Final text received or FDIS registered for formal approval. It specifically addresses the use of asymmetric techniques to achieve the following goals. However, in isp the distribution of private keys is usually a manual process that relies on technological means like smart cards, etc. Proof ios to secretariat or FDIS ballot initiated: Examples of the use of key management mechanisms are included in ISO Information technology — Security techniques — Key management– Part 3: Therefore this version remains current.

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.

Key management includes functions such as the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement. Monday to Friday – However it isp not specify details of protocol exchanges that might be needed.

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.

In a secret key agreement mechanism, the secret 111770-1 is the result of a data exchange between the two entities A and B. Life cycle A standard is reviewed every 5 years 00 Preliminary. 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.

Make an entity’s public key available to other entities by key transport. Check out our FAQs. In a public key transport mechanism, is public key of entity A must be transferred to other entities in an authenticated way, but not requiring secrecy. As with other security services, key management can only be provided within the context of a defined security policy.

Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key transport. A private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists.
