Monday to Friday – As with other security services, key management can only be provided within the context of a defined security policy. However, in practice the distribution of private keys is usually a manual process that relies on isk means like smart cards, etc.

It specifically addresses the use of asymmetric techniques to achieve the following goals.

Check out our FAQs. Examples of the use of key management mechanisms are included in ISO In a secret key agreement mechanism, the secret key is the result of a data exchange between the two entities A and B.


Information technology — Security techniques — Key management– Part 3: Final text received or FDIS registered for formal approval. 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 by key transport.

Proof sent to secretariat or FDIS ballot initiated: Life cycle A standard is reviewed every 5 years 00 Preliminary. A private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists. Therefore this version remains current. In a public key transport mechanism, the public key of entity A must be transferred to other entities in 117700-1 authenticated way, but not requiring secrecy.

However it does not specify details of protocol exchanges that might be needed. Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key transport.


117700-1 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. Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement. Neither of them can predetermine the value of the shared secret key.

All the frameworks, including this one, identify the basic concepts and characteristics of mechanisms covering different aspects of security.

Mechanisms using asymmetric techniques. However, certain key distribution mechanisms can depend on particular algorithm properties, for example, properties of asymmetric algorithms.

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.
