This document provides an information report to the readers for the management of confidential data associated with hardware protected security environment (HPSE). The scope of the present document is common principles of confidential data, methodologies, conformance of SAE J3101 with regulations and standards, and use cases.

Abstract Supply chain management is key to industry efficiency, while information security and transparency are at the core of operations management. Blockchain technology shows great potential in this regard and can effectively make up for existing shortcomings. This article deeply explores the application of blockchain in new energy vehicle supply chain management, focusing on enhancing the systematization and collaboration of the supply chain through smart contract mechanisms. We established a collaborative contract model for the three-level supply chain. Especially from the perspective of the intermediate supply chain, we designed a smart contract mechanism to optimize key links such as order processing, payment, and logistics tracking, and used the alliance chain to ensure the safe sharing and sharing of information.

The emphasis of this document is on external Cybersecurity threats. Although many Cybersecurity threats can occur due to malicious activities by employees or flight Crew, the focus of this document is on addressing external Cybersecurity threats. ...This SAE Aerospace Information Report (AIR) provides information and exemplary guidance to understand and address Cybersecurity threats in IVHM-enabled systems. This AIR addresses specific vulnerabilities and considerations that are unique to IVHM-enabled systems. ...This AIR is not intended to cover the broader topic of Cybersecurity standards for aerospace systems, as there are specific SAE committees, such as G32, that are focused on addressing that scope.

To gain an understanding of the software Application Programming Interface (API) landscape for SAE J3101 [SAEJ3101] devices, the SAE Vehicle Electrical Hardware Security Task Force conducted an analysis of various automotive-relevant crypto APIs. The purpose of this analysis was to identify how well the existing APIs cover the SAE J3101 requirements and to highlight the areas of coverage within these APIs. By examining these APIs, the Task Force aimed to gain insights into the current state of API support for SAE J3101 devices and identify any gaps in coverage that need to be addressed.

The UN R155 regulation is the first automotive cybersecurity regulation and has made security a mandatory approval criterion for new vehicle types. ...These recommendations aim to enhance the comprehensiveness of the security assessment associated with UN R155, fostering a more uniform approach to evaluating cybersecurity in the context of vehicle type approvals.

., driver assistance functions, intrusion detection system, vehicle diagnostics, external device authentication during vehicle diagnostics, vehicle-to-grid and so on). The cybersecurity attacks targeting the global time result in false time, accuracy degradation, and denial of service as stated in IETF RFC 7384 [2].
