Annotation of standard text IEC 62055-42-ed.1.0 :
IEC 62055-42:2022, specifies a token generation mechanism and token structure for smart prepayment functionality in markets where IEC 62055-41 compliant systems are not used, and where a different security mechanism is required by project-specific or national requirements. This document specifies token structure, authentication and an anti-replay mechanism, token operating model, and protocol. This document is informed by the STS Association key management services, and by the key management mechanisms used within the DLMS/COSEM security model within IEC 62056-6-2. Reference is made to the international STS token standards (IEC 62055-41, IEC 62055-51 and IEC 62055-52) for payment metering systems, and interworking has been considered where appropriate in terms of token carrier ranges in the decimal domain. IEC 62055-41 tokens and those described in this document are not interoperable, however their domains are designed to be mutually exclusive to ensure the two kinds of tokens do not interfere with each other. Metering application processing and functionality, HAN interface commands and attributes, WAN interface commands and attributes are outside the scope of this document; however, reference is made to other standards in this regard. The mechanism for auditing and retrieving data from the meter relating to tariffication, meter readings, profile data and other legal metrology information is outside the scope of this document; however, this is defined as part of any overall metering solution. Such interfaces for retrieving data from a meter may be defined using suitable protocols such as DLMS/COSEM as defined in the IEC 62056 series. IEC 62055-42:2022, specifie un mecanisme de generation de jetons ainsi que la structure de jetons associee a la fonctionnalite de prepaiement intelligent, destinee aux marches ou les systemes conformes a l’IEC 62055-41 ne sont pas utilises et lorsque les exigences nationales ou specifiques a un projet imposent l’utilisation d’un autre mecanisme de securite. Le present document specifie la structure des jetons, leur authentification, un mecanisme antirediffusion, le modele d’exploitation des jetons et le protocole associe. Le present document est informe par les services de gestion de cles de la STS Association ainsi que par les mecanismes de gestion de cles utilises dans le modele de securite DLMS/COSEM specifie dans l’IEC 62056-6-2. Une reference est faite aux normes internationales relatives aux jetons STS (IEC 62055-41, IEC 62055-51 et IEC 62055-52) pour les systemes de comptage a paiement, et l’interconnexion a ete envisagee le cas echeant en ce qui concerne les plages des supports de jetons dans le domaine decimal. Les jetons conformes a l’IEC 62055-41 et ceux decrits dans le present document ne sont pas interoperables, mais leurs domaines sont concus pour etre mutuellement exclusifs afin d’assurer que les deux types de jetons n’interferent pas l’un avec l’autre. Le traitement et la fonctionnalite des applications de comptage ainsi que les commandes et attributs des interfaces HAN et WAN ne relevent pas du domaine d’application du present document. Une reference est toutefois faite a d’autres normes traitant de ces aspects. Le mecanisme d’audit et de recuperation des donnees du compteur relatives a la tarification, des releves de compteurs, des donnees sur les profils et autres informations metrologiques legales ne releve pas du domaine d’application du present document. Il est cependant defini dans le cadre de toute solution de comptage globale. Il est permis de definir de telles interfaces pour la recuperation des donnees d’un compteur en utilisant des protocoles adaptes, tels que DLMS/COSEM defini dans la serie IEC 62056.
