The security requirements of this study are confidentiality, integrity, anonymity, efficiency, poison attack resistance and dictionary attack
But like all the other security techniques, this technique also has security threats like shoulder surfing, dictionary attack
, social engineering etc.
Thus, the adversary is able to launch an offline dictionary attack
In the dictionary attack
procedure, the password cracker first reads the salt from locksettings.db file only if the PIN is used by the victim (in line (7)).
Similar to Tip 1, this prevents a dictionary attack
and is difficult to physically pass around compared to a phrase (i.e.
Only if the dictionary attack
fails will the attacker reluctantly move to what is called a "brute-force attack," guessing arbitrary sequences of numbers, letters and characters over and over until one matches.
These programs unleash the combined power of classic brute force attack, dictionary attack
and precomputed hashes attack using rainbow tables to recover a user password for the corresponding databases.
A dictionary attack
tries a range of words included in a previously compiled list, and tries it against the captured file till there is a match.
We now show that S-EA-3PAKE cannot protect clients' passwords against an offline dictionary attack
. Assume a malicious client C who wants to find out the passwords of A and B.
A thief can't readily decipher these hashes, but can mount what's called an automated offline dictionary attack
. Computers today can evaluate as many as 250 million possible hash values every second, Blocki noted.
However if the attacker steals the PVD, v, then she/he can mount an off-line dictionary attack
. SRP 6 is subject to server compromise based dictionary attack
We found that S-3PAKE is not secure against an off-line dictionary attack
. The present work reports this new (and more serious) security problem with S-3PAKE and, in addition, shows how to fix it.
