Web第一个基于格的IBE方案由Gentry等[7]提出，是基于 Dual-Regev加密算法设计的。后来，有学者对此进行了研究和改进。2010年，Agrawal等[8]构建了基于格的IBE方案，称为ABB方案，他们使用的公钥矩阵是由两部分组成，私钥是分两步骤采样而得的，虽然后来有很多学者都 ... 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. To overcome this issue, inspired by the Rand-RCCA-secure scheme of Prabhakaran and Rosulek [24], we conduct further speci c treatments on adjusting the original Gentry-IBE. lake town kolkata map https://nevillehadfield.com

WebIdentity-based encryption (IBE) [52] is an extension of PKE in which an arbitrary string, such as email, location information, and biometrics information, is considered to be a public key, and is standardized by the ISO/IEC 18033-5 and IEEE P1363.3. 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.

WebInterestingly, Gentry and Halevi [16] recently showed how to extend these concepts to get a fully secure HIBE system, although this system actually used an even more involved assumption. In addition, the “jump” from Gentry’s IBE to the HIBE system added a significant amount of complexity to the system and proofofsecurity. Our Contribution.
