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

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. Make an entity’s public key available to other entities by key transport.

However, in practice the distribution of private keys is 111770-1 a manual process that relies on technological means like smart cards, etc. Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key transport. Examples of the use of key management mechanisms are included in ISO As with other security services, key management can only be provided within the context of 11770-11 defined security policy.

Check out our FAQs. Therefore this version remains current. Key management includes functions such as the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO 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. A private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists.

Life cycle A standard is reviewed every 5 years 00 Preliminary.

Final text received or FDIS registered for formal approval. Neither of them can predetermine the value of the shared secret key. Information technology — Security techniques — Key management– Part 3: Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement.

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

In a secret key 1170-1 mechanism, the secret key is the result of a data exchange between the two entities A and B. Proof sent to secretariat or FDIS ballot initiated: It specifically addresses the use of asymmetric techniques to achieve the following goals. All the frameworks, including this one, identify the basic concepts and characteristics of mechanisms covering different aspects of security.
