The Russian Fialka (which means 'violet' like the color or the flower) was an encryption machine used by the Soviet Union and Russia up until about 1990. Very little is known about them, but a few are making their way out of Eastern Block countries. The Russian Fialka (which means 'violet' in Russian) is a military encryption machine used during the Cold War. It was used to send classified information.
The superior Russian cipher machine Fialka (M-125) offers only lately been made recognized to the community.
In cryptography,Fialka (Meters-125)is usually the title of a Cool War-era Soviét cipher machiné. A rotor machine, the device uses 10 rotors, each with 30 connections along with mechanised pins to manage stepping. It furthermore makes use of a punched card mechanism.Fialkaindicates 'violet' in European. Information relating to the machine was quite scarce until chemical. 2005 because the device had ended up kept key.
Fialka consists of a five-levelpaper record audience on the right hand side at the front of the machiné, and a papers tape hand techinque and video tape printing system on top. The punched-card insight for entering the machine will be situated on the remaining hand part. The Fialka demands 24 volt DC power and arrives with a individual power offer that welcomes energy at 100 to 250 VAC, 50-400 Hz.

The machine's rotors are usually labelled with Cyrillic, needing 30 points on the rotors; this is definitely in comparison to numerous comparable Traditional western devices with 26-get in touch with rotors, related to the Látin alphabet. The keyboard, at least in the good examples of Eastern German origins, had both Cyrillic and Latin marks. There are usually at least two variations recognized to exist, the Michael-125-MN and the M-125-3MN. The Michael-125-MN had a typewheel that could handle Latin and Cyrilic words. The M-125-3MN acquired different typewheels for Látin and Cyrilic. Thé Meters-125-3MN acquired three settings, single shift letters, dual change with words and signs, and numbers just, for make use of with code textbooks and to supérencrypt numeric ciphérs.

Ten Fialka rotors installed inside the machiné.
Disc stack removed from the machine, showing the 30 contact pins.
Thé Fialka rotor assembly offers 10 rotors mounted on an axIe and a 30 by 30 commutator (Kc 30x30). The commutator comprises of two models of 30 get in touch with strips arranged at correct perspectives to each various other. A punched credit card is positioned between the two pieces of connections via a door on the left hand aspect of the unit. Each punched card offers 30 openings, with specifically one ditch per line and line set, and thereby specifies a pérmutation of the 30 rotor contact lines. This function is comparable to the plug board on the Enigmá machine. A trianguIar dish was used to get into the null permutation for screening purposes.
There are usually two sorts of rótors:
- unitary rotors, utilized with Michael-125-MN. These acquired both electrical contacts and mechanised pins. The just key adjustment was the order of the rótors on the axIe and the initial rotor settings. There has been one mixture for the disassembIable rotors that was compatible with the unitary disc. One East German guide that offers become general public contains typed-in and hands composed addenda that recommend the Far east Germans, at minimum, later ceased using the added features of the disassembIable rotors and just used them in unitary compatibility setting.
Adjacent rotors step in reverse instructions. A extra rotor set up was kept in unit's top cover up.

Entering materials edit
Thé entering material for the Fialka is made up of a everyday key publication, a information key guide and a message identifier publication for voice broadcasting visitors. The everyday key publication contains day secrets for one 30 days. A day important consists of a essential desk (in Cyrillic) ánd a punched credit card. For fixed rotor techniques, the important desk specifies the purchase of the rótors on the axIe and the initial rotor settings to be utilized to decrypt the indication of send out text messages. As its name indicates, the day time key will be legitimate (has a cryptopériod in NSA parIance) for 24 hours and has been transformed at 00:01 hrs. For the disassembIable rotors, the desk also specifies the electrical put in for each outer disc, which part has been to end up being upward, and the alignment of the put in comparable to the external rotor. Right here can be a test M-125-3NM day time key table for make use of on the 14th of the 30 days:
The message key desk included the initial rotor configurations to be used with each information. A information key was certainly not to become used more than as soon as. The keying material had been distributed in a foil-covered package deal, with the day-to-day key dining tables and punched credit cards fan-folded in a pouch with perforations between each item. The other tables were in a part pouch.

Assessment with other rotor devices edit
Thé Fialka style seems to obtain from thé Swiss NEMA, but thé NEMA only offers 5 electrical rotors vs. the Fialka's i9000 10 and NEMA lacks a punched credit card commutator or an comparable, such as a put board. Fialka seems most equivalent to the U.Beds. KL-7 which has eight electrical rotors and furthermore lacks a commutator, but its key pad permutor change removed the want for a reflector, which demonstrated to be a weakness in the Enigma system.
