Collusion-Deterrent Threshold Information Escrow
[article]
2021
IACR Cryptology ePrint Archive
Preserved Fulltext
Using a novel combination of oblivious transfer, robust bit watermarking, and secure multi-party computation, CDE ensures that whenever the agents collude to prematurely decrypt the user data, there would ...
By raising the bar for collusion significantly, this work offers an important step towards weakening the strong noncollusion assumption pervasive across multi-party computation applications. ...
We also thank Simon Heinzel for his efforts with a preliminary manuscript associated with this work. ...

We focus on the prominent privacy-preserving computation task of multi-server 1-private information retrieval (PIR) that inherently assumes no pair-wise collusion. ...
A long line of research on secure computation has confirmed that anything that can be computed, can be computed securely using a set of non-colluding parties. ...
In fact, it is fair to say that, the entire field of secure multi-party computation (MPC) [9] , [93] relies on the non-collusion assumption. ...
