Securing SPI (Serial Peripheral Interface) Data for Field Replaceable Units (FRUs) in Commercial Electronic Devices

Roopak Ingole ^[4] | Siva Sathyanarayana Movva ^[3]

Abstract: This paper will delve into the significance of secure communication within commercial embedded systems, focusing on the role of Field Replaceable Units (FRUs), the Serial Peripheral Interface (SPI) and non-volatile storage. It will set the stage for the necessity of securing SPI data to prevent unauthorized access and ensure reliable and confidential communication, especially in critical applications such as public safety, military, and industrial settings. The paper's objectives, including identifying vulnerabilities, exploring security challenges, and proposing robust security strategies, will be outlined. It will introduce the concept of Field Replaceable Units (FRUs) and their significance in maintaining and upgrading electronic systems. Furthermore, it will discuss the Serial Peripheral Interface (SPI) protocol's role in enabling communication between the microcontroller and other peripherals in FRUs along with non-volatile storage on FRU, setting the stage for a discussion on the security implications of SPI data transmission and storage.

Keywords: SPI, Serial Peripheral Interface, Field Replaceable Unit, FRU
