Extention and cryptanalysis of golden cryptography by Sharabyan, Mohammad Tahghighi

“…Then a new extension to the original GC using discrete logarithm problem and hash function (GCHDLP) was proposed and the tests have shown that these versions of GC can resist the four basic attacks; the chosen plaintext attack, known-plaintext attack, the ciphertext-only attack, and chosen-ciphertext attack. …”

Cryptanalysis in cryptographic algorithm design by Z'aba, Muhammad Reza, Ahmad, Badrisham, Ibrahim, Subariah, Maarof, Mohd. Aizaini

“…Cryptography is a science of protecting information by changing it into unreadable format (encryption) called ciphertext using a key. The original message can be recovered from the ciphertext by means of decryption. …”
