论文摘要
最近，印度政府采取了几项倡议，使印度具有数字强大，例如为每个居民提供一个独特的数字身份，称为Aadhaar，并提供了基于Aadhaar（例如Digilocker）的几种在线电子政务服务。 Digilocker是一款在线服务，为其订户提供了公共云上可共享的私人存储空间。尽管Digilocker确保了传统的安全性，例如数据完整性和安全数据访问，但尚未解决电子信息的隐私。基于Ciphertext-Policy属性的加密（CP-ABE）可以改善数据隐私，但正确的实施始终是一个挑战。本文提出了一种使用CP-ABE实施隐私增强的Digilocker的计划。
Recently, Government of India has taken several initiatives to make India digitally strong such as to provide each resident a unique digital identity, referred to as Aadhaar, and to provide several online e-Governance services based on Aadhaar such as DigiLocker. DigiLocker is an online service which provides a shareable private storage space on public cloud to its subscribers. Although DigiLocker ensures traditional security such as data integrity and secure data access, privacy of e-documents are yet to addressed. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) can improve data privacy but the right implementation of it has always been a challenge. This paper presents a scheme to implement privacy enhanced DigiLocker using CP-ABE.
