报告题目: Public Key Encryption with Keyword Search against Insider Attack

摘要: The ciphertext retrieval is of paramount importance for data confidentiality and utilization. Thanks to bilinear-pairing-based cryptography, searching in an encrypted data has become a reality. The most common application of searchable encryption is cloud storage systems, where an honest-but-curious server manages the storage system and is able to find correct text from an encryption without decrypting it. Although the security against outsiders can be achieved, the most challenging task is to resist the so-called insider attack from the untrusted cloud storage server, who can actively guess the encrypted text with high probability. In this talk, the security models of searchable encryption such as secure channel free and insider attack will be discussed. A novel framework to resist inside attacks will be introduced. In addition, a discussion will be presented to show how to reduce the computational cost of searchable encryption with pre-computation.

报告题目: 基于身份的云数据审计

摘要: 云存储服务大大减轻了用户的数据管理负担。然而,云服务提供商不是完全可信的,数据在云端是否完好保存即云数据完整性成为用户最大的担忧。云数据审计协议是一种在无需下载云数据的前提下实现云数据完整性检测的轻量型协议。报告介绍简化密钥管理的云数据审计协议:基于身份云数据审计协议;内容包括对现有协议的分析,以及提出的一般性构造和具有数据隐私保护的新型构造。
