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. Isoo the frameworks, including this one, identify the basic concepts and characteristics of mechanisms covering different aspects of security. However, in practice the distribution of private keys is usually a manual process that relies on technological means like smart cards, etc.
Make an entity’s public key available to other entities by key transport. Examples of the use of key management mechanisms are included in ISO Monday to Friday – Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement.
Key management includes functions such as the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO Therefore this version remains current.
Final text received or FDIS registered for formal approval.
However, certain key distribution mechanisms can depend on particular algorithm properties, for example, properties of asymmetric algorithms. Information technology — Security techniques — Key management– Part 3: However it does not specify details of protocol exchanges that might be needed.
The fundamental problem is to 1177-1 keying material whose origin, integrity, timeliness and in the case of secret keys confidentiality can be guaranteed to both direct and indirect users.

BS ISO/IEC – Information technology. Security techniques. Key management. Framework
In a public key transport mechanism, the public key of entity A must 1170-1 transferred to other entities in an authenticated way, but not requiring secrecy. Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key transport.
Neither of them can predetermine the value of the shared secret key. Mechanisms using asymmetric techniques.
In a secret key agreement mechanism, the secret key is the result of a data exchange between the iiso entities A and B. It specifically addresses the use of asymmetric techniques to achieve the following goals. Proof sent to secretariat or FDIS ballot initiated: Life cycle A standard is reviewed every 5 years 00 Preliminary.
In 117701- secret key transport mechanism, the secret key is chosen by one entity A and is transferred to another entity Bsuitably protected by asymmetric techniques.
