Understanding Key Switching in CKKS

FHE Questions
1

Hi all,

I’m looking to understand key switching / relinearization for the RNS-CKKS scheme especially in OpenFHE, particularly the hybrid method. What is the best paper to look at that matches up with the implementation in OpenFHE?

Thank you

This paper includes the Hybrid Key Switching algorithm that is implemented in OpenFHE.
