Information Security: A Case Study
Security is the most important part of information exchange and data storage in any network. Especially in today’s world when education, business and all other transactions are spreading over internet technology, security is an important concern where there is always a high demand for efficient and effective encryption algorithm. There are many predefined algorithms like AES, DES, IDEA, RSA etc.. But as the levels of security increase the time, speed and complexity also increase thus, reduces their efficiency. In this paper a multilevel of multiple encryption schemes has been proposed, which enhances the security of the algorithm. This will be much simpler to implement and hard to crack as well as give proper security to the information transferred. …show more content…
Hence, data security is critical for most businesses and even home computer users. Payment information, Bank account details, Client information, Research & Development files, Confidential files, Personal files can be hard to replace and potentially dangerous if it falls into the wrong hands. When the data is lost to hackers or a malware infection, it can have much greater consequences. Security in terms of confidentiality, integrity, authentication, non-repudiation, access control and availability is measured. Considering the above parameters, Cryptographic algorithms and protocol are very useful to keep a network system secure. “Cryptography” is an art and science of providing information by transferring it into an unreadable format which can be only read by the expected receiver having the secret key to break the message. It can be defined as a science that applies complex mathematics and logic to design strong encryption …show more content…
Symmetric keys used for encryption and for decryption are the same. The secret key should be known to both the sender as well as the receiver. The difficulty in this approach arises in the distribution of the key. It is generally categorized as being either stream ciphers or block ciphers [13, 14]. RC5 algorithm makes use of magic numbers [15]. Due to the data-dependent rotations, differential cryptanalysis and linear cryptanalysis is not possible. The key used is strong if it is long. However, if the key size is short, then the algorithm is weak

343 Words | 2 PagesThe owners or users are those who would like to outsource their data in public cloud to S-CSP then it access that stored data later whenever required. In this system of storage, in support of Deduplication method, a user uploads only unique single data copies/files although it is impossible for them to upload any duplicated data files. In this system, each of user who has concerned with set of level of privileges i.e. privilege levels (e.g. upload, download) is the settled down in the system. Each file is said to be safer or protected by having both the keys named CE key and PE key. These keys used for understanding the Deduplication with user’s authorization with differential privilege levels.

The first classification is based on the place where ID systems can be placed and the second one is based on analysis of the technique used. These ID systems can be classified into three main groups starting with Host Based Intrusion Detection System (HIPS), then Network Behavior Analysis (NBA), Network Based Intrusion Detection System (NIPS), and Wireless Intrusion Prevention System (WIPS). The WIPS it analysis the traffic of wireless network, NBA examines traffic to identify threats that generate unusual traffic flow, HIPS monitor single host for suspicious activity, NIPS it analyzes the traffic of entire network.

In order to solve this problem metadata is stored for each server content into proxy server. 7. Suppose size of data stored in server 1 is 2GB and similarly size of data stored in server2 is 2 GB.

710 Words | 3 PagesOther protocols such as secure socket layer (SSL) which operates at the transport layer enable server authentication as well as client authentication and encrypted communication. Using SSL, we could ensure that the information being sent from our companies’ server and any remote clients is secure. However, it is worth pointing out that SSL has a successor known as transport layer security (TLS). As a successor to SSL functionality, wise TLS is very similar. Some of the improvements made in TLS at least TLS v1.2 include less vulnerabilities compared to SSL as well as new algorithm’s .

Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders.

862 Words | 4 PagesThis method works good for small universe of keys since the dynamic subset of keys that the application draws from the universe might not contain all the keys. This lefts a lot of unused slots if the universe is large and subset of keys drawn are small. Also if the universe is large, it would be difficult to have a large table of size |U|, since we might encounter space issues constrained by the memory size of the machine. However, this method is having the advantage that the worst-case computational complexity to check if an entry is present in the table is only

According to the book, the 9th century scholar, Al-Khindi of Baghdad, noticed “certain letters were used more frequently than others” (p76). This idea turned into the well-known code-breaking method of “frequency analysis,” which substitutes the letters in a message with other letters or

459 Words | 2 PagesThe encryption key (public key) does not have to be secret and anyone can use it to encrypt data. However, the corresponding decrypted key (private key) is known to a single entity that can decrypt data encrypted with the encryption key. When we need to send an encrypted message to someone else, we first obtain the person’s public encryption key and transform the message with it. Only the recipient knows the corresponding private key. The recipient can decrypt the message.
