"Well, then, thank you," he sneered. "But, now, I am back. I will appreciate no further procedural interference." He sat up brusquely indicating that his was the last word on the subject. Unaware of the political sidebar in progress, Hammacher contin- ued. "Ciphers were evolved over the centuries until they reached a temporary plateau during World War II. The Germans used the most sophisticated message encoding or encryption device ever devised. Suitably called the Enigma, their encryption scheme was nearly uncrackable until the Allies captured one of the devices, and then under the leadership of Alan Turing, a method was found to regularly decipher intercepted German High Command orders. Many historians consider this effort as being instrumental in bringing about an end to the war. "In the years immediately following World War II, the only per- ceived need for secrecy was by the military and the emerging intelligence services, namely the OSS as it became the modern CIA, the British MI-5 and MI-6 and of course our opponents on the other side. In an effort to maintain a technological leadership position, the National Security Agency funded various projects to develop encryption schemes that would adequately protect govern- ment information and communications for the foreseeable future. "The first such requests were issued in 1972 but it wasn't until 1974 that the National Bureau of Standards accepted an IBM pro- posal for an encryption process known as Lucifer. With the assistance of the NSA who is responsible for cryptography, the Data Encryption Standard was approved in November of 1976. There was an accompanying furor over the DES, some saying that the NSA intentionally weakened it to insure that they could still decrypt any messages using the approved algorithm. "In 1982 a financial group, FIMAS endorsed a DES based method to authenticate Electronic Funds Transfer, or EFT. Banks move upwards of a trillion dollars daily, and in an effort to insure that all monies are moved accurately and to their intended desti- nations, the technique of Message Authentication Coding was introduced. For still unknown reasons it was decided that en- crypting the contents of the messages, or transfers, was unneces- sary. Thus, financial transactions are still carried out with no protection from eavesdropping." "Excuse me, Mr. Hammacher, I want to understand this," interrupt- ed Senator Deere. "Are you saying that, since 1976, we have had the ability to camouflage the nation's financial networks, yet as of today, they are still unprotected?" Rickfield looked over at Nancy in disgust but the single camera missed it. "Yes, ma'am, that's exactly the case," replied Hammacher. "What does that mean to us? The Government? Or the average citi- zen?"
