Check out our FAQs. However, certain key distribution mechanisms can depend on particular algorithm properties, for example, properties of asymmetric algorithms. Examples of the use of key management mechanisms are included in ISO Therefore this version remains current. 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. Key management includes functions such as the generation, 17170-1, distribution, deletion and archiving of keying material in accordance with a security policy ISO Final text received or Io registered for formal approval.


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

However it does not specify details of protocol exchanges that might be needed. Information technology — Security techniques — Key management– Part 3: Neither of them can predetermine the value of the shared secret key.

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 not requiring secrecy. A private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists.

Mechanisms using asymmetric techniques. Life cycle A standard is reviewed every 5 years 00 Preliminary.

Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement. Make an entity’s public key available to other entities by key transport.

Monday to Friday – Proof sent to secretariat or FDIS ballot initiated: However, in practice the distribution of private keys is usually a manual process that relies on technological means like smart cards, etc.


In a secret key transport mechanism, the secret key is chosen by one entity A and is transferred to another entity Bsuitably protected io asymmetric techniques.

In a secret key agreement mechanism, the secret key is the result of a data exchange between the two entities A and B. It specifically addresses the use of io techniques to achieve the following goals. Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key transport. All the frameworks, including this one, identify the basic concepts and characteristics of mechanisms sio different aspects of security.
