The purpose of this study is to develop a contents when we are going to introduce cryptography and information security for vocational high school students. For this we do a survey of the students' level for understanding of information security and the 7th curriculum for school mathematics, 2007 revised curriculum for school mathematics, the curriculum for vocational high school, and we search for the material that connects between mathematics subjects and vocational subjects. We develop a text book that introduces information security and cryptography. After we teach vocational high school students by using this developed book, we get the result that learning cryptography with computer programming makes a good motivation of learning mathematics and roles a parameter between mathematics curriculum and vocational curriculum. As a result we propose that the developed contents can be used in 'Practical Mathematics' in the 7th curriculum for school mathematics or 'Application of Mathematics' in 2007 revised curriculum for school mathematics.

The number of college-oriented students in vocational high schools is increasing every year. For this reason, it is necessary to revise the curriculum of vocational schools, so that it is properly connected to college level education. In this paper, we try to find problems in computer curriculum by analyzing computer related courses currently taught by information computer departments in commerce information high schools. Based on the findings, we propose a desirable computer curriculum for commercial information high schools. We include the contents of each course, and suggest the way to administer the proposed curriculum in three year course of study.
