Abstract: DNA computing is just a series of bio-operations on DNA strands by some specialenzymes. After the bio-operations on DNA strands and the Adleman's DNA algorithm for solving Directed Hamiltonian Path Problem were introduced, we discuss indetail the Boneh's method for attacking DES by DNA computing and point out the time cost can be reduced about a half by making use of a complementarity of DES algorithm. Finally, the possibility of attacking AES by a method similar to Boneh's is analyzed.

Key words: DNA, molecular computer, DES, AES
