Web

Most of the data on the websites we use is stored on servers in plaintext, and server-side programs authenticate users’ identities and grant user access permissions. However, as business logic becomes more complex, there are always various vulnerabilities, even sensitive applications like Alipay are no exception. In addition, more and more websites are being built on public cloud platforms, a major concern is: Will the owner of the cloud platform steal my confidential data?

Therefore, it is best to encrypt data stored on the server, and the decryption key is in the user’s hands, that is, only the user can see the plaintext, and the website owner, cloud service provider, and possible server intruders can only see the ciphertext. Building web applications on top of encrypted data using Mylar, which will be published at the top conference in the network field NSDI 2014, is such a solution.
