Is encryption on smartcards actually used?

Smartcards work with 2 part keys - asymmetric keys.  One part is publicly available and can be used to encrypt data. The other is locked on to the smart card and must be used to decrypt data encrypted with the public key.  The key on the smartcard is called the private key.  You can see that using this method of 2 keys it is possible to encrypt something and ensure that the only person able to decrypt it is the holder of the smartcard containing the corresponding private key.\n\nYou are correct in your assertion that performance would be an issue if the smartcard had to encrypt/decrypt everything.  So all the smartcard does is decrypt symmetric keys.  The computer that it is connected to then does the heavy duty job of decrypting/encrypting the data.  In the case of a VPN the symmetric key is changed frequently and is usually referred to as the session key.  When a VPN connection starts up part of the process is for each end to agree a session key.\n\nThe Smartcard does have other functions such as Authentication etc but hopefully this will answer your question about the encryption etc

windows xp pro has added security and additional encryptions for pc users to secure their privacy whether it may be financial documents or among other things that may require typing of passowrds just to get to the place that you're in

With Windows XP Professional, you can help protect private customer and financial information by using its Encrypting File System (EFS).\n\nTo encrypt a file or folder\nClick Start, point to All Programs, point to Accessories, and then click Windows Explorer.\nRight–click the file or folder that you want to encrypt, and then click Properties.\nOn the General tab, click Advanced.\nSelect the Encrypt contents to secure data check box.\nEncrypt contents to use secure data \nApply to changes to this folder & subfolders & files . hit on ok \n\nTo decrypt a file or folder\nClick Start, point to All Programs, point to Accessories, and then click Windows Explorer.\nRight–click the file or folder that you want to decrypt, and then click Properties.\nOn the General tab, click Advanced.\nClear the Encrypt contents to secure data check box.

If you are talking about your personal connection at home, you dont scramble it as such... you need to encrypt the signals using the WEP encryption feature (if your router supports it).

Not very practically.  If you want to do more than say a folder take a look at this\n\nhttp://www.truecrypt.org/\n\nGota love open source.

Correct.  Your information can easily be intercepted, but because of the encryption cannot be read.

If the card has been demagnetized, nothing will make the card work.  All of the credit card's information is contained on the magnetic strip on the back of the card.  If the credit card is demagnetized, the info is lost and the card will not work during a swipe in a card reader.\n\nHowever, if the card is slightly scratched - enough for it not to work in the card reader, a piece of paper of plastic bag may work to prevent the card reader from mistaking the disturbance in the magnets (microscopic magnets in the strip) for actual credit card data.

I would say totally appropriate, probably 99% of weddings I've been to in the last 5 years have had some type of drop-box system for the cards.  Keeps from other people stealing them!

You must be careful about the encryption in the page where you're sharing your personal info. Don't share ur credit card numbers unless the site's reputed n has 128 or 256 bit encryption!!

A financial transaction on the internet can be routed through any number of systems throughout the world before its destination.  At any of these points, a sniffer can be checking the data for number sequences common to credit cards and expiry dates. If these numbers are extracted they could potentially be used by someone other than yourself.   It is therefore necessary to make sure that your data is protected during it's journey.\n\nTo protect your data a secure server is used.  The secure server works in conjunction with your browser.  When your send your order, the browser scrambles the data.  The data  passes through the internet and is unscrambled by the secure server. During the data's journey it will not be recognizable by any third party and as such is secure.  \n\nA secure server uses a special protocol called https instead of the more familiar http. When in use the URL will be preceded by https:.  To support a secure socket layer (SSL), the sever must have a "certificate" signed by a company called Verisign.  The servers used by Flexisoft have this certificate. \n\nThis method of security is not just used for shopping carts but also used by financial institutions who now allow you to "Bank-on-line"\n\nBrowsers\n\nYour browser must support SSL.  Either Microsoft® Internet Explorer 4.0 or higher OR Netscape Navigator® 4.0 or higher, support secure transactions.  To download the latest version of the either of these browsers select the icons below.

Your supposition was correct. All information transferred is encrypted. The performance is not as bad as you might think because public key cryptography is only used to securely transfer a symmetric key which allows the data to be transmitted securely and without a lot of overhead.

Of course there is!\n\nIt is on the back of the card!

There is no secure "password scheme" that doesn't involve some sort of encryption. If you don't have encryption, your data is on the disk "in the clear." Anyone with a binary disk reader can easily get it.\n\nTake Windows, for example. Windows doesn't use encryption to protect your files, but it can be configured to password-protect your account. There are hundreds of programs available that can easily reset a Windows password and give anyone access to your files.\n\nEncryption software is no more complex than your word processor, and some encryption software is user-friendly (PGP, WinZip). If you want to keep your data secure, you need encryption.

I voted on a diebold machine and felt it was safe and accurate.\n\nHowever, if someone really tried and knew what they were doing, fraud could be an issue with those machines. Better safeguards are needed in the future.
