This part of ISO/IEC 18033 specifies block ciphers. A block cipher maps blocks of n bits to blocks of n bits, under the control of a key of k bits. A total of seven different block ciphers are defined. They are categorized in 98H96H96H96HTable 1.

This International Standard provides a privacy framework which

specifies a common privacy terminology;

defines the actors and their roles in processing personally identifiable information (PII);

describes privacy safeguarding considerations; and

provides references to known privacy principles for information technology.

This International Standard is applicable to natural persons and organizations involved in specifying, procuring, architecting, designing, developing, testing, maintaining, administering, and operating information and communication technology systems or services where privacy controls are required for the processing of PII.

ISO/IEC 11770-4:2017 defines key establishment mechanisms based on weak secrets, i.e. secrets that can be readily memorized by a human, and hence, secrets that will be chosen from a relatively small set of possibilities. It specifies cryptographic techniques specifically designed to establish one or more secret keys based on a weak secret derived from a memorized password, while preventing offline brute-force attacks associated with the weak secret. ISO/IEC 11770-4:2017 is not applicable to the following aspects of key management:
-      life-cycle management of weak secrets, strong secrets, and established secret keys;
-      mechanisms to store, archive, delete, destroy, etc. weak secrets, strong secrets, and established secret keys.

This document specifies mechanisms to establish shared symmetric keys between groups of entities. It defines symmetric key-based key establishment mechanisms for multiple entities with a key distribution centre (KDC), and defines symmetric key establishment mechanisms based on a general tree-based logical key structure with both individual rekeying and batched rekeying. It also defines key establishment mechanisms based on a key chain with group forward secrecy, group backward secrecy, or both group forward and backward secrecy.

This document also describes the required content of messages which carry keying material or are necessary to set up the conditions under which the keying material can be established. However, this document does not specify information that has no relation with key establishment mechanisms, nor does it specify other messages such as error messages. The explicit format of messages is not within the scope of this document.

This document does not specify the means to be used to establish the initial secret keys required to be shared between each entity and the KDC, nor key lifecycle management. This document also does not explicitly address the issue of interdomain key management.

Annex A lists the object identifiers assigned to the mechanisms specified in this document. For information purposes, a load balancing mechanism for a general tree structure is described in Annex B.
