Therefore this version remains current. Life cycle A standard is reviewed every 5 years 00 Preliminary. In a secret key agreement mechanism, the secret key is the result of a data exchange between the two entities A and B.

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

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. The fundamental problem is to establish keying material whose origin, integrity, 117770-1 and in the case of secret keys confidentiality can be guaranteed to both direct and indirect users.

However it does not specify details of protocol exchanges that might be needed.

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

Information technology — Security techniques — Key management– Part 3: As with other security services, key management can only be provided within the context of a defined security policy. Final text isoo or FDIS registered for formal approval.

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

BS ISO/IEC 11770-1:2010

Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement. Examples of the use of key management mechanisms are included in ISO Monday to Friday – Check out our FAQs.

Make an entity’s public key available to other entities by key transport. Isk private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists.

Proof sent to secretariat or FDIS ballot initiated: Mechanisms using asymmetric techniques.

However, in practice the distribution of private keys is usually a manual process that relies on technological means like smart cards, etc. Key management includes functions such as the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO However, certain key distribution mechanisms can depend on particular algorithm properties, for example, properties of asymmetric algorithms.

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