Costs associated with the conversion/upgrade vary depending on the ATM vendor and age of the machine. In other cases, the machine will need to be replaced.
#Des encryption software
In many cases, upgrades in the software and keypads will make them compliant. The primary issue is migrating the thousands of legacy (old but in current use) ATM machines across the country to the new standard. Since April 2002, all new ATM installations were required to be 3DES capable. In addition, the ATM market is moving towards transacting business over the Internet, which brings its own set of risks.
The original data encryption standard (DES) that has been universally used since 1981 in the ATM market to encrypt personal identification numbers (PINs) is vulnerable to attack because of the exponential increase in computing power from personal computers. Eventually, all ATMs connected to the networks must be capable of handling the new encryption standard which uses 2 encryption keys, chosen independently at random, to encrypt a message multiple times. The new encryption standard, called Triple DES (3DES), was adopted by MasterCard and VISA to ensure the security of their networks. The purpose of this letter is to ensure credit unions are aware of the new minimum encryptions standards being required by the major ATM switch network vendors.
