On Efficiency of Distributed Password Recovery
One of the major challenges in digital forensics today is data encryption. Due to the leaked information about unlawful sniffing, many users decided to protect their data by encryption. In case of criminal activities, forensic experts are challenged how to decipher suspects’ data that are subject to investigation. A common method how to overcome password-based protection is a brute force passwo...
متن کاملClient-Server Password Recovery
Human memory is not perfect – people constantly memorize new facts and forget old ones. One example is forgetting a password, a common problem raised at IT help desks. We present several protocols that allow a user to automatically recover a password from a server using partial knowledge of the password. These protocols can be easily adapted to the personal entropy setting [7], where a user can...
متن کاملPractical Password Recovery on an MD5 Challenge and Response
This paper shows an attack against APOP protocol which is a challenge-and-response protocol. We utilize the Wang’s attack to make collisions in MD5, and apply it to APOP protocol. We confirmed that the first 3 octets of secret key can be recovered by several hundred queries under the man-in-the-middle environment.

متن کاملFast password recovery attack: application to APOP
In this paper, we propose a fast password recovery attack to APOP application in local which can recover a password with 11 characters in less than one minute, recover a password with 31 characters extremely fast, about 4 minutes, and for 43 characters in practical time. These attacks truly simulate the practical password recovery attacks launched by malware in real life, and further confirm th...
