Abstract

Insecurity has been a major challenge the world over. In Africa for example, there are so many indigenous languages that can be easily exploited by insurgents to perpetrate evil. Hausa language is spoken by about 5% of Africa's population estimated to be 1.3Billion. In this paper, we carried out the statistical analysis of the alphabets of this language spoken mostly in the West Africa sub-region. The research estimated following: The probabilities of its 24 alphabets, The probabilities of two-letter words (digram) and the probabilities of three-letter words (trigrams) using a completed undergraduate Hausa language project containing 89,335 characters. The results obtain can be lever-aged upon by cryptanalysts to break ciphers (substitution or transposition) constructed in this language.
