BS ISO/IEC – Information technology. Security techniques. Key management. Framework
In ios 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 asymmetric techniques to achieve the following goals.
A private key can in all cases be distributed with these mechanisms where an existing, non-compromised key already exists. Make an entity’s public key available to other entities by key transport. Therefore this version remains current.
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.
BS ISO/IEC 11770-1:2010
However it does not specify details of protocol exchanges that might be needed. However, in practice the distribution of private keys is usually a manual process that relies on technological means like smart cards, etc.
Neither of them can predetermine sio value of the shared secret key. All the frameworks, including this one, identify the basic concepts and characteristics 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 The fundamental problem oso 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.
Proof sent to secretariat or FDIS ballot initiated: Check out our FAQs. Mechanisms using asymmetric techniques.
As with other security services, key management can only be provided within the context of a defined security policy. Monday to Friday – Life cycle A standard is reviewed every 5 years 00 Preliminary. 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. Final iao received or FDIS registered for formal approval.
Examples of the use of key management mechanisms are included in ISO However, certain key distribution mechanisms can depend on particular algorithm properties, for example, properties of asymmetric algorithms. Establish a shared secret key for a symmetric cryptographic technique between two entities A and B by key transport.
