ePrint Report: Homomorphic Evaluation of LWR-based PRFs and Application to Transciphering
Amit Deo, Marc Joye, Benoit Libert, Benjamin R. Curtis, Mayeul de Bellabre
Certain applications such as FHE transciphering require randomness while operating over encrypted data. This randomness has to be obliviously generated in the encrypted domain and remain encrypted throughout the computation. Moreover, it should be guaranteed that independent-looking random coins can be obliviously generated for different computations.
In this work, we consider the homomorphic evaluation of pseudorandom functions …
