The method of knowing the mapping between the
Rainbow Attack

Dictionary-type attack a brute force analysis
does not belong to
∉
when an object is not in a set
Belongs to
∈
when an object is within a set
subset
⊆
subset has fewer elements or equal to the set
A∪ B union (objects that belong to set A or set B)
| such that
A∩B Intersection: in both A and B
Used a polyalphabetic substitution cipher, which did
not repeat within a reasonable time period, along with
a secret key. For the cracking of the Enigma cipher,
Enigma Machine -Cypher
the challenge was thus to determine both the
10
algorithm used and the key. Enigma's main weakness,
though, was that none of the plain text letters could
be ciphered as itself.
Uses four 5 × 5 matrices arranged in a square, are
Four-square cipher9 where each matrix contains 25 letters for encoding
and decoding operations.
