Abstract
It is becoming more common for companies to outsource their need for data storage to storage-as-a-service (STAAS) providers, also known as cloud services. The STAAS provider is responsible for safeguarding and keeping data accessible for its customers. However, this means that the customers needs to have a certain level of trust for the provider regarding several security related aspects, something which they may not have or are legally allowed to.<br/> <br/> In a potential cloud service we want to overcome the need of a trust-based relationship between the service provider and its customers. It should be possible for a customer to store its data without the concern of unauthorised access while at the same time data should be easy to distribute without disclosing the private key. We want to look further into the technique of proxy re-encryption, among other techniques, in order to keep data encrypted from endpoint to endpoint while simultaneously ensuring that this operation is feasible in both time and memory. This since the vast majority of the data that is to be stored in this STAAS is video material and therefore relatively large in size. Our goal is to assess if there is a possible encryption/decryption solution in which the customer is in full authority of access control and is realistic to use performance wise.
