military encoding device

In the era of globalization, information and communication technology is developing very rapidly. The main priority in information and communication technology is how to secure it. This can be achieved with cryptography. The development of cryptography also triggered the development of cipher devices as the primary means of support. AN / ARC– 210 is one of the military cipher devices that has been used and continues to be updated.

Starting with the discovery of microprocessor technology in the 1960s, the application of cryptographic systems is no longer manual, or based on mechanical machinery, but turned to digital electronic applications. And cryptographic system algorithms have developed following the characteristics of digital electronic technology, which is based on binary operations “0” and “1”. And since then began the era of modern cryptography, which actually focuses more on the implementation of an electronic nature, by utilizing computer technology and high-speed data processing.

After seeing a glimpse of classical cryptography, then we will then enter the area of ​​contemporary cryptography, which has led to digital processing. Modern bit-based cryptographic algorithm. Each encryption operation is performed on data bits. Thus, all digital data can be encrypted using this cryptographic algorithm.

Modern cryptographic algorithms are divided into two main parts based on the keys used to do encryption and decryption. The two parts are the key asymmetry algorithm and the symmetry key algorithm.

 Technological developments are advances in developing microprocessors, field-programmable gate arrays (FPGAs), digital signal processors (DSPs), small-form-factor single-board computers, and other embedded computing technologies. Make wireless communication safer and faster. Small, fast, and power-efficient hybrid computing is currently the primary activation technology for modern cryptography that promises secure wireless computing capabilities for military forces, even to the front of the battle.

Encryption among the military is used in sending messages. Storing military and state confidential data in the storage media is always in an encrypted state.

Modern cryptographic equipment enables system designers to embed security in handheld devices such as small radios and smartphones to provide secure wireless communication on the battlefield. The United States military and security authorities are at the center of the largest and most important crypto modernization program in the past half century. Not only does sophisticated embedded computing open the way to wearable and handheld computing and wireless communications that are safe from enemy interception and eavesdropping, but it also makes the case for an approach that has never been used before modern cryptography to protect vital military computing and communications.

While previous generations of military cryptography mandated the use of secret algorithms and independent encryption hardware, encryption technology is now increasingly using special off-the-shelf (COTS) crypto algorithms and processing hardware is the most effective way to counter the effects of technological obsolescence, enabling operations network-centered military, addressing data dissemination and data sharing, making images and videos a major component of military intelligence and situational awareness, immediately utilizing new technology, keeping the cost of developing and maintaining cryptographic technology to a minimum, incorporating the latest cryptographic capabilities into security systems legacy, and ensuring interoperability between communications and computer systems of the United States and its secure allies.

National Security Agency (NSA) in Fort Meade, Md. Any military communication or computing system that uses security encryption is subject to NSA approval to ensure that the encryption is effective and implemented. In recent years, the NSA developed a military encryption algorithm, and maintained each algorithm as a tightly held secret. This secret crypto algorithm is designated as “Type 1” security.

The crypto Modernization Program is developing a fast, small crypto processor that saves size and weight for frontline combat strength. While the NSA still creates and manages type 1 classified – or what is now called “Suite A” – this update is the result of developments in existing technology. The NSA has in recent years begun to accept unclassified crypto algorithms created in private industry, as long as NSA experts can verify the effectiveness of these algorithms and authorize them for deployed military systems. The industrial non-classification crypto algorithm developed is most commonly known as the “Suite B” cryptography.

Department of Defense NSA and U.S. started the Cryptographic Modernization Program which continued in 2005 to solve problems in the crypto approach, including obsolescence, expensive maintenance costs, insufficient bandwidth, and integration of difficult systems and systems.
