Abstract: Based on PCR and DNA sequencing technology, several attacks against a DNA steganography method are proposed and
discussed. Due to the limitation of finding complementary primes, electrophoretic technology and separation technology,
attacks above do not work. The attact by using possible words as primes is also discussed, and security enhancement methods
to prevent such attacks are proposed.

Key words: steganography, security, DNA
