Module 6 Assignment Wendy E. Atkinson Saint Leo University Abstract This paper identifies several topics such as the type of protocols and cryptosystems used to complete online financial transactions, the development and implementation of Advanced Encryption Standard (AES), a fire control system in an automated server room, factors considered when converting general office space to a server room, and power systems in server rooms. Research indicates the use of secure hypertext transfer protocols and
Data Encryption I. What is Data Encryption? Data encryption describes the transformation of plain text into a different format that is meaningless read by human eye without being decrypted, so called cipher text, in order to prevent any unauthorized party to obtain information from the document. According to the Webster dictionary, “cryptography is the practice and study of data encryption and decryption - encoding data so that it can only be decoded by specific individuals.” Crypto is
effectively ending any leak of information. Early code involved ciphers (keys) that simply moved the alphabet over a couple of letters by a set amount that both the sender and recipient would both know. While that sort of encryption can easily be cracked today, we have many advanced methods to shield our outflow of information. Cyber security is a huge field in computer science that will only grow as human come up with evermore-complex coding methods. II. FUNDAMENTALS Three main ideas exist in cryptograph
credit cards, family heirlooms, etc. as well. It would be anarchy, it would be disastrous. In America today, citizens generally feel safe. We feel safe not only from our neighbors, but also from attacks by foreign countries. We have the most advanced military defense systems, and we've proven ourselves to be a powerhouse in recent years like in the Persian Gulf War. For a while, many of us perhaps even felt like America was invulnerable. On September 11 of this year 2001, we learned otherwise
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
secure access to its organizations network. Companies that have used these technologies are paving the way for future security methods. Encryption and decryption are always used whenever secure sites are accessed so that users that enter information can not be accessed by unauthorized people. 56 bit used before and the 128-bit encryption is becoming the standard at the moment. Many companies who conduct business electronically have the responsibility of making sure that when payments are made
there is no time delay which is experienced about the encryption and decryption of information (Minaam, Abdual-Kader & Hadhoud, 2010). What's more, the symmetric cryptography always realizes the part of validation because any data encrypted utilizing a single symmetric key cannot be decoded utilizing another kind of symmetric key. In addition, the symmetric cryptography can be more effective when the symmetric key is secret in the encryption of the communication. 2. The second nature of the symmetric
Security is defined in three main areas: confidentiality, integrity, and availability. Each definition takes a corner of a triangle, which is supposed to emulate a perfect security design called the CIA triad. I will refer to these elements in the recent Target breach. Target had a catastrophic security breach in December that involved 40 million credit cards, CVV numbers, and customer information (Greenberg, 2013A). Several weeks later the number of stolen credit cards rose to 70 million and
The AES encryption algorithm is a block cipher that uses an encryption key and a several rounds of encryption A block cipher is an encryption algorithm that works on a single block of data at a time. In the case of standard AES encryption the block is 128 bits or 16 bytes in length. The term “rounds” refers to the way in which the encryption algorithm mixes the data re-encrypting into fourteen times depending on length of key. ENCRYPTION KEYS AES encryption uses a single key as a part of they encryption
examples are given. This paper should have you encrypting in no time. The following commands were done running kernel 2.6.9. .: ENCRYPTING :. I'll outline how to create encrypted containers and drives using the loopback filesystem support and file encryption via openssl. [-=] Containers [=-] This is essentially creating a filesystem within a file and mounting it as a device. Containers vastly decrease the tedious task of individually encrypting files since you simply move your files into the mount
symmetric encryption (also called secret key encryption) and asymmetric encryption (also called public key encryption). Symmetric algorithms are faster, but the main problem associated with this algorithm is key distribution. On the other hand, asymmetric encryption eliminates key security problem, but these algorithms take too much time for encryption and decryption. Certain systems use asymmetric encryption for secure key exchange joined with symmetric algorithms for rapid data encryption. One of
(ASYMMETRIC) ENCRYPTION 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
Encryption 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
Throughout this course many software packages have been discussed as far as their usefulness and application in a computer forensics environment. I have chosen to write about encryption, as well as anti-spyware software. Specifically I will discuss TrueCrypt and Spybot – Search and Destroy. TrueCrypt is a freely available disk encryption package. It is also open-source, which allows independent developers to legally change/modify and/or expand upon the software at their discretion, so long as all applicable
Encryption In the world, where security breaches and information stealing occurs more frequently, a service offering a secure data storage is a significant factor of a security arrangement. Encryption is simply stated as the practice of systematic information scrambling, so that it can be unscrambled later [10]. Data encryption interprets data into a different form, or cryptograph, so that a person holding a secret key (i.e. a decryption key) or password can access that data. The encrypted data is
to provide end to end security of edge nodes. Encryption can be performed using symmetric and asymmetric key cryptography techniques of which symmetric algorithms encrypt and decrypt a message using the same key. If you hold a key, you can exchange messages with peers holding the same key. Several symmetric key algorithms are used among which Blowfish Encryption Algorithm, Data Encryption Standard (DES), 3DES (Triple DES), Advanced Encryption Standard (AES) are major concern of this paper. These
Data Encryption The definition and importance of data encryption 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

Computer security in the early stages mainly focused on the protection of the physical computer. The next major security development was encryption. Computer malware then became common and additional security measures were developed. The Internet prompted the need for network security. The development of cloud storage is the latest technological development that is in desperate need of protection
against data theft is through the implementation of data encryption. And one data encryption product currently available for Windows users, is BitLocker™ BitLocker™ Drive Encryption is a proprietary cryptography tool designed by Microsoft to provide enhanced data protection through The encryption of entire disk drives. This includes the Operating System, user files, system files, swap files and hibernation files. BitLocker provides encryption support for portable hard drives and flash drives aptly
