Ibn al-Durayhim

ʿAlī ibn Muḥammad Ibn al-Durayhim (Arabic: علي بن محمد ابن الدريهم‎; 1312–1359/62 CE) was an Arab[1] 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".[2]

His book entitled Clear Chapters Goals and Solving Ciphers (مقاصد الفصول المترجمة عن حل الترجمة) was recently discovered, but has yet to be published. It includes the use of the statistical techniques pioneered by Al-Kindi and Ibn 'Adlan.[3]
