Cryptovirology - Ensure the Confidentiality of vital data!

Today, cryptography is everywhere with the progression in science and technology. Most of the users are making good utilization of cryptographic primitives. Here, the importance of differentiation between cryptography and cryptanalysis comes into the picture. Basically, cryptography is defined as a defensive science whereas cryptanalysis is an offensive one. This advanced science is used by the virus writer as well, in order to ensure the confidentiality of virus' payload. It helps to avoid the detection and analysis of malicious code of virus. There is another important term known as cryptovirology. It is entirely opposite to the concept of cryptography, since it utilizes offensive methods for protection purposes. Generally, it is considered to be the study of applications of cryptography to malicious software.

There are numerous elements that can infect your system such as computer virus, malware, Trojan, worm, spyware and adware etc. Computer viruses are considered to be the most annoying and extremely destructive elements for the security of system. It can get attached to one of your files and spreads to other files and documents. Viruses cause damages to files, software and hardware. Crypter is a program that makes the anti-virus unable to detect the viruses. Apparently, worms are similar to the viruses but the horror is that it spreads automatically. They have tremendous potential to cause heavy traffic, clogging networks and slowing down the entire internet.

Another dangerous aspect of internet is malware infection. This harmful infection of computer is obtained by using unprotected PC online. It can disable the computer system and prevent it from installing the preventative measures. It is malicious software that is installed without the permission of the user. Different types of infecting elements infect a computer in different ways. There are various malware research labs that are finding solutions to combat these harmful information stealers. In these labs, highly skilled professionals are trying vigorously to protect the system from harmful agents like viruses and worms.

Cryptography literally means secret writing. The cryptographic algorithms ensure the confidentiality, authentication, and integrity of the vital messages. Mostly, the anti-virus vendors utilize it to ensure the security of important data. It is believed that cryptography is a double-edged sword to make you safer, but is also used for some malicious purposes within the sophisticated viruses. In order to perform the legitimate act, malicious cryptography should be avoided at any cost. The advancement in technology also introduced cryptanalysis that involves complex mathematical theories. These critical analyses are done by the professionals only.

Traditionally, cryptography is used for the defensive purposes. It can prevent the loss of access to information, loss of confidentiality, and vital information leakage. But the forward engineering discipline of cryptovirology is attacking in nature, instead of defending. However, crypto virus is known to be a computer virus that contains and uses public keys, in the computer security. If you want to protect your system from sudden calamity like loss of important information, then start exploring the efficient tools and services.
