<p><b>Since end of 2018, I have joined Netflix as a Senior Security Engineer in California.</b>
</p>At Netflix, I co-lead the PKI strategy efforts, co-own the TLS certificate lifecycle management service, and partner with cross-functional teams to help with secure system design aspects.<p>
</p><p>
Prior to that I was a researcher at ETH Zurich, Switzerland, affiliated with the <a target="_blank" href="http://www.vs.inf.ethz.ch/">Distributed Systems Group</a>.
My research focus has been on enabling the vision of data ownership, where users retain control over their data, and service providers only see and process encrypted data.
More specifically, I have designed and built encrypted data processing, and cryptographic-based authorization systems.
In general, I follow research in the systems, networking, and security domain.
</p><p>
I obtained my Ph.D. from ETH Zurich in summer 2018.
The title of my dissertation is "Retaining Data Ownership in the Internet of Things" (<a target="_blank" href="http://www.vs.inf.ethz.ch/publ/papers/mshafagh_dissertation_2018.pdf">PDF</a>) and
my examination committee consisted of Prof. <a target="_blank" href="http://csl.stanford.edu/~pal/">Philip Levis</a> and my co-advisers Prof. <a target="_blank" href="http://www.syssec.ethz.ch/people/capkun.html">Srdjan Capkun</a> and Prof. <a target="_blank" href="https://people.inf.ethz.ch/mattern/">Friedemann Mattern</a>.

<h4>TimeCrypt: A Scalable Private Time Series Data Store</h4>
<div id="image" style="margin: 0px 10px 10px 0px; float: left;">
<img width=200px src="images/TimeCrypt.png">
</div>
<pr>
Today, a growing number of services collect detailed time series data that is stored in the cloud. Protecting the confidentiality of this vast and continuously generated data, while preserving its utility, is crucial for many applications in this space. TimeCrypt is a system we designed that provides scalable and real-time analytics over large volumes of encrypted time series data. To enable granular access control and efficient analytics over large encrypted streams, we introduce a new encryption-based access control construction that is additively homomorphic. TimeCrypt supports rich functionalities and access control semantics needed for time-series data. In TimeCrypt, data is encrypted end-to-end, and authorized parties can only decrypt and verify queries within their authorized access scope.

<pr>
Secure storage and management of data generated by the myriad of IoT devices present new challenges in the cloud era.
How do we empower the user with ownership and fine-grained access control for IoT data without sacrificing performance or security?
To address this challenge, we design <a target="_blank" href="dropletchain.github.io">Droplet</a> a novel decentralized data access control service, which operates without intermediate trust entities.
We leverage the blockchain technology to bootstrap trust, for a decentralized, secure, and resilient access control management.
Droplet handles time series data, enables reliable sharing among heterogeneous applications from different trust domains, and features a cryptographically-protected fine-grained and scalable access control to data streams.
<a target="_blank" href="https://arxiv.org/pdf/1806.02057.pdf">PDF</a>
<br></br>
We have implemented three apps on top of Droplet: Fitbit activity tracker, Ava health tracker, and ECOviz smart meter dashboard.

<h4>Pilatus: Partially Homomorphic Encrypted Sharing for IoT Data</h4>

<pr>
IoT applications often utilize the cloud to provide storage and ubiquitous access to collected data. This naturally facilitates data sharing with third-party services and other users, but bears privacy risks, due to data breaches or unauthorized trades with user data. To address these concerns, we present Pilatus, a new data protection platform tailored for the IoT ecosystem, that protects data confidentiality while enabling secure processing and selective sharing of encrypted data. Our solution includes a suite of novel techniques that enable efficient partially homomorphic encryption, re-encryption and decryption. Pilatus grants users low-level control over their cloud data with cryptographic guarantees. Pilatus features a novel encrypted data sharing scheme with revocation capabilities and in situ key-update. We present performance optimizations that make these advanced cryptographic tools practical for mobile platforms.

