Keynote: Trust Enhanced Secure Role-based Access Control on Encrypted Data in Cloud

Abstract

In this talk I will begin with a brief look at current trends in the technology scenery and some of the key security challenges that are impacting on business and society. In particular, on the one hand there have been tremendous developments in cyber technologies such as cloud, Big Data and Internet of Technologies.

Then we will consider security and trust issues in cloud services and cloud data. In this talk, we will focus on policy based access to encrypted data in the cloud. We will present a new technique, Role based Encryption (RBE), which integrates cryptographic techniques with role based access control. The RBE scheme allows policies defined by data owners to be enforced on the encrypted data stored in public clouds. The cloud provider will not be able to see the data content if the provider is not given the appropriate role by the data owner. We will present a practical secure RBE based hybrid cloud storage architecture, which allows an organisation to store data securely in a public cloud, while maintaining the sensitive information related to the organisation’s structure in a private cloud.

Then we will consider trust issues in RBE based secure cloud data systems. We will discusstwo types of trust modelsthat assist (i) the data owners/users to evaluate the trust on the roles/role managers in the system as well as (ii) the role managers to evaluate the trust on the data owners/users for when deciding on role memberships. These models will take into account the impact of role hierarchy and inheritance on the trustworthiness of the roles and users. We will also consider practical application of the trust models and illustrate how the trust evaluations can help to reduce the risks and enhance the quality of decision making by data owners and role managers of the cloud storage services.


Keynote: Transparency, Privacy and Trust – Technology for Tracking and Controlling my Data Disclosures: Does this work?

Abstract

Transparency is a basic privacy principle and social trust factor. However, in the age of cloud computing and big data, providing transparency becomes increasingly a challenge.
I will discuss privacy requirements of the General Data Protection Regulation (GDPR) for providing ex-post transparency and present how the transparency-enhancing tool Data Track can help to technically enforce those principles. Open research challenges that remain from a Human Computer Interaction (HCI) perspective will be discussed as well.


Dinner Speech: Are we doing it right?

Abstract

It’s been more than 20 years now since Computational Trust was ‘born,’ and there has been a great deal of work done in the area – trust models galore, deep understanding of applications, attacks and defences, and continual improvements on the journey.

Sometimes, though, I look at this and wonder if we are doing it ‘right.’ How do we know that the models are working, and for whom? Testbeds aside (of which there are a few, with their own issues), how can we tell if the models make the difference we want them to? When the models fail, or are applied differently, do they do a good job, are they graceful, and who gets affected (or hurt)?

This talk is about this: Steve’s First Law of Computing (no narcissism here then!) is that all computing is for people: somewhere along the line, there will be people who are observe, use, or are directly or indirectly affected by the technology. Recently I’ve been thinking about how to take this and marry it to a few other observations about people (and other animals) to be able to think about systems that address the big question: are we doing it right?
