The paper begins by describing the current problems of the PEC and try to solve the problem of identifying and retrieve the list of the authorized PEC domains avoiding the use of a centralized system, but taking advantage of the infrastructure of the secure DNS, DNSSec, in order to standardize the method. After a brief discussion of the standards DNS and DNSSec, and the introduction of standards for the publication of X.509v3 certificates inside the DNSSec itself, proposed with RFC6698 by the IETF's DANE group, the technical report introduces the proposed modifications, using a small case study to exemplify them. Finally there is a section analysis of the costs and benefits introduced by the proposal. 2014-09-15 info:eu-repo/semantics/report http://puma.isti.cnr.it/dfdownloadnew.php?ident=cnr.isti/cnr.isti/2014-TR-043 it TR.
