The designed encryption algorithm has 32-bit input and 32-bit output and therefore cannot be used security purposes. Instead, it is designed for educational purposes. On the other hand, our study aims to teach basic concepts of a real cipher design and to make undergraduate students enthusiastic on the subjects like discrete mathematics, error correcting codes, computer architecture, coding theory, number theory and finite field theory. As a result, we do not only aim to give an introduction to real life security, but also aim to make undergraduate students more enthusiastic on the given subjects by giving illustrative examples for a modified and simplified version of the AES cipher. ©2010 IEEE.en10.1109/ITHET.2010.5480094info:eu-repo/semantics/closedAccessBlock Cipher; Cryptography; Educational Cipher; Symmetric EncryptionBasic Concepts; Block Cipher; Block Ciphers; Cipher Design; Coding Theory; Discrete Mathematics; Encryption Algorithms; Error Correcting Code; Finite Field Theory; Illustrative Examples; Symmetric Encryption; Undergraduate Students; Codes (Symbols); Computer Architecture; Computer Programming; Information Technology; Network Security; Number Theory; Students; CryptographyConference Object3283352-s2.0-77954415228N/A
