After two days of fierce competition at the District 17-5A Track and Field Championships at Barbers Hill’s Eagle Stadium, several local athletes will be moving on to the area meet on Wednesday. Barbers Hill finished first in the boys and girls team standings, while the Sterling boys group finished second. WebThe working is shown below: Input : 1.Plain text that has to be converted into ciphertext. 2.A KEY to encrypt the plain text. Output: Ciphertext. We have a simple formula for encryption. C = KPmod26. C is ciphertext, K is the key, P is the plain text vector. The KEY is generally given in the problem statement.

WebHill Ciphers Hill ciphers (invented in 1929) are a type of block cipher: the ciphertext character that replaces a particular plaintext character in the encryption will depend on the neighboring plaintext characters. The encryption is accomplished using matrix arithmetic. The encryption key for a Hill cipher is a square matrix of integers.
