Originally based on S/KEY, a seminal OTP system developed at Bellcore, OTP (One-time password) technology is a system that requires a new password every time a user authenticates. This basic principle of an OTP solution effectively protects the system against replay attacks, or…
The new passwords are generated by the system using a one-way hash function (Bhaiji, 2009).
Challenge/response: This type also uses mathematical algorithm, but with a challenge function. In this type, the user needs to generate a one-time password by entering a challenge (a random number or secret key), received at the time of login, into the password-generating token/software. Since new passwords are based on a challenge mechanism instead of being based on previous password, this type offers more security as compared to mathematical algorithm type (Bhaiji, 2009).
Time-synchronized: In this type, passwords are generated by the system using a physical hardware token that has an accurate clock synchronized with the clock on the authentication server (Bhaiji, 2009).
OTP technology is a type of multifactor (two-factor) authentication access control which provides strong user authentication for secure access. Two-factor authentication refers to the combination of any two of the three basic forms of one-factor authentication mechanism: something the user knows such as a password, pass phrase or PIN (personal identification number), something the user possesses such as a smart card or access token (hardware or software), and something physically unique about the user such as a fingerprint, voice, retina or iris scan, or DNA sequence (Samuelle, 2008).
If the intruder is able to guess a randomly generated OTP somehow, he will be able to access the system only once because subsequent access would require him to get lucky again guessing a randomly generated OTP.
The major problem of OTPs is that no user can ever able to remember them because they are generated in bulk and stored in a file on a system. Therefore, OTPs are vulnerable to eavesdropping because if someone knows that the passwords are stored in the file, and then he can gain unauthorized access to the user’s account where he can then install keystroke-capturing ...

The research discusses the Rainbow table technique. Its introduction follows a detailed discussion of a rainbow cracker tool. How that tool uses rainbow tables to retrieve passwords has been taken into account. Screenshots of Brute-force cracker and rainbow cracker are given at the end of the report.
Introduction Authentication is one of the vital steps involved in providing access control (Tipton & Nozaki, 2011). Authentication is the process through which a system verifies whether a person is actually who he/she claims to be. Throughout the course of history, humans have been using some means of authentication in their day to day dealings.
There are potential hazards present on the internet just as there are beneficial elements. It is therefore recommended that the personal information relative to a person's security and personal use is kept safe so that it may not be altered by any spammers or malware.
Password cracking is a way of trying to access or crack passwords in an attempt to enter into a computer system or a communication network. Crackers usually make use of a range of scripts, tools or cracking software to break a communication system password. The prime objective is to perfectly get the password of server or other system.
It has been noted that time management is a thread running through all aspects of teaching (Nelson & Low, 2011). It determines various activities such as organizing the day, deciding how often and how long various subjects are to be taught, organizing classroom, recording the progress of students, and how to reduce keep time-consuming behavioral problems.
What is required now is a vision to change one’s basis when it comes to time and manage things according to priorities.
