* ABSTRACT:<br />An advanced metering infrastructure is an integrated system of smart meters, communications networks and data management systems that support the safe, efficient and reliable distribution of electricity while providing advanced functionality to energy customers. Unfortunately, sophisticated cyber attacks on advanced metering infrastructures are a clear and present danger.  A chilling scenario involves a computer worm that traverses advanced metering infrastructures, shuts off power and permanently disables millions of smart meters.<br /><br />This presentation describes the results of security analyses of four large advanced metering infrastructures, one  with a point-to-multipoint topology and three with mesh topologies.  The research articulates the attack surfaces of the point-to-multipoint and mesh advanced metering infrastructures. Additionally, it identifies potential targets, and describes novel attacks on principal components in the four advanced metering infrastructures. Finally, the research clarifies the security impacts of attacks enabled by physical access, along with techniques for mitigating the attacks. While the attacks, impacts and mitigation techniques pertain to the four advanced metering infrastructures in the case study, they are relevant to advanced metering infrastructures in general.

  • ABSTRACT:
    Protecting data in-use has long been a challenging open problem in computer science. While being computed on in cleartext in system memory, your data stored in RAM is exposed to the millions lines of code that make up the underlying platform’s privileged system software. By design, a malicious firmware, or compromised operating system can easily leak your data, or compromise its integrity.

    Confidential computing is a privacy-enhancing system security primitive which addresses this challenge head-on, by running your security-sensitive processes in isolated execution environments whose security guarantees can be remotely attested. Its recent generations, such as Intel SGX, Intel TDX and AMD SEV SNP, make use of newer CPU hardware and architectural extensions, such as the AES-128 hardware encryption engine which encrypts RAM memory pages in real-time. Hardware with these capabilities is already available in the market, and public cloud providers have been one of its early adopters.

    In this presentation, we first visit the history of confidential computing, then study the technical system primitives which allow us to implement both isolation and attestation. We also explore the different silicon implementations of confidential computing, where they are deployed today, and for which uses cases.
