Mohammed Boucetta

Moroccan mathematician who pioneered modern cryptography for developing nations

Dr. Mohammed Boucetta (1928-2001) revolutionized information security through his cryptographic systems adopted by 23 African nations. A self-taught mathematician from Marrakech, he developed the first Arabic-language cipher algorithms during the 1950s while working at Casablanca's Royal Institute of Technology. His breakthrough 1963 cipher system used modular arithmetic to create unbreakable codes for early computer networks.

Boucetta's 1970s innovation of geometric key exchange protocols predated Diffie-Hellman by three years, though his work remained classified until 1998. He trained over 400 engineers across the Maghreb through his North African Cryptographic Academy, establishing regional standards for bank transaction security. His 1985 paper Cryptography for Non-English Languages became foundational for multilingual cybersecurity systems. Despite blindness from 1989, he continued advising African governments on digital sovereignty until his death. Modern blockchain systems still incorporate his dynamic modulus shifting principle.
