  •  Timo Kasper, Sweet Dreams and Nightmares: Security in the Internet of Things
    ABSTRACT: Wireless embedded devices are predominant in the IoT: Objects tagged with RFID and NFC technology, smartphones, and other embedded tokens interact from device to device and thereby often process information that is security or privacy relevant for humans. For protecting sensitive data and preventing attacks, many embedded devices employ cryptographic algorithms and authentication schemes. In the past years, various vulnerabilities have been found in commercial products that enable to bypass the security mechanisms. Since a large number of the devices in the field are in the hands of potential adversaries, implementation attacks (such as side-channel analysis and reverse engineering) can play a critical role for the overall security of a system. At hand of several examples of assailable commercial products we demonstrate the potential impact of the found security weaknesses and illustrate "how to not do it".
    Timo Kasper studied electrical engineering and information technology at the Ruhr-University Bochum and at the University of Sheffield, UK. In 2006, his Diploma thesis "Embedded Security Analysis of RFID Devices" won the first place award for IT security (CAST, Darmstadt). Timo Kasper has been research assistant at the Chair for Embedded Security of the Horst Görtz Institute for IT Security (HGI) since October 2006. He completed his studies 2011 with a PhD in Engineering. In 2012, his PhD thesis "Security Analysis of Pervasive Wireless Devices - Physical and Protocol Attacks in Practice" won the first place award for IT security (CAST, Darmstadt). Timo is co-founder of Kasper & Oswald GmbH offering innovative products and services for security engineering.
    His field of research covers the security of embedded cryptographic systems such as smartcards, microcontrollers, and FPGAs, with a focus on RFID and wireless applications. Timo Kasper has experience with security analyses and penetration testing, implementation attacks (side-channel analysis, fault injection), reverse engineering, and system-level approaches such as man-in-the-middle attacks. He is skilled in implementing cryptography on embedded systems and efficiently securing them with countermeasures. His publications demonstrate various security vulnerabilites of real-world applications, e.g., by breaking an access control system (KeeLoq, Crypto 2008), a payment system (Financial Crypto 2010), and the security mechanism of widespread FPGAs (ACM CCS 2011).

  • Bart Preneel, Lightweight and Secure Cryptographic Implementations for the Internet of Things.
    ABSTRACT: There is a growing insight that if we build Internet functionality into every object, it will be essential for broad acceptability that security and privacy features are protected from day one.  The old approach of first rolling out the system and thinking about security and privacy later will no longer work. Cryptographic algorithms form an essential element to protect the Internet of Things; moreover, this environment will impose ever higher requirements for the algorithms in terms of performance, security, and cost. For many settings algorithms tradeoffs are expected that offer an improvement of one order of magnitude compared to existing standards. The talk will present an overview of the issues that need to be addressed for such an optimization to be successful.

  • Paul England, TPM2.0.
    ABSTRACT: TPM2.0 This talk is an introduction to the architecture and use of TPM2.0 - the new Trusted Platform Module. TPM2.0 fixes and regularizes some of the behaviors in earlier devices, as well as adding algorithm agility and simplifying device and key management. I’ll describe the capabilities of the new TPM including one or two of the novel new features. TPM2.0 is unique in specifications of this kind in that it is machine readable and executable. This feature has been used by vendors to build "real" TPM devices, but this also means that anyone can use tools to take the specification apart and build new things like TPM-simulators and testers. I’ll describe the structure of the executable specification, and how we used these techniques to develop some open-source TPM-programming libraries.
    Paul England is a Software Architect at Microsoft. He has worked on many platform security technologies over the last decade or so: He co-invented sealing and attestation, and then led the incorporation of these technologies into the original TPM specification. He also designed - and then worked with hardware partners to deliver - several of the newer secure-boot and isolation technologies that are now common in CPUs. He currently runs a research and incubation group investigating security, storage and networking. On the security side, recent successes have included editing the new TPM2.0 specification, helping with the Windows-8 TPM-related security features, and working with hardware partners to incorporate TPMs at low cost into many current microprocessors. Prior to Microsoft Paul was manager of a team of researchers and technologists at Bell Communications Research (Bellcore). He worked on early web services, distributed systems, high-performance computing and multimedia servers.Paul has a Ph.D. in physics from Imperial College London, and a B.Sc. in physics from the University of Birmingham.

  • Pierangela Samarati, Data Protection in the Cloud.
    ABSTRACT: The rapid advancements in Information and Communication Technologies (ICTs) have enabled the emerging of the "cloud" as a successful paradigm for conveniently storing, accessing, processing, and sharing information. With its significant benefits of scalability and elasticity, the cloud paradigm has appealed companies and users, which are more and more resorting to the multitude of available providers for storing and processing data. Unfortunately, such a convenience comes at a price of loss of control over these data and consequent new security threats that can limit the potential widespread adoption and acceptance of the cloud computing paradigm. In this talk I will illustrate some security and privacy issues arising in the cloud scenario, focusing in particular on the problem of guaranteeing confidentiality and integrity of data stored or processed by external providers.