<h4>Talos: Encrypted Data Processing for the IoT</h4>

<img width=200px src="images/Talos.png">
</div>
<pr>
To tackle the data privacy concerns in IoT, we introduce Talos, a system that stores IoT data securely in a Cloud database while still allowing query processing over the encrypted data.
We enable this by encrypting IoT data with a set of cryptographic schemes such as order-preserving and partially homomorphic encryption.
To achieve this in constrained IoT devices, Talos relies on optimized algorithms that accelerate order-preserving and partially homomorphic encryption by 1 to 2 orders of magnitude.
We assess the feasibility of Talos on low-power devices with and without cryptographic accelerators and quantify its overhead regarding energy, computation, and latency.
With a thorough evaluation of our prototype implementation, we show that Talos is a practical system that can provide a high level of security with a reasonable overhead.

<h4>Proximity-based Authentication for the Internet of Things</h4>
<div id="image" style="margin: 0px 10px 10px 0px; float: left;">
<img width=200px src="images/attacker_model.jpg">
</div>
<p>
In this project, we introduce a proximity-based authentication approach
for the IoT that works in-band
by solely utilizing the wireless communication interface. The
novelty of this approach lies in its reliance on ambient radio
signals to infer proximity within about one second, and in
its ability to expose imposters located several meters away.
We identify relevant features sensed from the RF channel to
establish a notion of proximity across co-located low-power
devices. We introduce our proximity-based authentication
protocol and show the feasibility of our approach with an
early prototype using off-the-shelf 802.15.4 sensors.

<h4>Low-power Wireless Systems Coexistence</h4>
<div id="image" style="margin: 0px 10px 10px 0px; float: left;">
<img width=200px src="images/TIIM.png">
</div>
<p>
The rise of heterogeneity in wireless technologies operating
in the unlicensed bands has been shown to adversely affect
the performance of low-power wireless networks. CrossTechnology
Interference (CTI) is highly uncertain and raises
the need for agile methods that assess the channel conditions
and apply actions maximizing communication success.
To tackle the challenges of CTI, we design and build cognitive systems that can detect CTI and apply effective counter-measures.

<h1>Teaching </h1>
<br><h4>Teaching Assistant at ETH Zurich:</h4></b>
<p>My TA role includes in general varying tasks such as designing problem sets, teaching weekly tutorial sessions, grading assignments and course projects, correction of exams, helping in designing final exams, and guiding students on presenting and writing seminar research papers.
I have been a teaching assistant for the following courses:
</p>
<ul>
<li>
<b>Informatics I for Electrical Engineers - </b> Fall
<a target="_blank" href="https://people.inf.ethz.ch/mshafagh/info1-2017/"> 2016</a>
<a target="_blank" href="https://people.inf.ethz.ch/mshafagh/info1-2017/"> 2017</a>
</li>
<p>
The primary goal of this course is to teach first semester students how to program in C++.
They learn object-oriented programming and simple data structures. My role as TA includes holding weekly recitations, giving feedback on assignments, etc.
</p>
<li>
<b>Informatics II for Electrical Engineers - </b> Spring
<a target="_blank" href="http://www.vs.inf.ethz.ch/edu/FS2014/I2/">2014</a>,
<a target="_blank" href="http://www.vs.inf.ethz.ch/edu/FS2015/I2/">2015</a>,
<a target="_blank" href="http://www.vs.inf.ethz.ch/edu/FS2016/I2/">2016*</a>,
<a target="_blank" href="http://www.vs.inf.ethz.ch/edu/FS2017/I2/">2017*</a>
</li>
<p>
This course is a continuation of Informatics I, with more focus on algorithms and data structures.
The exercises are in Java and cover divide & conquer principle, recursion, sort, backtracking, trees, and other fundamental data structures.
They learn object-oriented programming and simple data structures.
My role as TA includes holding weekly recitations, giving feedback on assignments, etc.
</p>
<p>
Since 2016 I am the head TA in this course.
In 2017, we successfully integrated <a target="_blank" href="https://codeboard.io">codeboard</a> as the submission platform for student assignments.
</p>
<li>
<b>Ubiquitous Computing Seminar - </b> Fall
<a target="_blank" href="http://www.vs.inf.ethz.ch/edu/FS2014/UCS/">2014*</a>,
<a target="_blank" href="http://www.vs.inf.ethz.ch/edu/FS2015/UCS/">2015*</a>
</li>
In this class, students learn how to conduct scientific research, by reading papers and writing an overview seminar paper.
</ul>
* head TA: involves interviewing and hiring student TAs and coordinating the tutorials. In Informatics II 2017, we have more than 350 students and 14 TA.
