Overview
ISO/IEC 10181-4:1997 is an international standard developed by ISO and IEC, providing a comprehensive framework for non-repudiation within Open Systems Interconnection (OSI) environments. Non-repudiation is a critical security service that ensures the generation and validation of irrefutable evidence concerning specific events or actions. This evidence helps resolve disputes about whether an action occurred, offering protection for both data and entities in open systems. The standard is designed for use in distributed computing, database systems, messaging services, and other domains where reliable evidence of transactions and communications is essential.
Key Topics
- Non-repudiation Services: The standard defines key services such as non-repudiation of origin and non-repudiation of delivery, aimed at preventing entities from denying participation in or receipt of communications.
- Trusted Third Parties (TTP): Describes different roles for TTPs, including evidence generation, time stamping, monitoring, key certification, signature generation, and evidence verification.
- Phases of Non-repudiation: Outlines the four main phases: evidence generation, evidence transfer, storage and retrieval, evidence verification, and dispute resolution.
- Types of Non-repudiation Evidence: Details elements such as digital signatures, data fingerprints, identifiers, time stamps, and notary information used as evidence.
- Policy and Management: Discusses the importance of non-repudiation policies, including rules for evidence generation, verification, storage, use, and adjudication. Management facilities also cover distribution and revocation of cryptographic keys.
- Security Mechanisms: Identifies mechanisms for delivering non-repudiation, such as digital signatures, secure envelopes, and use of TTPs. Emphasizes that the framework is algorithm-agnostic and supports both symmetric and asymmetric cryptographic techniques.
- Interactions with Other Security Services: Explains how non-repudiation interacts with related services like authentication, access control, confidentiality, integrity, and audit.
Applications
ISO/IEC 10181-4:1997 is widely applicable across various sectors requiring robust security frameworks, including:
- Secure Messaging: Underpins the integrity of messaging systems by providing assurance that messages are sent and received without denial.
- Database Operations: Ensures the accountability of add, modify, or delete operations by generating evidence for each transaction.
- Digital Transactions: Strengthens electronic commerce and contract signing by providing legally admissible evidence of actions.
- Distributed Applications: Supports open distributed processing environments, ensuring indisputable records of data transfers or system commands.
- Regulatory Compliance: Helps organizations meet legal or industry-specific requirements for non-repudiation in records management, financial transactions, and sensitive communications.
Related Standards
ISO/IEC 10181-4:1997 builds on and interacts with several other foundational standards:
- ISO/IEC 10181-1: Security frameworks for open systems - Overview
- ISO/IEC 7498-1 & 2: Basic Reference Model and Security Architecture
- ITU-T Recommendation X.800: Security architecture for OSI
