Bachelor@IAIK 2022/23

We present our new open bachelor’s thesis topics and award prizes to excellent students who contributed to scientific publications this past year.

If you’re interested in joining us for your bachelor’s thesis in security, this is the best way to get an impression of our topics as well as how a bachelor’s thesis at IAIK works: You’ll hear about our research areas and current hot topics, our Bachelor@IAIK program where you can work on your thesis together with your fellow students in one of our offices if you like, and maybe you’ll get to know your supervisor while chatting along.

The event will also be the kick-off lecture in Introduction to Scientific Working (ISW) where you will be able to choose your preferred topic!   

We are looking forward to meeting you!

 

Matchmaking Encryption

Meeting ID (access code): 2733 968 8841 Meeting password: imNugMMt623

Daniele Venturi introduced a new form of encryption that we name matchmaking encryption (ME). Using ME, sender S and receiver R (each with its own attributes) can both specify policies the other party must satisfy in order for the message to be revealed. The main security guarantee is that of privacy-preserving policy matching: During decryption nothing is leaked beyond the fact that a match occurred/did not occur. ME opens up new ways of secretly communicating, and enables several new applications where both participants can specify fine-grained access policies to encrypted data. For instance, in social matchmaking, S can encrypt a file containing his/her personal details and specify a policy so that the file can be decrypted only by his/her ideal partner. On the other end, a receiver R will be able to decrypt the file only if S corresponds to his/her ideal partner defined through a policy. On the theoretical side, we define security for ME, as well as provide generic frameworks for constructing ME from functional encryption. These constructions need to face the technical challenge of simultaneously checking the policies chosen by S and R, to avoid any leakage. On the practical side, we construct an efficient identity-based scheme for equality policies, with provable security in the random oracle model under the standard BDH assumption. We implement and evaluate our scheme and provide experimental evidence that our construction is practical. We also apply identity-based ME to a concrete use case, in particular for creating an anonymous bulletin board over a Tor network.

IAIK Christmas Special 2020

The “IAIK Christmas Special” is a yearly unique show that reviews what happened in InfoSec in 2020 and showcases recent hacks and exploits. With 300-500 viewers in a packed lecture hall, it cannot take place offline this year – now it takes place online and we will make it a better and greater show than any year before.

We invited 5 InfoSec guests, a music live act, and of course, most importantly: exciting hacks, exploits, and demos.

This special lecture is part of the TU Graz SSD and InfoSec courses.
