Data Security — Essay Sample For all corporations, businesses, government programs and even individuals, data protection is fundamental to preserving integrity, profits and records. Without data security, people are at risk for identity fraud, theft, destruction of property and much worse. General data security seeks to protect an individual database or group of databases from unapproved access, tampering and destruction. This preserves individual rights and upholds many national and international laws, which strive to preserve the integrity and ownership of different databases.
Cryptography algorithm using data structure using C concepts for better security Essay: For secure communication we always use different security algorithms e.
In graph we have graph traversal i. This paper presents the new technique for security which is combination of Caesar Cipher and graph traversal, Binary search tree together then security will be much higher than only using Caesar cipher or graph traversal or binary search tree.
In BFS, we traverse level by level . In cryptography, many algorithms are available for protecting our online important information which we are transferring from one person to another person .
One of these algorithms is Caesar cipher. It is very basic algorithm.
In Caesar cipher we replace corresponding letters left or right by some number . In DFS, we select some node and go as deep as possible and we use concept called as backtracking here . Using graph traversal we can reach each and every vertex of the respective graph and for this we use BFS and DFS methods.
Take first character from the word evaluation and e has 5th position in the alphabet series. So our 1st character is f. So using above formula we got words as: Give numbers to each characters.
Arrange the above position of characters in the alphabet in ascending order. Ascending order of fwbmvbujpo word: Divide each word into 2 equal parts according to the numbers given in step 3. Lesser than or equal to numbers will go to left side and greater elements will go to right hand side just like binary search tree .
Each left and right hand side node has at the most 2 children. Draw diagram for the word position and its numbers. Figure out cipher text i. Write down values from each circle from the figure 1 and 2 in such a way that we will get the cipher text as below: Cipher Text for the words fwbmvbujpo and ufdiojrvf respectively are: Take the cipher text Cipher Text: Figure out position of each character in the alphabet series and position number of the character in the respective word from the cipher text.
From the chart drawn in step 2 of decryption, we can find out plain text. Consider position number in the word and position of characters in the alphabet.
Position number in the word: Apply Caesar Cipher Here rule used is position of the character in the alphabet-1 … 2 e. So our 1st character is e and using this formula we got plain text as: When we use Caesar cipher with some concepts of data structure using C then result obtained is much harder to detect than only using Caesar cipher or some concepts of data structure using C.
We got both plain-text i.
So security is maintained. Essay UK - http:With numerous online threats to both your data and your identity, your computer's security systems are vital. Despite the necessity of strong digital security, the fact remains that no security system is perfect.
40 Information Security Essay 2 Concepts and Terminology for Computer Security Concepts and Terminology for Computer Security 43 Lampson [LAMP91] stated more flatly that access controls provide a foun-dation for confidentiality and integrity, but are less useful for availability.
Back when computers stood alone on desks, unconnected to the rest of the world, computer security was simply a matter of locking an office door, putting a lock on the power supply or installing a security software package. Today, the rules of computer security are changing, and in years to come, it.
The Computer security is one of the most popular assignments among students' documents. If you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples.
Computer security is quite a rare and popular topic for writing an essay, but it certainly is in our database. Computer security is not an issue for organizations alone.
