Hill Cipher SecurityThe basic Hill Cipher is vulnerable to a known-plaintext attack that attacks by key because it is completely linear algebra. An opposite site that intercepts n plaintext/ciphertext character pairs can set up a linear system that can be easily solved; if this will happen ...
If we use the Hill cipher withm,26English letters and10decimal digits to encrypt plaintext "Engineer2"by using the key matrix [128856935] then the obtained cipher text is.(Note thatZ=25,0=26,1=27,2=28...Hint: Use modula...
