An Information Report on HPSE Management of Confidential Data
J3101-3
The scope of this Information Report is to address the current state of the art in managing confidential data in the technical and regulatory aspects. The report will provide guidance as enumerated below.
• Common Principles of data confidentiality must be outlined in one or more informative illustrative examples to provide the context of the role of an HPSE.
• J3101 Hardware support for technical aspects of secure management of confidential data
• J3101 Hardware support necessary for secure deletion/erase
• J3101 Hardware to achieve consistent secure management of the confidential data
• Achieve conformance with common principles in privacy regulations and standards
• Describe use cases for confidential data management
Rationale: A vehicle component could contain and use two main types of confidential data: secret elements such as keys; and data for applications. These data elements could be stored in the Hardware Protected Security Environment (HPSE) or outside of HPSE. While SAE J3101 provides guidance and requirements on key management in HPSE, providing more technical guidance on keys and data management could help stakeholders. Additionally, confidential data management could be based on OEM policy and government regulations.
