The message to be stored in the database is converted to cipher text using encryption algorithm and key. The resulting cipher text is then saved in database. When the user needs to get the actual message, he/she decrypts the cipher text with decryption algorithm and the key [3]. Random keys are generated in encryption process and same keys are used to decrypt the data. The security solely depends on the choice of encryption algorithm, key size and how the algorithm is implemented. If any of these criteria goes wrong, it can cause adverse effects in the security of data.
There are different ways by which encryption can be achieved, Encryption by means of algorithms and through Hashing. Different encryptions based on algorithms and key are DES, RC2, AES_128, AES_256 etc [13]. Hashing is the process in which the message is converted to hash value using hash function. For example, the password entered by user is encrypted to hash key value and it is compared with the encrypted password stored in the database. If the result varies, then an invalid username/password is entered. Hash functions commonly in use are MD4, MD5, SHA, SHA-1[13].
5.1.2.1 Notations used for Encryption scheme
Key is an important requirement in encryption process.pk is denoted as public key and sk as private key [5]. Encryption process is denoted by Enc and decryption process is denoted by Dec. Given a plaintext m and key k, encryption is defined as Enc (m, k) and Decryption is defined as
Encryption technique is the translation of data into a secret code that will prevent hackers or identity thieves from being able to break or read the data that is sent across the network.
In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into
The security I use a database management program such as PHPMyAdmin (with the WEE extension), select the field you need to encrypt by its name from a menu, select the public key and press the encrypt button, the protected information is ready to be stored in the database.
Encryption is the conversion of electronic data into another form, called cipher text, which cannot be easily understood by anyone except authorized parties. The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted via the Internet or other computer networks. Modern encryption algorithms play
Moreover, encryption requires use of a key or cipher, which is used to lock and unlock the hidden data. Such a key is necessary to allow the hidden data to be viewed in an intelligible manner by those who are authorized to view it. However, there is always a risk that the encryption key might fall into the wrong hands, thereby allowing the information to be accessed by unauthorized viewers.
Data, often referred to as plaintext, is encrypted using an encryption algorithm and an encryption key. This process generates ciphertext that can only be viewed in its original form if decrypted with the correct key. Decryption is simply the inverse of encryption, following the same steps but reversing the order in which the keys are applied (Rouse, 2014).
Encryption is a method of encoding a message or information before sending it, so unauthorized users can’t access it without permission and only the person who has authorised access to it can decode it. Encryption is used to keep things secure and keep things confidential within the organisation. For example let’s say you have a chat with a friend on Skype, when you’re sending a message to him, that message will display as random symbols until he receives it, which then decodes it and makes it so that only he can read it. This allows the communication to be secure and private, no one will be able to know what the message says.
An encryption algorithm takes the original message and encodes it using the encryption key and creates an encrypted message. The only way to retrieve the original message is by decrypting the message using the encryption key. If the encryption key uses a 128-bit key is the same as saying that there are 128² possible key combinations. Algorithms are classified
To understand encryption, you must place yourself into the internet of the 90’s. At the time the internet was still new, all the data could be seen and accessed easily.The problem was that anyone could access your information and read it. This was a major issue because at that time, internet privacy was almost impossible.
Encryption is a process of converting Plain text into Cipher text. This un-readable message can be communicated over an unsecure network without the fear of loss of integrity and confidentiality. Encryption process is done using encryption algorithm.
Database Encryption is one of the technique used for securing the data in database. This method transforms information on a computer in such a way that it becomes unreadable. So, even if someone is able to gain access to a computer with personal data on it, they likely won’t be able to do anything with the data unless they have original data key, complicated or expensive software. The main function of encryption is essentially to translate normal text into cipher text. Encryption makes sure that data doesn’t get read by the wrong people, but can also ensure that data isn’t altered in transit, and verify the identity of the sender. Data Encryption method typically uses a specified parameter or key to perform the data transformation. Some encryption algorithms require the key to be the same length as the message to be encoded, yet other encryption algorithms can operate on much smaller keys relative to the message. Encryption is most used among transactions over insecure channels of communication, such as the internet. Encryption is also used to protect data being transferred between devices such as mobile telephones, automatic teller machines (ATMs), and many more. Encryption can be used to create digital signatures, which allow a message to be authenticated. When properly implemented, a digital signature gives the recipient of a message reason to believe the message was sent by the claimed sender.
Encryption is a cryptography in which one covers data or information by transforming it into an undecipherable code. Encryption generally uses a predefined parameter or key to perform the data change. Some encryption computations oblige the best approach to be the same length as the message to be encoded yet other encryption counts can take a shot at much more diminutive keys concerning the message. Separating is as often as possible described close by encryption as it’s backwards. Unscrambling of encoded data realizes the first data. Encryption is used as a piece of customary forefront life. Encryption is most used among trades over flimsy channels of correspondence for instance the web. Encryption is also used to secure data being traded between contraptions, for instance, modified teller machines (ATMs), cells, and various more. Encryption can be used to make automated imprints, which allow a message to be affirmed. Exactly when honest to goodness executed, an automated imprint gives the recipient of a message inspiration to acknowledge the message was sent by the affirmed sender. Modernized imprints are outstandingly significant when sending tricky email and distinctive sorts of cutting edge correspondence. This is by and large equivalent to standard composed by hand marks, in that, an all the more astounding imprint passes on a more multifaceted methodology for manufacture. Figure a figure is an estimation, strategy, or method for performing encryption and translating.
Encryption is a method of programming data for security so that it appears to be random data. Only the people sending and receiving the information have the key to decrypt the message, which will put it back into its original form making it readable. The only people with the key are the people who are intended to read the message. Not many people know what encryption is. I took a survey of twenty students and asked two questions. The first question I asked was do you know what encryption means and the second question I asked was have you ever heard of anybody using encryption. This is a chart of the information I received:
Asymmetric key system (or asymmetric algorithm; public key): A cryptographic system that uses two separate keys: one key to encrypt and a different key to decrypt information. These keys are known as public and private
