.@SPIES_UAB has N = 3 total papers accepted to ASIACCS 2021 (1 in round 2, and 2 earlier in round 1 as below: EchoVib and HVAC).

Details about the new paper will appear shortly! @Mohammedjabour @prakash2120 @jaysprakash

Paper accepted to @IEEEEUROSP 2021. Joint work with @prakash2120 and collaborators from Syracuse University.
We present a low-effort, strong and "biometric-less" wearable 2FA scheme based on short, simple and "memory-free" special sequence typing gestures. Details will follow.

[Nitesh Saxena @saxenaTAMU]

.@SPIES_UAB and collaborators will have 3 papers presented @ACSAC_Conf on Friday:

(1). IvoriWatch
(11:30am, 6A: Embedded System and IoT Security)

(2). WearID and (3). Voicefox
(1pm, 7A: Security of Voice Assistants)

[Nitesh Saxena @saxenaTAMU]

Excellent selection!

The @SPIES_UAB has 3 papers here: IvoriWatch, Voicefox and WearID. Stay tuned for pre-prints.

Too bad, Twitter, you should have been using Hacksaw to save the big disgrace. Never mind, it's not too late still :-)

Seriously, high time we move beyond "entry-point only authentication"!

Hacksaw shows a way forward (NOT a finished product yet!).

"Hacksaw" accepted as a full-paper to WiSec'20. A transparent and privacy-preserving continuous web authentication scheme based on a wrist-worn wearable device (e.g., watch, bracelet). W/ @saxenaUAB

Privacy is important, but accuracy and security likely more so. A take by UAB News based on my group's work on the proximity detection problem over the last decade.

Prakash Shrestha (@prakash2120) successfully defended his PhD dissertation today ("New Authentiation and Privacy Paradigms in Mobile and Wearable Computing"). Great work, hard problems, many top papers (1 CCS, 1 NDSS, 2 Wisec, ACSAC, CSUR and more), Dean's award, etc.

Prakash Shrestha @prakash2120 wins the Dean's Award for Outstanding Graduating PhD Student at the Honors Convocation today. Congratulations!

Nothing feels better than your students standing tall along with you (and your daughter running towards you as you pose :-))

[Nitesh Saxena @saxenaTAMU]

However, there is still hope for a method that reduces user effort while retaining strong security. Our listening-watch paper from WiSec'18 is a serious attempt in that direction. See: https://t.co/ovjsuS1eiW

[Nitesh Saxena @saxenaTAMU]

- In our CCS'18 "Sound-Danger" paper (https://t.co/mswFlN979B), we had shown that TFA based on ambient sounds (Sound-Proof or alike) is insecure. [The authors in the ACSAC'18 paper above seem to cite our attack, but are accidentally referencing a different paper!]

Prakash Shrestha @prakash2120 presenting our Listening-Watch paper at Wisec. We show how to minimize user effort in second factor authentication while still retaining high security. Our earlier work from CCS'16 had shown the vulnerabilities of other low-effort TFA schemes.
