Citát dňa - Oficiálne dejiny Úradu pre bezpečnosť ministerstva zahraničia USA

Tu je odkaz na ‘History of the Bureau of Diplomatic Security of the United States Department of State - Dejiny Úradu diplomatickej bezpečnosti Ministerstva zahraničia USA’. Táto kniha popisuje dejiny Úradu diplomatickej bezpečnosti - (Bureau of Diplomatic Security) a jeho predchodcov – Úrad bezpečnosti a Úrad hlavného špeciálneho agenta (Office of the Chief Special Agent) amerického ministerstva zahraničných vecí – od jeho objavenia v r. 1916 až do súčasnosti.
Kapitola č. 2 sa zaoberá vývojom počas II. svetovej vojny a hlavnou snahou o zlepšenie bezpečnosti na zahraničných zastupiteľstvách. Bezpečnosť na väčšine ambasád bola žalostná, najmä v Moskve.
Nanešťastie je tu len letmá zmienka o kódoch Ministerstva zahraničia USA - Gray, Brown a prúžkovej šifry M-138 keďže kniha sa zväčša zaoberá všeobecnými bezpečnostnými opatreniami.

Crypto chip / The Codestar module add-on board

Obraz
The CodeStar module was designed for encryption and decryption of information for personal computers. The board was inserted into a free computer slot and occupied one 8-bit bus slot of a PC, XT, AT class computer. The module was supplied with a floppy disk with files in the Turbo C++ language under the MS-DOS OS . The original CRY 8 customer circuit, based on reliable technology had the entire information encryption and decryption algorithm hidden. This algorithm ( Feistel -type algorithm) was developed and manufactured in Switzerland for reliability on a special order basis, together with a semi-custom integrated circuit using CMOS VLSI technology. The order was placed by the Institute of Computer Systems of the Slovak Academy of Sciences (today‘s Institute of Informatics SAV ). The module was used to encrypt and decrypt the user's information or the user's entire file with an original and constantly changing key, it served to protect the user's data from unauthor...
