Cryptography is a very vast topic which contains many techniques to make the data secure. One such Cryptography technique is the public key Cryptography. In the public key Crypto Systems there are two keys, one is the Public key and other is the private key. The public key is made available to the outside world and is in confidential where as the private key is kept secret and is available only to a particular user. Here the public key is kept different from the private key. The public key is used for encryption whereas private key is used for decryption of the message.

As we know that Cryptography is based upon the encryption of the message at the sender side followed by its decryption at receiver side. This encryption and decryption is done by using a key. There are two keys, one at the sender side and one at the receiver side. In the key exchange Cryptography technique some information is exchanged between the source and the destination from time to time and ultimately the sender side key is exchanged with the receiver side key. So, we can say that the key exchange algorithms follow the symmetric key Cryptography approach as the keys used on both sender and the receiver sides are same.

Cryptanalysis is the converse process of Cryptography. Cryptography is science and art of making the message secret, where as Cryptanalysis is the art of cracking the codes and breaking the security. The person who performs the Cryptanalysis is known as the Cryptanalyst. The Cryptanalyst’s job is to decode the secrets either by hook or crook, he keeps on trying different combinations. The performance of a Cryptanalyst depends upon the time he/she takes to decode the data. It means that the lesser the time a Cryptanalyst takes; the better is his/her performance.

Cryptography is the art of secret writing. Cryptography is basically a technique which is used to enforce security standards on the data which we want to send through any network. When the data is going from source to destination then there may arise a case where some body can misuse the data, that data may also contain some important information which is not meant for anybody other than the receiver, so in these cases security becomes a must. At the sender side, the data is encrypted by using a key, and on the receiver side the encrypted data is again decrypted using another key to get back the original data. Note that the keys are kept secret. This concept of encrypting the data at the sender side and decrypting it at the receiver is Cryptography, which can provide security to the data.

Smart cards as the name suggest are a smart work of technology and biology. Well technology you all would have understood, but biology, sounds awkward, am I right. Biology is used because they are nowadays based on biometrics which is completely based on human biology. That is what makes smart cards completely spectacular and amazing cards to use and possess. These cards are really popular and in demand in Europe, America and Australia.

Biometrics is something that was not even a dream few decades back, but now we have this amazing technology in our hands to cater our needs. This is a extremely outrageous technological marvel that has combined biomechanics with electronics. You would be amazed by the security standards that can be set with the help of biometrics. Let us take a brief tour to the amazing world of biometrics security.

Biometrics is really a new age technology which is still in its childhood when it comes to awareness and accessibility. This technology will no doubt become the largest security providing technology in the times to come. We all know that Biometric devices use the physical and behavioral character of persons to validate their individuality. Some of the common traits that are used to differentiate individuals include finger printing, retina and eye iris, the voice and the facial impressions. Some of the biometric techniques can also find the individuality on the basis of digital signature of the person. Thus we can say that if someone passes a biometric security test then he or she is surely a genuine personality.

Visual Basics (VB) is a event driven programming language which has been developed by Microsoft. VB 1.0 was introduced in 1991. VB was derived from the simplest programming language BASIC, which resembles the high level language and is easily understood by the programmer. VB enables rapid application development (RAD) of GUI applications. It also enables the access to the database using other access methods and it also allows the creation of active controls and objects for various applications.

Ada is basically a structured language, designed under the contract of United States department of defense during 1977-1983. Ada is very much same as C and C++. Ada was given this name from the first computer programmer, Ada Lovelace. Ada find its most of application in embedded systems and real time systems in the initial stage but when its 95 version came in the market then it was suitable for numerical and financial programming also.

WiFi- wireless fidelity is the latest technology that is ruling the wireless world with its amazing possibilities. The technology is based on the traditional wireless methodology like the Bluetooth is. The term refers to connectivity of multiple users using one wireless network. This technology is mostly used for accessing internet when you are using a wireless device like a mobile phone or a laptop. Now you must be overwhelmed with the word, fidelity. Have u heard it somewhere? Ok, in high fidelity stereo systems. Yes it is the same fidelity, which refers to transmitting wireless data to the station antenna. This is what happens in WiFi, the signal reaches a small antenna that is placed near your work area. This antenna finally sends the signal to the device.
