Description of BS ISO 13492:2019 2019This document describes a data element related to key management which can be transmitted either in transaction messages to convey information about cryptographic keys used to secure the current transaction, or in cryptographic service messages to convey information about cryptographic keys to be used to secure future transactions. This document addresses the requirements for the use of the data element related to key management within ISOÂ 8583-1, using the following two ISOÂ 8583-1 data elements for DEA and TDEA:
The data element related to key management for DEA and TDEA is constructed from the concatenation of two ISO 8583-1 message elements, data element 53 — security related control information, and data element 96 — key management data. It conveys information about the associated transaction's cryptographic key(s) and is divided into subfields including a control field, a key-set identifier and additional optional information. For AES implementations, the data elements are summarized in one field. This document is applicable to either symmetric or asymmetric cipher systems.
