GENERAL

More explanation and guidance on data security, including data error detection and authentication, may be found in Section 2 of EUROCAE ED-76A.

DATA ERROR DETECTION

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).
