Information technology. Security techniques. Data integrity mechanism using a cryptographic check function employing a block cipher algorithm1 Scope This International Standard specifies a method of using a key and an n bit block cipher algorithm to calculate an m bit cryptographic check value. This method can be used as a data integrity mechanism to detect that data has not been altered in an unauthorised manner. The strength of the data integrity mechanism is dependent on the key length and its secrecy, on the nature of the cryptographic algorithm, and on m, the length of the check

To restrict the scales of density to the exclusion of relative density (formerly termed specific gravity)

The goal of DD IEC/TS 61850-80-1 is to describe standardized mapping of device-oriented data models (for example IEC 61850) with already defined attributes of CDC's and services (for example IEC 61850-7) onto the already defined ASDU's and services of IEC 60870-5-104 or IEC 60870-5-101
