In a Substitution cipher, any character of plain text from the given fixed set of characters is substituted by some other character from the same set depending on a key. If one analytically knows the nature of the plain text, then the analyst can exploit the regularities of the language. In cryptography (field related to encryption-decryption) hill cipher is a polygraphic cipher based on linear algebra. They are substitution ciphers and one alphabets is substituted by a different alphabet. It is one of the simplest encryption technique in which each character in plain text is replaced by a character some fixed number of positions down to it.
