Abstract: | Based on the characteristic of JAMBU,a forgery attack by using the principle,where the associated data can be transformed into the plaintext was proposed.It is shown that the attack requires a data complexity of about chosen plaintext,and a time complexity of about encryptions.Compared with the previous attack,this attack is more favorable. |
