Securing the future
of Automotive
Automotive Update
• With the rapidly increasing
amount of designs using Ethernet
for communication in cars, the
need for security is increasing
• Compared to the first generation
of Ethernet in cars, the upcoming
architectures have much more
complex use cases
• Ethernet is now entering ADAS
domains in the car where the
need for safe and secure
communication is paramount
2
More than a standard switch
is required to address these
needs:
Marvell’s Secure Automotive
Ethernet Switch SoC
Areas to Secure
3
Software Configuration
Runtime
configuration
access
Diagnostic
access
Configuration
or firmware
update
Data
exchange
Intrusion
detection/
prevention
Secure – Software Boot
4
Requirements:
Ensure authenticity and integrity of
any software running on the device
Solution:
Trusted Boot concept:
• Uses asymmetric cryptography
• Root of trust / trust anchor
• Chain of trust
• Only public key is needed locally
• OEM has the private key to sign
Secure – Update
5
Requirements:
Ensure authenticity and integrity of
any software and/or configuration
update before using it, and
Ensure that any failure during the
update process still results in a
bootable and trusted firmware and
configuration (fail-safe)
Solution:
Trusted Update concept:
• Use the measures from Trusted Boot
and Trusted Configuration for every
update block before activation it
• Use backup images to ensure fail-
safe operation
Secure – Runtime Access
Requirements:
Ensure that only authenticated entities
can access the device for Diagnostic,
Configuration and Update
Solution:
Trusted Runtime Access concept:
• Authenticate any and all access to
the device
• Protect and shut down any
attempted unauthorized access
6
Intrusion Prevention/Intrusion Detection
7
Requirements:
Detect Intruders and Prevent
Intrusions
Solution:
Intrusion-safe concept:
• Combine hardware pre-filtering
with TCAM and ingress rate limiting
with a Deep Packet Inspection (DPI)
module to monitor data flow and
detect anomalies
• Log/report anomalies
• Execute counter measures
SUMMARY
Marvell provides you
with the industry’s first
secure automotive
gigabit ethernet switch,
enabling a new level of
safe and robust data
transmission in next-
generation connected
vehicles
