RLWE and PLWE over cyclotomic fields are not equivalent
Antonio J. Di Scala, Carlo Sanna, Edoardo Signorini
We prove that the Ring Learning With Errors (RLWE) and the Polynomial Learning With Errors (PLWE) problems over the cyclotomic field are not equivalent. Precisely…

Antonio J. Di Scala, Carlo Sanna, Edoardo Signorini
Recently, Blanco-Chacón proved the equivalence between the Ring Learning With Errors and Polynomial Learning With Errors problems for some families of cyclotomic number fields by g…
