Dr Mohammed Al-Suwaiyel, Professor at King Abdulaziz City for Science and Technology, KACST and former Minister of Telecommunications, is in Oxford on Thursday 26 April 2018 and is happy to give a short talk and answer questions on the Arab Origins of Cryptology. Cryptology, the art and science of making and breaking codes, has a history that is older than 4000 years. The first mention of cryptology in a formal sense started in the 9th century AD, by Arab Cryptologists. They designed new codes and systematically described cryptanalysis.

Mohammed is also very involved in outreach and implementation of the new Rhodes Scholarship, in partnership with Muhammad Alagil, for Saudi Arabia. If there is time available, we will use 20-30 minutes at the end of the meeting to brainstorm the outreach and implementation plans for the selecting in 2018 the first Rhodes Scholar from Saudi Arabia.
