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

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

work for Secure Enclaves?
