ISO/IEC 11770-1:2010 PDF

Overview

ISO/IEC 11770-1:2010 - Information technology - Security techniques - Key management - Part 1: Framework - defines a vendor‑ and algorithm‑neutral key management framework. It establishes a general model and terminology for managing cryptographic keying material across its life cycle, covering both automated and manual aspects (but not low‑level protocol exchanges). The standard is intended as the foundational reference for subsequent parts of ISO/IEC 11770 and for designers of secure systems and key management services.

Key topics and technical requirements

• General model and terminology: definitions for keys, keying material, key agreement, key transport, certification authority, and related concepts.
• Key life cycle model: states and transitions (generation, registration, distribution, installation, storage, archiving, revocation, deregistration, destruction).
• Key management services: standardized service concepts including Generate‑Key, Register‑Key, Create‑Key‑Certificate, Distribute‑Key, Install‑Key, Store‑Key, Derive‑Key, Archive‑Key, Revoke‑Key, Deregister‑Key, Destroy‑Key.
• Protection mechanisms: guidelines for protecting keys by cryptographic, non‑cryptographic, physical and organisational means.
• Conceptual key distribution models: distribution between two entities, within a domain, and between domains; includes roles such as key distribution centre and key translation centre.
• Support services: key management facility and user‑oriented support functions.
• Threats and information objects: informative annexes cover typical threats to key management and key management data elements.
• Scope constraints: focuses on architecture and services; does not mandate specific cryptographic algorithms or protocol message formats.

Applications and who uses it

ISO/IEC 11770-1:2010 is used by:

• Security architects and system designers building Key Management Systems (KMS), Public Key Infrastructures (PKI), HSM integrations and cloud key management.
• Product developers of secure devices (smart cards, TPMs, HSMs) and software implementing key lifecycle controls.
• Enterprise security teams and DevOps designing key rotation, storage and distribution policies for cloud, IoT and messaging systems.
• Compliance officers and auditors mapping organizational security policy to standard key management practices. Practical applications include secure key generation, certificate lifecycle planning, cross‑domain key exchange models, and establishing organizational controls for key storage, archival and secure destruction.

Related standards

• ISO/IEC 11770 series - Part 2 (symmetric mechanisms), Part 3 (asymmetric mechanisms), Part 4 (weak secrets), Part 5 (group key management - under preparation).
• ISO/IEC 10181 (security frameworks for open systems), ISO 11568 (examples of key management mechanisms), ISO/IEC 13888 (non‑repudiation for key management), ISO 7498‑2 (security policy context).
