Examples of the use of key management mechanisms are included in ISO Establish a izo secret key for a symmetric cryptographic technique between two entities A and B by key transport.
Make an entity’s public key available to other entities by key transport. Key management includes functions such isoo the generation, storage, distribution, deletion and archiving of keying material in accordance with a security policy ISO Life cycle A standard is reviewed every 5 years 00 Preliminary.
Final text received or FDIS registered for formal approval.
Establish a 117701 secret key for a symmetric cryptographic technique between two entities A and B by key agreement. As with other security services, key management can only be provided within the context of a defined security policy. Neither of them can predetermine the value of the shared secret key. In a secret key agreement mechanism, the secret key is the result of a data exchange between the two entities A and B. Monday to Friday – However, certain key distribution 117701- can depend on particular algorithm properties, for example, properties of asymmetric algorithms.
BS ISO/IEC – Information technology. Security techniques. Key management. Framework
In iwo public key transport mechanism, the public key of entity A must be transferred to other entities in an authenticated way, but not requiring secrecy. Check out our FAQs. Information technology — Security techniques — Key management– Part 3: All the frameworks, including this one, identify the basic concepts and characteristics of mechanisms covering different aspects of security.
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. The fundamental problem is to establish keying material whose origin, integrity, timeliness and in the case of secret keys confidentiality can be io to both direct and indirect users.
A 11770-1 key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists. 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.
It specifically addresses the use of asymmetric techniques to achieve the following goals.
However it does not specify details of protocol exchanges that might be needed. Therefore this version remains current.
