WebThe Hill cipher is a linear transformation of a plaintext block into a cipher block. The above attack shows that this kind of transformation is easy to break if enough pairs of plaintexts and ciphertexts are known. Modern ciphers, in fact, always contain a non-linear component to prevent this kind of attacks. Menu Home Projects Teaching WebApr 12, 2015 · I have a task to write a programm which works with Hill cipher. And it was not hard to make it cipher my message, but I just can't make it uncipher it. If I use input data from here: http://en.wikipedia.org/wiki/Hill_cipher it gives the same result. But if I change a key - it won't be able to encipher the message.

WebTo encrypt a message, each block of n letters (considered as an n-component vector) is multiplied by an invertible n × n matrix, against modulus 26. To decrypt the message, each block is multiplied by the inverse of the matrix used for encryption. The matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible n … WebImplementation of Hill cipher in Java This program was written as an exercise of MSc in Computer Information Systems of Greek Open University, course PLS-62 Specialization in Networks and Communications.
