Abstract:According to the characteristics of mathematical formulae and chemical reaction equations, a chaos encryption scheme that is suitable for mathematical formulae and chemical reaction equations was proposed£®In the scheme£¬the mathematical language was translated into the language in the sense of theoretical computer science by the method used in TEX software£¬and then a mapping from a mathematical formula to a natural number sequence was bridged£® Further a chaos stream generator is designed to generate chaos keyª²streams to encrypt the corresponding number sequence£¬ and thus realize the encryption of mathematical and chemical formulae£®
