RLWE/PLWE equivalence for the maximal totally real subextension of the $2^{r}pq$-th cyclotomic field

Iván Blanco-Chacón anbd Lorena López-Hernanz

We prove the RLWE/PLWE equivalence for the maximal totally real subextension of the $2^{r}pq$-th cyclotomic field and discuss some of its applications to cryptoanalysis.
