Baappay | What Are Some of The Different Card Data Encryption Techniques?

Baappay | Data encryption is needed so that the information that is contained on a credit card does not fall into the hands of an unauthorized party. To protect the identity of the cardholder data encryption is used. This simply means that the information is displayed in such a manner that someone who does not have the proper software to decode the encrypted information will only see symbols, not the actual letters and numbers.

One method of data encryption is known as hashing encryption. This is likely the first type of encrypting that was done to protect the information on credit cards. Hashing creates a fixed length signature using an algorithm. One of the reasons that hashing is so good at keeping information private is because a minor change in the message that is being transmitted will cause major changes in the way the hashes appear. This method quickly alerts you to the possibility of tampering.

There are two other basic data encryption methods used and hashing is different from them because once the information is encrypted with hashing there is no way to reverse the encryption. Two of the most frequently used hashing algorithms are the Message Digest 5 and the SHA or secure hashing algorithm.

Another popular way to encrypt the information on credit cards is through symmetric methods. This type of encrypting is often called private-key cryptography because there is a "key" that contains the knowledge of how to decipher the encryption. The key to this type of cryptography must be protected because when the sender sends the message in this type of text and it is intercepted, all the hacker needs is the key and they can decipher all of the information. Since the sender and the receiver both need the code to send and to read the message there is a large chance that the information could be leaked to other sources.

There are three types of cryptographic message transmission that are used heavily. The advanced encryption standard, the international data encryption algorithm, and the data encryption standard are the three most frequently used of the symmetric methods, but the symmetric methods allow you to stream the message or encrypt blocks of the message at a time.

Asymmetric cryptography sounds at first like it would be less secure than symmetric cryptography because asymmetric cryptography has a public key that is freely available to anyone. Actually, asymmetric cryptography is more secure than symmetric cryptography because it requires two keys for the message to be sent and then read.

The public key allows anyone to send the message in code, but you are required to have a private personal key in order to decipher the coded message. RSA and Diffie-Hellman are two examples of algorithms that use the asymmetric cryptography to send information that is sensitive.
