Advantages and disadvantages of encryption and decryption
Answers
Answer:
1. Encryption Provides Security for Data at All Times
Generally, data is most vulnerable when it is being moved from one location to another. Encryption works during data transport or at rest, making it an ideal solution no matter where data is stored or how it is used. Encryption should be standard for all data stored at all times, regardless of whether or not it is deemed “important”.
2. Encrypted Data Maintains Integrity
Hackers don’t just steal information, they also can benefit from altering data to commit fraud. While it is possible for skilled individuals to alter encrypted data, recipients of the data will be able to detect the corruption, which allows for a quick response to the cyber-attack.
3. Encryption Protects Privacy
Encryption is used to protect sensitive data, including personal information for individuals. This helps to ensure anonymity and privacy, reducing opportunities for surveillance by both criminals and government agencies. Encryption technology is so powerful that some governments are attempting to put limits on the effectiveness of encryption—which does not ensure privacy for companies or individuals.
4. Encryption is Part of Compliance
Many industries have strict compliance requirements to help protect those whose personal information is stored by organizations. HIPAA, FIPS, and other regulations rely on security methods such as encryption to protect data, and businesses can use encryption to achieve comprehensive security.
Answer:
Encryption :Data encryption is the process of converting data into a different form.
Decryption :When data is received, decryption is the process of converting it from ciphertext to plaintext.
Explanation:
Encryption :
Data encryption is the process of converting data into a different form or code so that only those with the correct decryption key can access it (or password). Encrypted data, also known as ciphertext, is one of the most common and widely used types of data security. Even if you have a data breach involving ciphertext, the attackers will not be able to see the information.
Data Encryption Types:
The term "asymmetric encryption" refers to the fact that keys come in pairs. This means you have two keys, one of which encrypts and the other of which decrypts. The keys are frequently interchangeable, but this is not always true.
1. Encryption is a low-cost solution.
Encryption technology is built into almost every device and operating system we use today. Microsoft Windows, for example, includes a program called BitLocker that can encrypt entire volumes on your hard drive.
2. Regulatory Fines Can Be Avoided With Encryption
Although there are no explicit requirements for encrypting data in regulations such as the GDPR, "security measures and safeguards" must be implemented to protect the privacy of data subjects – assuming they are EU citizens. HIPAA (Health Insurance Portability and Accountability Act of 1996), for example, requires that confidential information be encrypted. As a result, if a portable device or drive containing unencrypted ePHI is misplaced or stolen, the organization faces serious consequences.
Decryption:
When data is received, decryption is the process of converting it from ciphertext to plaintext. The recipient can either manually decrypt the ciphertext to its readable version or use the same key that encrypted the data once the data has been safely received. Data and information are meaningless without decryption.
If a vendor receives an email from a client with a document detailing the requirements for their latest project, this is an example of decryption. Although the details appear in plain text when they open the email, their system decrypted the data upon receipt. The ciphertext was unreadable while travelling over the network, protecting the intellectual property of the two companies.
Computers use keys to figure out which characters in an encrypted message represent other characters. An algorithm could, for example, convert each letter in the alphabet to the next letter in the alphabet.
Symmetric: A symmetric algorithm key encrypts and decrypts data using the same secret key. The data is encrypted by the original device, which sends the key along with the file for the receiving device to decrypt.
When asymmetric keys are used, they create a public key and a secret key, which increases security. when a message is encrypted by a device The public key is accessible to anyone in the world, but only the message's recipient has access to the secret, or private key.
1. Public: keys are large numbers or codes that encrypt data and are available to the public. Encryption creates two pairs of keys, public and private, for the sender and recipient of a secure message in public-key cryptography.
2. Private: Users can decrypt messages using private keys, which travel with public keys.
3. Preshared: PSKs, or preshared keys, are keys that two devices send to each other before encrypting data. These are secret keys that are sent through secure channels by two people.
