Ibn al-Durayhim
From Infogalactic: the planetary knowledge core
ʻAlī ibn Muḥammad Ibn al-Durayhim (Arabic: ابن الدريهم; 1312–1359/62 CE) was an Arab cryptologist who gave detailed descriptions of eight cipher systems that discussed substitution ciphers, leading to the earliest suggestion of a "tableau" of the kind that two centuries later became known as the "Vigenère table".[1]
His book entitled Clear Chapters Goals and Solving Ciphers was recently discovered, but has yet to be published. It includes the use of the statistical techniques pioneered by Al-Kindi and Ibn 'Adlan.[2]
