CLC/TC 47X NWIP - WI 80924 prEN 50XXX Cybersecurity requirements for tamper-resistant microprocessors and microcontrollers

Scope

This standard will define the technical specifications allowing the demonstration of compliance with the CRA Essential Requirements by tamper-resistant MCUs/MPUs expected to be resistant to Enhanced Basic potential of attack (currently defined by JIL, potentially adapted to the upcoming definition for the CRA, for instance from the “Cybersecurity requirements for products with digital elements” series of standards). To cover such topics, the current standard will refer as much as possible to existing standards/specifications when relevant and will only define and include additional content where gaps are identified.

Purpose

On April 16th 2024 the European Commission published a draft standardisation request to European Standards Organisations in support of Union policy on cybersecurity requirements for products with digital elements. The request is part of the preparatory measures in view of the adoption of the legislative proposal COM/2022/454 (Proposal for a REGULATION OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on horizontal cybersecurity requirements for products with digital elements and amending Regulation (EU) 2019/1020). The Standardisation request requests a series of 15 horizontal standards (1-15) to provide a coherent generic framework, methodology and taxonomy that can be used to develop further product-specific standards according to market needs and a set of 26 vertical standards (16-41) for important or critical categories of products in the Cyber Resilience Act, covering a specific set of risks appropriate to a given intended purpose and foreseeable use. The purpose of this standard is to answer the items #37 (European standard(s) on essential cybersecurity requirements for tamperresistant microprocessors) and #38 (European standard(s) on essential cybersecurity requirements for tamper-resistant microcontrollers) of the Standardization request described above. This standard shall be consistent with the Cyber Resilience Act and where applicable with other European and harmonised standards developed or under development in the various relevant sectors. The TC47X WG2 has been created to cover such activity in preparation of its assignment to CENELEC by the European Commission
