comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

Foreword
This document (CEN/TS 16326:2013) has been prepared by Technical Committee CEN/TC 331 “Postal
services”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
Keeping pace with the changing communications market, postal operators are increasingly using new
communication and information technologies to move beyond what is traditionally regarded as their core
postal business. They are meeting higher customer expectations with an expanded range of products and
value-added services.
Standards are important prerequisites for effective postal operations and for interconnecting the global
network. The European Committee for Standardization, their Technical Committee 331 "Postal Services"
develops and maintains a growing number of standards to improve the exchange of postal-related information
between postal operators, postal handling organisations, customers, suppliers and other partners, including
various international organisations.
This functional specification has been developed in close relationship with the following technical standards:
 CEN/TS 15121-1:2011;
 ETSI TS 102 640-1.
The use of this Technical Specification as a basis for any implementation is at the risk of the user. Any party
intending such use is strongly advised to seek close contact with the appropriate working group, so that it can
be kept informed of ongoing work.
The CEN/TS 16326 was originally published as a UPU standard S52-1and was adopted by CEN under the
current Memorandum of Understanding between UPU and CEN.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany,
Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
Introduction
This document describes the functional specification for a postal operator to build or implement the postal
registered electronic mail (abbreviated hereinafter to PReM) system which can be offered to the customers of
the postal operator as part of the Secure electronic Postal Services (SePS).
PReM is an electronic version of the traditional postal registered mail service. It uses state-of-the-art
cryptographic technologies to provide strong role authentication, protection of message confidentiality and
integrity and to add non-repudiation attributes to evidence of events and operations. Therefore, the goal of a
PReM is to enhance the traditional e-mail service so as to provide an end-to-end trusted electronic
communication service, encompassing both evidence of submission and delivery between authenticated
parties.
The service is embodied in the secured and trusted exchange of electronic mail, as every step of the process
is logged for future evidence tracing and any entity involved is authenticated. The PReM service comprises
the following features:
— secured message forwarding and delivery: ensures the PReM Message confidentiality (encryption)
and integrity (no modification); and authenticity and non-repudiation of users (mailer and addressee)
and postal operators (origin and destination). In addition, PReM messages will be securely
transported from mailer to addressee/mailee;
— evidence generation: all significant events within a complete operation cycle are traceable. Types of
evidence and evidence formats are described in 7.2;
— event notification: notification that a particular event/operation has occurred will be generated and
sent to corresponding parties;
— archival of evidence: storage of generated evidence for future attestation.
The implementation of part or all of this functional specification might involve the use of intellectual property
which is the subject of patent and/or trademark rights. Since the specification was developed in close
relationship with ETSI TS 102 640, these might include rights held by ETSI. It is the responsibility of users of
the standard to conduct any necessary searches and to ensure that any pertinent rights are in the public
domain, are licensed, or are avoided. CEN/TC 331 cannot accept any responsibility in case of infringement,
