In this talk I will present my Bachelors thesis in which I explore the possibility of using Password Hardened Encryption together with Attribute Based Encryption to secure files in cloud-storage scenarios. The data is encrypted when not in use, while still allowing for relatively complex access control. This makes features like groups and subdirectories possible. The scheme I describe in my thesis is derived from the Password-Hardened Encryption protocol introduced by Lai in 2018 and the Multi-Authority Attribute-Based Encryption scheme introduce by Lewko and Waters in 2011.
