I've been reading up on the Ring Learning with Errors problem and the proposed attacks, in relation to homomorphic encryption. Some of the literature has been quite difficult to understand - what I want to know is if it is possible to solve this problem? And if so, what is a general outline of a possible attack? I'm quite new to this so any basic explanations would be very helpful!
Edit (thanks to user fgrieu): What are known methods to solve small instances of RLWE problems, as used or proposed in cryptography with larger parametrization?
