Securing Public Cloud Storage with Protection against Malicious Senders

公有云存储为中小企业提供了低成本的解决方案。然而，云数据泄露是一个主要问题。在将数据存储在云中之前，使用安全策略对数据进行加密并不能解决问题，因为存在恶意发送者，这些发送者故意让加密的数据超出描述的策略进行访问。该项目旨在通过开发新的实用加密解决方案来实现安全的公共云存储，该解决方案提供针对恶意发送者的保护，而不是现有的只能应对恶意接收者的知识。预期的结果是创新技术，这些技术将降低基础设施成本，并为云存储提供网络安全。

Public cloud storage offers low-cost solutions for small and medium-sized enterprises. However, cloud data leakage is a major concern. Encrypting data with a security policy before storing in the cloud does not solve the problem due to the presence of malicious senders who deliberately make encrypted data accessible beyond the described policy. This project aims to enable secure public cloud storage by developing new practical cryptographic solutions that provide protection against malicious senders, in contrast to the existing knowledge that can only cope with malicious receivers. The expected outcomes are innovative technologies, which will lower infrastructure costs and provide cybersecurity for cloud storage.
