SLIDE 2

Semiconductor Manufacturing Challenges

Challenges

Impact

Untrusted production environments
Overbuilding/overproduction
Reverse engineering/cloning/IP

Theft

Grey market chips/ knock offs
Limited production visibility
Costly audits
Lost revenue
Liability
Safety issues
ASP Erosion
Company / Product reputation
Additional support burden

Lack of Trust in Supply Chain

Multiple SKUs/single die increase production

and testing costs

Forecasting and production forecasting is

uncertain

Feature settings irreversible
Overbuild: inventory spoilage
Underbuild: missed market opportunities and

perishable demand

Complex and costly supply chain logistics
Costly inventory management

High Cost of Multiple SKUs

SLIDE 3

Requirements/solutions for better supply chain security

Secure device configuration
On-chip access control and rights management
Identity assurance and traceability
Attestation (what about anonymity?)
Certificates and revocation, TTPs, CRLs?
Secure distributed key management and KMS
Secure Personalization and key injection/on-board key gen
Chicken and egg problem?
Secure facilities; Tester security?
Multiple stage device lifecycle management
Secure Part #/inventory management
Secure Debug and RMA
Secure Audit/logs/data management
How does this
