BS ISO/IEC 11770-1:2010

Monday to Friday – Therefore this version remains current. Life cycle A standard is reviewed every 111770-1 years 00 Preliminary. As with other security services, key management can only be provided within the context of a defined security policy.

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.

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 is direct and indirect users. However, certain key distribution mechanisms can depend on particular algorithm properties, for example, properties of asymmetric algorithms.

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 transport.

All the frameworks, including this one, identify the basic concepts and 117700-1 of mechanisms covering different aspects of security. Key management includes functions such as the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO Final text received or FDIS registered for formal approval.

Neither of them can predetermine the value of the shared secret key. Proof sent to secretariat or FDIS ballot initiated: It specifically addresses the use of asymmetric techniques to achieve the following goals.

Examples of the use 117770-1 key management mechanisms are included in ISO Information technology — Security techniques — Key management– Part 3: Make an entity’s public key available to other entities by key transport. Check out our FAQs. 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.


Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key agreement. 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.

In a secret key agreement mechanism, the secret key is the result of a data exchange between the two entities A and B.
