Blocknots

Blocknots were random sequences of numbers contained in a book and organized by numbered rows and columns and were used as additives in the recyphering of Soviet Union codes, during World War II. The Blocknot consisted of fifty sheets of 5-figure random additive, 100 additive groups to a sheet. No sheet was used more than once, thus the blocknots were in effect a form of one-time pad. The Soviet Unions highest grade ciphers that were used in the East, were the 5-figure codebook enciphered with the Blocknot book, and were generally considered unbreakable. (Wikipedia).
