Apr 15, 2015 - Fialka M-125 (sometimes called the “Russian Enigma”) is an electro-mechanical rotor cipher machine used during the Cold War. The designers.
The innovative Russian cipher machine Fialka (Meters-125) offers only recently been produced identified to the public.
In cryptography,Fialka (Meters-125)is definitely the name of a Cool War-era Soviét cipher machiné. A disc machine, the gadget uses 10 rotors, each with 30 connections along with mechanical pins to manage stepping. It furthermore makes use of a punched card system.Fialkameans 'violet' in Russian. Information relating to the machine was quite scarce until m. 2005 because the device had been kept key.
Fialka contains a five-levelpaper recording audience on the right hand side at the top of the machiné, and a paper tape punch and cassette printing mechanism on best. The punched-card input for keying the machine is certainly situated on the remaining hand side. The Fialka needs 24 volt DC strength and arrives with a independent power offer that allows energy at 100 to 250 VAC, 50-400 Hz.
The machine't rotors are usually branded with Cyrillic, requiring 30 points on the rotors; this is usually in comparison to numerous comparable Traditional western devices with 26-contact rotors, matching to the Látin alphabet. The key pad, at minimum in the examples of Eastern German origin, got both Cyrillic and Latin marks. There are at least two versions recognized to can be found, the Michael-125-MN and the Meters-125-3MN. The Meters-125-MN acquired a typewheel that could manage Latin and Cyrilic letters. The M-125-3MN acquired split typewheels for Látin and Cyrilic. Thé M-125-3MN experienced three modes, single shift letters, dual change with characters and signs, and digits just, for make use of with program code textbooks and to supérencrypt numeric ciphérs.

Thé Fialka disc assembly has 10 rotors mounted on an axIe and a 30 by 30 commutator (Kc 30x30). The commutator comprises of two sets of 30 get in touch with strips fixed at right sides to each various other. A punched cards is placed between the two pieces of contacts via a door on the left hand side of the device. Each punched cards has 30 holes, with specifically one opening per row and line pair, and thus specifies a pérmutation of the 30 disc contact lines. This function is equivalent to the plug plank on the Enigmá machine. A trianguIar dish was used to get into the null permutation for assessment purposes.
There are usually two forms of rótors:
- unitary rotors, utilized with Meters-125-MN. These experienced both electric connections and mechanised pins. The only key adjustment had been the purchase of the rótors on the axIe and the initial rotor settings. There has been one mixture for the disassembIable rotors that had been compatible with the unitary disc. One Eastern German manual that provides become public contains typed-in and hands created addenda that recommend the East Germans, at least, later ceased making use of the added features of the disassembIable rotors and only used them in unitary compatibility setting.

Entering materials edit
Thé keying materials for the Fialka consists of a everyday key guide, a message key book and a message identifier book for put out visitors. The day-to-day key publication contains day time tips for one month. A time crucial consists of a essential table (in Cyrillic) ánd a punched credit card. For set rotor systems, the essential desk specifies the order of the rótors on the axIe and the preliminary rotor settings to become used to decrypt the sign of transmitted messages. As its name implies, the day key can be valid (provides a cryptopériod in NSA parIance) for 24 hrs and was changed at 00:01 hours. For the disassembIable rotors, the desk also specifies the electric place for each external disc, which part had been to be up, and the positioning of the put in relatives to the external rotor. Right here can be a small sample Meters-125-3NM day key desk for use on the 14tl of the 30 days:
The information key desk included the preliminary rotor settings to become used with each message. A message key had been certainly not to end up being used more than as soon as. The entering material had been dispersed in a foil-covered package deal, with the daily key furniture and punched cards fan-folded in a pouch with perforations between each product. The various other tables were in a aspect sack.
Evaluation with some other rotor machines edit
Thé Fialka design appears to obtain from thé Swiss NEMA, but thé NEMA only offers 5 electrical rotors vs. the Fialka's i9000 10 and NEMA does not have a punched card commutator or an equal, such as a plug table. Fialka appears most similar to the U.S i9000. KL-7 which provides eight electric rotors and also does not have a commutator, but its key pad permutor change eliminated the want for a reflector, which proved to end up being a a weakness in the Enigma system.
