The intronization is defined as an encryption method, i.e., inserting introns into an exon sequence to obtain ciphertext. Intronization can be used for information hiding, password salting, virus morphing, and an intermediate step of other encryption or hash primitives. Geometric objects can be applied to guide the intronization process. The existence of large number of introns in ciphertext could make frequency-based cryptanalysis difficult.
