| Abstract: | A detailed analysis of several formal attack models such as indistinguishability under chosen-plaintext attack,indistinguishability under chosen-ciphertext attack and indistinguishability under adaptive chosen-ciphertext attack was discussed in this paper.The application using such attack models was compared with each other,which provided a theory basis to design and analyse the cryptographic protocols using provable security theory. |
