About a week ago, I had the great opportunity to attend USENIX FAST 2025 and present some of our ongoing work optimizing security protocols for cloud storage. It was my first time attending—big thanks to the organizers for putting together a fantastic program. 🎉 A high-level summary for anyone who might be interested: Protecting the integrity of data stored in the cloud is an important element of cloud security. However, integrity checking protocols introduce significant performance overheads—and those overheads increase both as our security needs grow and as our systems scale. Our work takes a first-principles approach to: 1) characterizing the root cause of integrity overheads to understand performance bottlenecks, and 2) breaking through performance ceilings with optimization techniques and adaptive data structure design. We looked at block storage in the context of confidential virtual machines but the insights transfer broadly—exciting times ahead for confidential computing!

@VSehwag_ @prateekmittal_ @PurduePresident @orussakovsky Congratulations!

Defended my PhD thesis today 🎉! Thanks @prateekmittal_ and @PurduePresident for being the amazing advisers. Suman Jana, @orussakovsky, Niraj Jha - thank you joining the thesis committee. It was a wonderful journey at Princeton.

@iamgroot42 @CS_UVA @UdacityDave Congratulations!! Well deserved!

Received the 'John A. Stankovic Graduate Research Award' from @CS_UVA for "excellence in research". All thanks to my extremely encouraging and helpful advisor @UdacityDave ! #gradlife #researchlife

Pleased to announce that @FKoushanfar and myself will be co-chairing the @NSF SaTC Vision 2.0 workshop on March 8-9th. We are calling for nominations for attendees and discussion topics (Deadline February 10th). More info: cdis.wisc.edu/satc2/ @WisconsinCS @uwcdis @UWMadisonLS

Happy to have given the keynote at @acm_ccs on the critical importance of cyber-security to achieving sustainability goals - great discussion! Looking forward to seeing papers in security conferences on sustainability. For folks looking for the slides: patrickmcdaniel.org/pubs/ccs22.pdf

Congrats to the six Computer Sciences MS/PhD students who were selected as LEAP Alliance Fellows, including @_quinnburke @jearbear154 @RyanSheatsley and others!! Learn more about the program here: go.wisc.edu/90hcww @cmdit @uwcdis @UWMadisonLS

I am looking to recruit students at UIUC (deadline: Dec 15, 2022). More details (about me/my research interests) are on my webpage. RTs are appreciated!

The results show that attack performance is highly contextual (e.g., attacks that perform best on one dataset may be surprisingly suboptimal on another).

To identify the most effective components for a given context, we leverage hypothesis testing and find many hypotheses with extreme significance (exhibiting 64-bit underflow!).

I am pleased to announce that our paper, The Space of Adversarial Strategies, has been accepted to @USENIXSecurity '23! This work is jointly led by @blaine_hoak and myself, as well as in collaboration with @EricPauley_ and @pdmcdan. Here's the link: arxiv.org/abs/2209.04521

@VarunChandrase3 @ECEILLINOIS @ecekamar Congratulations Varun!!

I'm delighted to announce that I'll be joining @ECEILLINOIS as an assistant professor in Fall 2023. I'll be looking for students (in both CS + ECE). I'll be spending a year with @ecekamar 's group at MSR till then (1/n)

I am happy to announce that after 18 great years at Penn State I will be moving to the University of Wisconsin-Madison (@UWMadison), joining as the Tsun-Ming Shih Professor in the Dept. of Computer Sciences (@WisconsinCS).

@NicolasPapernot Congratulations!!!!

Pleased to share that our paper on the risks of IP address reuse in public clouds has been accepted to @IEEESSP! (1/10)

@SamAlbanesi Congratulations!!!

As we turn our attention to the upcoming @acm_ccs deadline, a reminder that SIGSAC elections are underway. I'm asking for your vote as chair and to vote @mmazurek_ for vice-chair and @kcotsneb for treasurer. Let me talk about our platform (cise.ufl.edu/~butler/acm-pl…). (1/8)
