DATA ERROR DETECTION TECHNIQUES
(a) Digital error detection techniques can be used to detect errors during the transmission or storage of data. An example of a digital error detection technique is the use of cyclic redundancy checks (CRCs). Coding techniques can be effective regardless of the transmission media (e.g. computer disks, modem communication, or internet).
(b) Transmission of data via electronic/digital means (e.g. file transfer protocol (FTP) sites, web downloads, or email) may be subject to malicious attack that can corrupt the integrity of data for its intended use. Provision of means to mitigate the intentional corruption of digitally transmitted data may already exist within the organisational construct and operating procedures of participating entities.
(c) The objective of data security is to ensure that data is received from a known source and that there is no intentional corruption during processing and exchange of data.
(d) Records should be maintained to show what data security provisions have been implemented.
(e) Provisions supporting this objective may include:
(1) implementation of technical data security measures to provide authentication and prevent intentional corruption during exchange of data (e.g. secure hashes, secure transmissions, digital signatures); and
(2) implementation of organisational data security measures to protect processing resources and prevent intentional corruption during processing of data.
EASA aviation regulations mandate robust aeronautical data quality management, emphasizing error detection and data security. Digital techniques like CRCs are crucial. Organizations must prevent data corruption during transmission and processing using technical measures (secure hashes) and organizational procedures, maintaining records of implemented security provisions.
