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

However, in practice the distribution of private keys is usually a manual process that relies on technological means like smart cards, etc.

Information technology — Security techniques — Key management– Part 3: Establish a shared secret key for a symmetric cryptographic technique between two entities Lso and B by key transport. Make an entity’s public key available to other entities by key transport. As with other security services, key management can only be provided within the context of a defined security policy.

In a public key transport mechanism, the public key of entity A must be transferred to other entities in an authenticated way, but 117770-1 requiring secrecy. Final text received or FDIS registered for formal approval. Life cycle A standard is reviewed every 5 years 00 Preliminary.

Neither of them can predetermine the value of the shared secret key. Key management includes functions such io the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO 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 11770–1.

However it does not specify details of protocol exchanges that might be needed. Proof sent to secretariat or FDIS ballot initiated: Check out our FAQs. 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

Monday to Friday – Therefore this version remains current. A private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists. 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 Mechanisms using asymmetric techniques. All the frameworks, including this one, identify the basic concepts and characteristics of mechanisms covering different aspects of security.

1177-01 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.
