Bootloader

-

 The boot manager and bootloader are SW components that reside in two permanent partitions of the ECU’s flash memory.

Purpose of boot manager:

  • Establish the ECU entry point upon power up or power on reset
  • Request Security Peripheral to authenticate bootloader SW and application SW prior to their executions
  • Support secure boot Strategy.
The main purpose of the bootloader is to enable the flash programing of application SW and Calibration data. 

The boot manager or bootloader implements the startup sequence when the ECU is powered up or after power on reset. The startup sequence refers to the initial set of operations that is responsible for initializing the ECU and for determining the ECU programming state and whether control shall remain in boot or be transferred to the application software.

Overview of ISO/SAE 21434 Standard

-
Image
ISO/SAE 21434, jointly published by the International Standardization Organization (ISO) and the Society of Automotive Engineers (SAE), serves as a comprehensive cybersecurity framework for electronic systems within road vehicles. Developed to bolster cybersecurity across the entire lifecycle of automotive products, this standard outlines essential vocabulary, objectives, requirements, and guidelines. Purpose and Scope: The primary objective of ISO/SAE 21434 is to enhance cybersecurity measures for vehicles throughout their lifecycle. By providing a standardized framework, this standard facilitates the establishment of cybersecurity policies, risk management practices, and a cybersecurity-oriented culture within organizations operating in the automotive industry. Three Pillars: ISO/SAE 21434 is structured around three main pillars: Cyber Security Governance:   Establishing policies, processes, and cultural norms to govern cybersecurity activities within organizations. Risk Man...

Cryptography and Encryption Basics I What is encryption Encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized can't.  Converts information from plain text into encrypted ciphertext. But how...? Encryption used algorithm! An algorithm is a procedure that the encryption process follows. The specific algorithm is called the ciper or code. there are many types so encryption algorithms. The encryption's goal and level of security determine the most effective solution. Triple DES, RSA and Blowfish are some examples of encryption algorithms or Ciphers. What is Decryption? Decryption is the process of taking encoded or encrypted text or other data and converting it back into text that you or the computer can read and understand.  converts information from encrypted ciphertext into plain text  Basic Example  Private key vs Public Key Private Key (symmetric key): This means that ...

 1. BCM (Body Control Module)    - Function: The BCM is responsible for controlling various electronic systems within the vehicle's body. This includes functions like interior lighting, power windows, door locks, windshield wipers, and other comfort and convenience features.    - Importance: It acts as a central hub for various sensors and inputs, ensuring that the vehicle’s body-related electronics operate smoothly.  2. Gateway ECU    - Function: The Gateway ECU acts as a communication hub between different networked ECUs in the vehicle. It ensures that data is correctly routed between systems like powertrain, infotainment, and body control.    - Importance: Vital for ensuring seamless communication between various subsystems in modern vehicles.  3. ETM (Electric Traction Motor)    - Function: Manages the electric traction motor, which provides propulsion in electric or hybrid vehicles. It controls the motor's speed, torq...
