Signal Operating Instructions
Signal operating instructions (SOI) or Communications-Electronics Operation Instructions (CEOI) are U.S. military terms for a type of combat order issued for the technical control and coordination of communications within a command. They include current and up-to-date information covering radio call signs and frequencies, a telephone directory, code-words (for rudimentary encryption), and visual and sound signals. A designated battalion signal officer prepares the battalion SOI in conformance with the SOI of higher headquarters. During operations, SOI are changed daily. Since the fielding of the SINCGARS system, however, the paper SOI has generally faded from Army use. Electronic SOI are now generated, distributed and loaded along with cryptographic keys A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data.

Battalion
A battalion is a military unit, typically consisting of up to one thousand soldiers. A battalion is commanded by a lieutenant colonel and subdivided into several Company (military unit), companies, each typically commanded by a Major (rank), major or a Captain (armed forces), captain. The typical battalion is built from three operational companies, one weapons company and one headquarters company. In some countries, battalions are exclusively infantry, while in others battalions are unit-level organizations. The word ''battalion'' has its origins in the Late Latin word ''battalion'', which is derived from ''battalia'', meaning "battle" or "combat." The term was used to describe a large group of soldiers ready for battle. Over time, its meaning evolved in military terminology. The word "battalion" came into the English language in the 16th century from the French language, French , meaning "battle squadron" (similar to the Italian language, Italian meaning the same thing) and ...

SINCGARS
Single Channel Ground and Airborne Radio System (SINCGARS) is a VHF combat network radio (CNR) used by U.S. and allied military forces. In the CNR network, the SINCGARS’ primary role is voice transmission between surface and airborne command and control (C2) assets. The SINCGARS family replaced the Vietnam War-era synthesized single frequency radios ( AN/PRC-77 and AN/VRC-12), although it can work with them. The airborne AN/ARC-201 radio is phasing out the older tactical air-to-ground radios (AN/ARC-114 and AN/ARC-131). The SINCGARS is designed on a modular basis to achieve maximum commonality among various ground, maritime, and airborne configurations. A common receiver/transmitter (RT) is used in the ground configurations. The modular design also reduces the burden on the logistics system to provide repair parts. The SINCGARS can operate in either the single-channel (SC) or frequency hopping (FH) mode, and stores both SC frequencies and FH loadsets. The system is compa ...

Key (cryptography)
A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained. A key's security strength is dependent on its algorithm, the size of the key, the generation of the key, and the process of key exchange. Scope The key is what is used to encrypt data from plaintext to ciphertext. There are different methods for utilizing keys and encryption. Symmetric cryptography Symmetric cryptography refers to the practice of the same key being used for both encryption and decryption. Asymmetric cryptography Asymmetric cryptography has separate keys for encrypting and decrypting. These keys are known as the public and private keys, respectively. Purpose Since the key ...

Key Management
Key management refers to management of Key (cryptography), cryptographic keys in a cryptosystem. This includes dealing with the generation, exchange, storage, use, crypto-shredding (destruction) and replacement of keys. It includes cryptographic protocol design, Key server (cryptographic), key servers, user procedures, and other relevant protocols. Key management concerns keys at the user level, either between users or systems. This is in contrast to key scheduling, which typically refers to the internal handling of keys within the operation of a cipher. Successful key management is critical to the security of a cryptosystem. It is the more challenging side of cryptography in a sense that it involves aspects of social engineering such as system policy, user training, organizational and departmental interactions, and coordination between all of these elements, in contrast to pure mathematical practices that can be automated. Types of keys Cryptographic systems may use different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Radio Systems
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruction, pro ...
