Cyber laws are getting stiffer and stiffer. In US and other developed countries cyber laws are very strict and those who are caught as guilty has to pay hefty amount as fine with imprisonment. Even in fast growing nations like India Cyber laws are tightening up. However cyber laws in India is not so robust yet. Piracy is one of the offspring of cyber crimes. You can download almost all the movies released anywhere in the world from internet. Even American movies can be downloaded online. Ususally cyber criminals take advantage of the weak cyber laws in many countries due to which they out of reach of those nations who have strict cyber laws. 99.99% of websites offering free or paid downloading of audio, video songs or movies are either breaking copyright policies or they are contributing to piracy. Peer to peer software such as bittorent, uttorent etc are very commonly used for downloading movies or any other copyrighted data. But how would you feel if producer of a movie declares that his movie will be available on the internet for free downloading. Shocked!!

  Even I was shocked, but it is true. Much talked upcoming bollywood movie 3 Idiots by producer Vidhu Vinod Chopra is going to be released tomorrow i.e. 25th december,2009. Speaking to reporters producer anounced that internet used can now download his movie through youtube after 2-3 months of release so that it does not ruins the theater and multiplex business. 3 Idiots is releasing tomorrow in 1,766 screens world wide out of which 366 are in 32 countries. This is the largest international release for a Bollywood movie. Amir khan, the actor, has been on his toe and wandering all over the country promoting his new movie. The movie is based on the bestseller novel ‘Five point someone’ by Chetan Bhagat. The decision of distributing the film for free online is first ever decision of its kind. The decision has been taked to crub the ghost of piracy.

Virus is again in news for the damages it cause due to its unrestrained spread. This time it is not only the biological virus H1N1, but also the computer virus. The two virus namely Conflicer and W32 Nimda infected the servers which was being used for conducting CAT exam, entrance test for IIMs. Basically these are worms which mostly come either from USb drives or the internet. Needless to mention that they affect MS Windows operating system. If you search about these worms in Wikipedia you will find that Conficker exploits the flaw in Windows to take over machines and link them into a virtual computer that can be commanded remotely by some other person or program. You will be amazed to hear that there are nearly seven million computers now under its control—government, business and home computers in more than 200 countries.

Even W32 Nimda is known for its highly propagative nature. The most astonishing part is that Windows has already released patches against these worm but Prometric, the US based firm responsible for all the technical aspects of the online test, perhaps did not take it into their consideration.

Every company, specially in IT/Software company heavily relies on Security Token with one time password feature. Wherever security and privacy is an issue security tokens are used. Security token is nothing but a very small crytographic device which you can carry inside your pocket. It is like an electronic key to access private or confidential data. Some of these devices are like you credit cards or ATM cards with cryptographic keys like digital signature and biometric such as fingerprint minutiae. However some more advanced tokens may include small size key board on it which can be used to enter the PIN and generated the password to access the system. Some devices even come with USB, Bluetooth or RFID functions.Generally tokens come in four varieties. Some uses static password and some device uses synchronous Dynamic Password. There are devices which uses asynchronous password as well as challenge response.

These devices are not very simple as they make use of compex cryptographic algorithms. Moreover the password generated by these device are for only one time usage. That is why they are often called One Time Password or OTP. OTP algorithms uses different approaches to generate the random passwords:

One approach is to use a mathematical algorithm to generate a new password based on the previous password. So the generated passwords follows the chain and are used in predefined sequence.

Another effective approach is based on time-synchronization between the authentication server and the client providing the password. In this approach the passwords are valid for only short duration of time, say 3 minutes. Moreover, it is impossible to guess the next password even if you know know the current password.

One more approach is to use mathematical algorithm where the new password is based on a challenge.

I studied about various cryptographic techniques and algorithm during my engineering and was always curious to know more about it. Practically using these devices and understanding their importance is a wonderful experience for me. RSA and other cryptographic algorithms are highly used in web environment for authentication and secure trancations (like in htpps urls). OTP is yet another wonderful application of cryptography.
