Encryption software Essays

Have you ever felt like your privacy has been violated and you don’t know why? Privacy now a days is a very controversial topic, everyone wants privacy and protection but do not want the consequences that come with it. This is very similar to how privacy was being violated in the novel 1984, it takes place in a orwellian society where no one decides for themselves. There are two articles “That’s no Phone, That’s my Tracker” and “This Smartphone Tracking Tech Will Give You the Creeps”, and the novel

A. Encryption Concept Encryption is the process of using a formula called the cryptographic algorithm to translate plain text into an incomprehensible code and later convert it back to plain text [3]. The text relies mainly on the use of a numeric value, called the key, which is part of the encryption algorithm. B. Cloud Computing Concept Cloud computing has become part of users' lifestyles because sources such as data storage, and computer systems are accessible as needed through networks that

memory disks. You may want to “ clone” your computer hard drive, you would do this, because you would not want to mess up the hard drive that was on your computer. This also means that you would be copying everything this will including the operating software. Most of the evidence is usually found in the data files. If you do cloned

about why data storage encryption is important. http://www.computerweekly.com/feature/Encryption-techniques-and-products-for-hardware-based-data-storage-security might help} Encryption is the process of encoding a message so that it can only be read by the sender and the intended recipient. When electronic data is encrypted it is converted into another form called cipher text, which cannot be easily understood by anyone except authorized parties. The main role of encryption is to be able to safely

The so-called fully homomorphic encryption is considered the Holy Grail of Cryptography. Addition and multiplication are the main building blocks of computers, and the ability to make calculations on encrypted data without decrypting it, would lead to a whole new level of security. So, a company, for example, could send an encrypted database to a cloud computing provider, which would work on that data without decrypting it. If a customer wanted then to perform a search on their personal database

VP networks are the best solution for the company. Because it will improve productivity, extend geographic connectivity and simplify network topology with ensuring security, reliability and scalability. Also, VPN can be very convenient not like other methods e.g. leased lines that can get very expansive. There are two types of VPN: Remote-Access and Site-to-Site. Remote-Access: is when a company wants to connect its remote employees to the company private network this can be done using an internet

shown in Fig.1 which it uses a cover medium (It used to hold secret data inside), the secret message (the secret data that is to be sent), hiding method (It used to hide secret message inside carrier file and produce the result is Stego-file) and an Encryption algorithm (the procedure is to encrypt Stego-file). The result of the process is the Encrypted Stego file which is the encrypted digital image/video that has the secret message hidden inside. Encrypted Stego-file is sent to the receiver via communication

unauthorized individuals and others having their systems destroyed. Some surveys done in the recent past by Panko (2008) reveal that the most common types of threats to system security from inside a firm involve vulnerabilities and flaws existing in software applications, unintended leaks of data due to errors caused by human beings, and the theft or the loss of mobile and handheld

flaw in the Open SSL cryptography library which was exposed in April 2014. This flaw effected systems all around the world using SSL/TLS encryption at the time. The bug allowed anyone to read the memory of systems protected by these now outdated versions of OpenSSL. The Heartbleed bug is directly related to cryptography as it effected one of the largest encryption libraries in the world. OpenSSL is used to protect emails, instant messengers, and even secure VPNs. The bug compromised the secret keys

should make sure that his computer always uses the latest updated OS and also has some kind of antimalware software installed on his computer keep malware at bay. The computer should also be firewalled by either a hardware based firewall device which can installed before the server or on the router level which can easily block unwanted port scanning and network sniffing tools. Some software based firewalls such as ZoneAlarm, CyberOam, Sophos, products from Symantec and pfSense etc. can be used.

messages and work without a server by using its own network that does not rely on another system. Part of their aim is to avoid ads and spyware. From looking at some of the documentation it can be seen that they use Blowfish encryption which encrypts up to 448-bit and RSA encryption up to 2048-bit. The program begins by asking for you to enter your username and password to connect to BitWise. As you type your passwords it hides each character. After entering your information

user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand. In the present era everyone needs fast processing and less space required to store results in computation process as well as security of information. There are many encryption algorithms in which some of these take more computation time, some

What is Unicode SMS? The term “Unicode SMS” refers to text messages sent and received containing characters not included in the default GSM character set. GSM stands for Global System for Mobile Communications (originally “Groupe Spécial Mobile”), and the GSM character set is a collection of the 128 letters (A-Z), numbers (0-9) and symbols (i.e. @, ?, !, &, etc.) most commonly used in mobile communications. Because GSM was developed in Europe and uses 7-bit binary code, it has its limitations. For

Walmart is one of the biggest company in the United States. The company is worth nearly $260 billion, as well as having to managed more than 5,000 stores in 10 countries around the world and employed approximately 1.5 million workers. Unlike others, Walmart developed its purchasing power by eliminating the middlemen and building direct relationship with the suppliers. In addition, the company purchases the products in bulk directly from suppliers at a lower cost and then sell items in stores at

Public key cryptography is an asymmetric method that use a pair of keys for encryption: a public key which is used to encrypt data, and private, or secret key is used to decryption. It requires that a person must have a pair of public key and private key. The public key is distributed in the open so that anyone wishing to communicate

4. Strong collision: given a message M1, it is not possible to find two distinct messages such that h (M1’) = h (M1). The probability of this collision is 2n/2. Hash function is used in message authentication which uses a secret code before hashing so that no one else can modify the message and hash and then can encrypt the message for confidentiality. There are several ways of applying hash for message authentication: 1. One is to apply hash to the message and encrypt it and decrypt it using the

In order to make the cloak invisible, Light from all directions travel through the object, rather than hitting it. Because of not being able to interact with light, the hidden

Effective password policy is needed to prevent the passwords from being guessed or cracked. The password policy covers the passwords of all types via passwords of users, systems, databases, applications, etc.., while the password policy can be enforced where they are used frequently and by users, it is difficult to enforce for the passwords used in application to application communication. This article talks about the challenges and possible solution to eliminate embedded passwords in application
