Device Lifecycle Management (DLM) by INTEGRITY Security Services (ISS, A Green Hills Software company) is a key management infrastructure for medical devices. DLM allows manufacturers to manage digital trust assets and cryptographic operations across global supply chains. Backed by FIPS 140-2 Level 3 assurance, DLM securely generates, distributes, and injects keys, certificates, and sensitive data for zero exposure encryption of devices across untrusted manufacturing sites. With DLM, digital assets are protected until metered into each device, preventing compromise.
