Recommended: An Easy To Understand History Of Cryptography

In this paper there are two main types of cryptography symmetric and asymmetric encryption. Thought time Cryptography has evolved rapidly during world war one and world war two the allies used it to send messages between one the other. Symmetric algorithms encrypt and decrypt with the same key. Main advantages of symmetric algorithms are their security and high speed. Asymmetric algorithms encrypt and decrypt with different keys. Data is encrypted with a public key, and decrypted with a private key. Asymmetric algorithms (also known as public-key algorithms) need at least a 3,000-bit key to achieve the same level of security of a 128-bit symmetric algorithm.
Asymmetric algorithms are incredibly slow and it is impractical to use them to encrypt …show more content…

Cryptography is the science of encoding and decoding information the practice has been used for centuries from sending secret message from military generals to keeping your password safe from entering to your email or Facebook. Cryptography long time ago we can trace them back to the pharoses when they wrote on their tombs and walls and were later decrypted.

What do we know about symmetric Encryption?
Symmetric encryption is using one key to encrypt or decrypt your data. There was no verification to prove the person that used the key because there was only one key. It was also easier since only one key was in use, by having one key now it’s easier for the hacker to intercept the message. This was the only kind of encryption publicly known until June 1976
What are types of symmetric Cryptography and what is recently being used?
Types of Symmetric Cryptography Algorithms such as DES, 3DES, IDEA, Blowfish,
RC4 RC5, RC6 and finally AES are the evolution of the Symmetric encryption. Currently we are using the AES also known as the (Advanced Encryption Standard) it is used by
US government to protect classified information and is implemented in software and hardware throughout the world to encrypt sensitive

    Since World War I and World War II the military technology with regards to communication has increasingly improved. Years ago, if a message was conveyed it was likely to be delivered on foot or horseback. Communications using modern equipment began once the US Army Signal Corps was established. World War I took place before the modern radio. When dispatch riders were not being used to deliver messages, morse code with the use of the telegraph was the more advanced form of communication during that time. The main problem with

    What is encryption? Encryption is a technological technique that protects and secures the transfer of plain text information between two sources through the use of the internet. This is done by rearranging the text using a mathematical algorithm that renovates the message into an indecipherable form, which can only be unlocked and translated with a use of a key. The strength of the encryption key is measured by its length, which is determined by the number of bits and by the type of encryption program.

    Asymmetric Encryption is used to protect the data while in movement. Asymmetric Encryption is also known as Public Key Encryption. It uses two related keys, a public key and a private key which is not shared with anyone. This pair of keys are developed by mathematical methods which can be solved in one direction. So anyone can encode a data using the public key but only the user with a private key can decode that specific data. The length of Asymmetric Key Encryption is normally 1024 or 2048 bits. However, in Asymmetric framework the keys with smaller than 2048bits are considered as not safe to use.

In this way, we call it a key generation mechanism (key generation scheme).

    PKC is the enabling technology for all Internet security and the increasing use of digital signatures, which are replacing traditional signatures in many contexts. However, RSA is better than PKC because RSA doesn’t need digital signature. As a result, the RSA algorithm turned out to be a perfect fit for the implementation of a practical public security system. In 1977, Martin Gardner first introduced the RSA system. After 5 years, company RSA used secure electronic security products. Nowadays many credit companies of all over the world use the RSA system or a similar system based on the RSA system.

  • The Definition and Importance of Data Encryption

    2007 Words  | 5 Pages

    Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors. They also have many business files or contracts that need to be strictly protected. Without data encryption, these important information may fall into wrong hands and be misused by others. Besides, data encryption may be used to secure sensitive information that exists on company networks, or create digital signatures, and help to authorize in business. No one should underestimate the importance of encryption. A little mistake in encryption may make sensitive information revealing, or even result in illegal and criminal accuse.

    Data encryption refers to the transformation of data into a structure that makes it unreadable by anyone without a secret decryption key. It ensures that messages can be read only by the planned recipient. Encryption is the procedure of obscuring information to create it unreadable without special information. Only organizations and individuals with an abnormal need for secrecy have actually made good use of it. Nowadays, encryption is one of the most important technologies for maintaining your privacy and the security of important information. This helps out greatly especially when E-Commerce is being used.

    In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
