I'm computer guy having trouble with cryptography.
I recently read the BGV Homomorphic encryption paper which was constructed under both LWE and RLWE assumptions.
I was implementing Threshold version of BGV encryption [AJW12] using HElib optimized under the RLWE assumption, and I found out that [AJW12] proved the security under the LWE assumption.
A paper [LN16] says that the RLWE is a special instance of the LWE problem.
So, I think that [AJW12] encryption under RLWE parameters is still secure, but I'm not sure.
Am I right?
