I am a postdoctoral scholar — UCSD CSE fellow working with Nadia Heninger and Deian Stefan. I received my PhD in ECE and MSc in CS from WPI under the supervision of Berk Sunar and Thomas Eisenbarth. I work on computer security and privacy, microarchitectural security, side channels and cryptanalysis, and architectural security primitives. I have also interned at Cisco Talos working on fuzz testing for automated vulnerability discovery, and Qualcomm product security initiative (QPSI) working on system-level security of PCIe controllers.

CVEs & Security Advisories

Intel

• INTEL-SA-00241/CVE-2019-11090 Cryptographic timing conditions in the subsystem for Intel(R) PTT before versions xxx; Intel(R) TXE xxx; Intel(R) SPS before versions xxx may allow an unauthenticated user to potentially enable information disclosure via network access.
• INTEL-SA-00233/CVE-2018-12126 Microarchitectural Store Buffer Data Sampling (MSBDS): Store buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.
• INTEL-SA-00238/CVE-2019-0162 Memory access in virtual memory mapping for some microprocessors may allow an authenticated user to potentially enable information disclosure via local access.
• INTEL-SA-00106/CVE-2018-3691 Intel Integrated Performance Primitives Cryptography Library before version 2018 U2.1 does not properly ensure constant execution time.
• INTEL-SA-00135 Intel SGX SDK and Platform Software (PSW) utilize the Intel IPP Cryptography Library.  Vulnerabilities in this library have been reported that may enable a local attacker utilizing software-based side channels to recover certain cryptographic keys.
• INTEL-SA-00202/CVE-2018-12155 Data leakage in cryptographic libraries for Intel(R) IPP before 2019 update 1 release may allow an authenticated user to potentially enable information disclosure via local access.

STMicroelectronics

• CVE-2019-16863 STMicroelectronics ST33TPH* TPM 2.0 devices before 2019-09-12 allow attackers to extract the ECDSA private key via a side-channel timing attack because ECDSA scalar multiplication is mishandled, aka TPM-FAIL.

WolfSSL

• CVE-2019-19960 In wolfSSL before 4.3.0, wc_ecc_mulmod_ex does not properly resist side-channel attacks.
• CVE-2019-19961 In wolfSSL before 4.3.0, RSA key generation uses the non-constant-time BEEA modular inversion algorithm during the generation of RSA private key parameters, allowing attackers to leak the RSA key via a side-channel attack.
• CVE-2019-19962 In wolfSSL before 4.3.0 mishandles calls to wc_SignatureGenerateHash, leading to fault injection in RSA cryptography.
• CVE-2019-19963 In wolfSSL before 4.3.0, DSA signing uses the BEEA algorithm during modular inversion of the nonce without blinding, leading to a side-channel attack against the nonce.
