I think you all saw that Cardigan Chess Community has changed an owner. Sorry for not writing there, and I think, I should post some words here because they are related to computer programming. Now I am developing new cryptoalgorhytms, but they all are not safe. If algorytms used 56-bit key in 1990, now it is 192-bit. Why? Bit can be only at 2 values: 1 and 0. But if we create an algorythm, that uses trites (with analogy with bit - but it can be at 3 values: -1, 0, 1). So I need to create soft using trites instead of bits. I read some documentation, and there are no real computers using trites! All them use binary code! The last computer usint trites was "Setun-70" created in Soviet Union. So, I asked my friend, who is learning in MSU (Moscow State University) at programming courses, find some old documentation. He even took a photo of "Setun"! I read old documentations about logics in trites, and now I am coding an emulator, that emulates trinary OS. *** P.S There is only a processor of "Setun-70" on the photo!
