A cipher alphabet is a one to one mapping to a plain text alphabet. An example of such mapping is given below: Plain Alphabet: a b c d e f g h i j k l m n o p q r s t ...

Abstract: This research article presents a modified Hill Cipher algorithm that incorporates a novel alphanumeric encoding scheme, for the extended character set that includes alphabets, digits, and ...

Abstract: The article proposes a new quantum-resistant cryptographic algorithm constructed based on the OTP (One-Time Pad) cipher and a hash function. By inheriting the property of “perfect secrecy” ...
