A USER AUTHENTICATION PROTOCOL RESIST AGAINST PASSWORD ATTACKS USING ANDROID MOBILE

摘要

Password attacks like password stealing and password reusing causes high vulnerabilities like loss of perceptive information of the user. A protocol which uses the personal device like mobile to reinforce the authentication of password from the adversaries, is get implemented as Opass. By the use of cryptographic algorithms, the authenticated passwords get passed to the mobile and server over the communication channel. Opass generate a one - time password for every login of the authorized user with time durability. Usage of mobile network reduces the risk of eavesdropping and password thef ting. One time password acts as the defense mechanism against the password stealing attacks.
