Encrypted Chat I am generally interested computer science and computer security so as I researched those fields I found out that it is easy to steal unencrypted so I researched what encryption and decryption really meant. After my research I found out that these are main points that classify encrypted and unencrypted information. So when we send unencrypted information 1. We type message and press SEND button 2. It is sent to server and when we send encrypted information 1. We type message and press SEND button 2. Message is converted to random numbers, symbols and letters 3. It is sent to server  This is simple demonstration of client server relation. So during first example if we send “Hi how are you” this text will be send to server as it is and client will receive the message you sent. During Second example when you type “Hi how are you” it will be first encrypted on your computer and something like this will be sent to server “VlHTRKpo87NGwQWOjbUUA3SlWqU1t/QkKzihAREzxUCWEfgY96K3Hw==” And then client will decrypt this informatio...

    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.

    In this process of end to end encryption, the unauthorized users such as service provider or any intermediate person can’t decrypt or read the communication between the sender and receiver. In the present day, Service Providers have access to our communication but when we deploy the end to end encryption then the service provider can intercept the communication but can’t read the content of our communication and the common example is WhatsApp messaging service. We can also secure our emails by using PGP encryption technology.

    On 5 October 2009, computer equipment from a network data closet was stolen from BCBST. The items stolen were 57 unencrypted hard drives which contained over 300,000 video recording and over one million audio recordings. According to Whitman & Mattord (2010), confidentiality, integrity, and availability makes up the C.I.A triangle which is the basis of Committee on National Security model for information security, an industrial standard, (Whitman & Mattord, 2010). Confidentiality can be a synonym for encryption but also means only the people with the correct permission can access the information. One of the major security issue is the hard drives were not encrypted. The hard drives should be encrypted to prevent people from reading the information the computer. Software can be purchased which will encrypt files on hard drive with such as Folder Lock, SensiGuard, Secure IT, and more. There are open source encrypting software which are free for use which could have been used. If the hard drives were not needed, the data should hav...

    Information security plays a central role in the deployment of modern communication systems. The most important objectives of information security are authentication, confidentiality, data integrity and non-repudiation. Confidentiality ensures that information is accessible only to those authorized to have access. Authentication is the process proving the identity that assures the communicating entity is the one that it claimed to be, this means that the user or the system can prove their own identities to other parties who don’t have personal knowledge of their identities. Data integrity ensures that the received information has not been altered in any way from its original form. Data integrity safeguards the accuracy and completeness of information and processing methods. Non-repudiation is a mechanism used to prove that the sender really sent this information and the information was received by the specified party, so the recipient cannot claim that the information was not sent. Communication systems are widely interconnected and interdependent and use the same technologies to create a uniform digital world. In this era of digital information system resources are not safe from attacks. Public and widespread use of digital tools in communication quickly causes the creation of secure mechanisms. Cryptography technique is one of them. Cryptography is the basic encryption method used in implementing security. The word cryptography comes from the Greek word "Kryptos", that means hidden, and "Graphikos" which means writing. Cryptography or communication by using secret code was used by the Egyptians some 4000 years ago. However, the science of cryptography was initiated by Arabs since 600s. Cryptography becomes vital in the twentieth...

    Computer science is a vast field that includes nearly everything relating to computers. Everyday there is information transmitted all over the Internet. Pictures are uploaded, transactions are made on thousands of online retail websites, and banking transactions take place everyday on the Internet. All of these transactions have created a need for secure communications. People wish to keep things like banking, medical, and political information from the eyes of unwelcome parties. This has created a need for cryptography. Cryptography is the science or study of the techniques of secret writing, especially code and cipher systems, and is used by everyone from the average citizen to the government and military.

    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.

  • What Is Encryption And Decryption?

    1867 Words  | 4 Pages

    Cryptography is the common term given to the art and science of keeping the text messages secret. It is not the purpose to evaluate in detail any of the mathematical algorithms that are used in the cryptographic process, but instead to provide a general view of the process and its uses. To introduce briefly one of the fundamental building blocks of all network security, one must know the process of encryption and decryption. A process that transforms the given information (the plaintext) into a seemingly meaningless form (the ciphertext) using a mathematical algorithm and some secret information (the encryption key). The process of decryption revokes this transformation using a mathematical algorithm, in conjunction with some secret value (the decryption key) that reverses the effects of the encryption algorithm. An encryption algorithm and all its possible keys, plaintexts and cipher texts is known as a cryptosystem or cryptographic system. Figure 4 illustrates the process.

    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:

    Communication is an interdependent process of sending, receiving, and understanding messages. The definition implies that the components of the communication process cannot be examined separately. Rather, the relationship exists between the sender and the receiver, as well as the environment of the communication event, must be viewed as a whole. According to this perspective, if any of the components and circumstances change (that is, the number of individuals involved in the interaction, seating arrangements, or the time of the day) the communication event is altered. Communication is an ongoing process; we never stop sending and receiving messages. As we will discover, communication is a dynamic process, a process that changes from one communication setting to the next. Although it is difficult to predict, the ways of interpreting communication, certain components are always present in the communication process.
