Crypto Stack use cases and examples

The Crypto Stack in AUTOSAR is a critical component that serves various use cases for securing data and communication within automotive systems. Some of the key use cases for the Crypto Stack in AUTOSAR include secure communication, data encryption, and digital signatures.

Data encryption

Let’s consider a scenario. In an AUTOSAR-based embedded application, SWC A needs to securely transmit sensitive data to SWC B over a Controller Area Network (CAN) bus. To ensure data confidentiality, SWC-A employs data encryption using the AUTOSAR Crypto Stack.

Here’s a list of the actors:

• SWC-A: The sender of sensitive data
• SWC-B: The recipient of the encrypted data
• AUTOSAR Crypto Stack: The cryptographic module responsible for data encryption and decryption
• Security Key Management: The component responsible for managing cryptographic keys

Here are the preconditions:

• SWC-A and SWC-B are configured and operational...
