Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of document should be noted (see www.iso.org/directives or www.iec.ch/members_experts/refdocs).

ISO and IEC draw attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by SNIA (as TLS Specification for Storage Systems, Version 2.1) and drafted in accordance with its editorial rules. It was adopted, under the JTC 1 PAS procedure, by Joint Technical Committee ISO/IEC JTC 1, Information technology.

This second edition cancels and replaces the first edition (ISO/IEC 20648:2016), which has been technically revised.

The main changes are as follows:

— a statement has been added regarding the relevance of ISO/IEC 20648 to Datagram Transport Layer Security (DTLS) implementations;
— a statement has been added regarding quantum computing and TLS;
— a statement has been added encouraging the use of TLS 1.3;
— a recommendation has been added to guard against replay attacks on zero round-trip time (0-RTT) for TLS version 1.3;
— the recommended cipher suites have been aligned with the RFC 7525 recommendations on forward secrecy;
— the requirements concerning 112 bits of security strength have been changed to 128 bits of security strength;
— the requirements for the maximum certificate validity period have been changed from 3 years to 398 days;
— the requirements associated with the ECDSA signature certificate have been clarified;
— a requirement has been added for including the TLS 1.3 extension for pre-shared key (PSK) support.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html and www.iec.ch/national-committees.
