Key management includes functions such as the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO Make an entity’s public key available to other entities 117701- key transport. Mechanisms using asymmetric techniques.

All the frameworks, including this one, identify the basic concepts and characteristics of mechanisms covering different aspects of security. Life cycle A standard is reviewed every 5 years 00 Preliminary.

Therefore this version remains current. Proof sent to secretariat or FDIS ballot initiated: Monday to Friday – In a secret key agreement mechanism, the secret key is the result of a data exchange between the two entities A and B. However, certain key distribution mechanisms can depend on particular algorithm properties, for example, properties of asymmetric algorithms.


However it does not specify details of protocol exchanges that might be needed. Final text received or FDIS registered for formal approval. The fundamental problem is to establish keying material whose origin, integrity, timeliness and in the case of secret keys confidentiality can be guaranteed to both direct and indirect users.

Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key transport.

BS ISO/IEC – Information technology. Security techniques. Key management. Framework

Examples of the use of key management mechanisms are included in ISO It specifically addresses the use of asymmetric techniques to achieve the following goals.

Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement.

Check out our FAQs. In a secret key transport mechanism, the secret key is chosen by one entity A and is transferred to another entity Bsuitably protected by asymmetric techniques. As with other security services, key management can only be provided within the context of a defined security policy.

A private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists. In a public key transport mechanism, the public key of entity A must be transferred to other entities in an authenticated way, but not requiring secrecy. Neither of them can predetermine 111770-1 value of the shared secret key.

Information technology — Security techniques — Key management– Part 3: However, in practice the distribution of private keys is 117701 a manual process that relies on technological means like smart cards, etc.
