Symmetric encryption involves what key?
A shared secret keyand other words;Both the sender and receiver share the same key
How does the encryption process work with a 48-bit key?
Encryption with a 48-bit key involves using a specific algorithm to scramble the data into a code that can only be deciphered with the correct key. The key, which is 48 bits long, determines how the data is encrypted and decrypted. The longer the key, the more secure the encryption, as there are more possible combinations to crack.
What does it mean to hash data and why is it important in data security and encryption?
Hashing data involves converting input data into a fixed-size string of characters using a mathematical algorithm. This process is important in data security and encryption because it helps ensure the integrity and authenticity of the data. Hashing makes it difficult for attackers to tamper with or manipulate the data, as even a small change in the input data will result in a completely different hash value. This makes it easier to detect any unauthorized changes to the data and helps protect sensitive information from being accessed by unauthorized parties.
How does hashing work in computer science and what are its applications in data security and encryption?
Hashing in computer science involves taking input data and generating a fixed-size string of characters, known as a hash value, using a specific algorithm. This hash value is unique to the input data and is used for various purposes, including data security and encryption. In data security, hashing is used to verify the integrity of data by comparing hash values before and after transmission or storage. If the hash values match, it indicates that the data has not been tampered with. Hashing is also used in password storage, where passwords are hashed before being stored in a database to protect them from unauthorized access. In encryption, hashing is used to securely store sensitive information, such as credit card numbers or personal data. Hashing algorithms are also used in digital signatures to verify the authenticity of a message or document. Overall, hashing plays a crucial role in data security and encryption by providing a way to securely store and verify data integrity.
How does data encryption help keep data secure?
When data is stored or sent, it can be sent as it is, when over a network this would be packets. But when data is encrypted, its simply like saying, if i sent you an email that says Hi, How are you H = 103343 i = 408300 , = 985742 The numbers are sent not the letters so the computer on the other end, Decrypts this data for your display.
Does asymmetric encryption involves keys?
Symmetric encryption requires one key known by both parties. Asymmetric encryption uses two keys, one encryption key known publicly and one decryption key known only by the recipient.Or more simply put,YesA public and private key
What is the meaning of asymmetric encryption?
Asymmetric Encryption is a form of Encryption where keys come in pairs. What one key encrypts, only the other can decrypt. Frequently (but not necessarily), the keys are interchangeable, in the sense that if key A encrypts a message, then B can decrypt it, and if key B encrypts a message, then key A can decrypt it. While common, this property is not essential to asymmetric encryption. Asymmetric Encryption is also known as Public Key Cryptography, since users typically create a matching key pair, and make one public while keeping the other secret. Users can "sign" messages by encrypting them with their private keys. This is effective since any message recipient can verify that the user's public key can decrypt the message, and thus prove that the user's secret key was used to encrypt it. If the user's secret key is, in fact, secret, then it follows that the user, and not some impostor, really sent the message. Users can send secret messages by encrypting a message with the recipient's public key. In this case, only the intended recipient can decrypt the message, since only that user should have access to the required secret key. The key to successful use of Asymmetric Encryption is a Key Management system, which implements a Public Key Infrastructure. Without this, it is difficult to establish the reliability of public keys, or even to conveniently find suitable ones.
Symmetric encryption involves?

What is the difference between synchronous and asynchronous cryptography?
in synchronous communication data will be transmitted with clock and in asynchronous only start and stop bit is required for transmission of databut speed of the data transmission in synchronous is very high data rateand in asynchronous speed is slow due to the start and stop bit
Symmetric encryption involves what key?
A shared secret keyand other words;Both the sender and receiver share the same key
What does the word encrypted mean?
The word encryption is the noun form of the word encoding. It is the process of converting information or data into code. Encryption also involves password-protecting something.
What is asymmetric synthesis?
When a compound containing an asymmetric carbon atom is synthesised by ordinary laboratory methods from a symmetric compound ,the product is a racemic mixture.if ,however ,such a synthesis is carried under the asymmetric influence of a suitable optically active reagent ,only one of the optically active isomers ( or-)is formed.This process in which an asymmetric compound is synthesised from a symmetric compound to yield the ( ) isomer or (-)isomer directly is termed asymmetric synthesis.
What is a product cipher?
A product cipher is a type of encryption that combines multiple simple encryption techniques to enhance security. It typically involves two or more rounds of substitutions and permutations, where each round applies a different cipher method. This layering process makes it significantly more difficult for attackers to break the encryption compared to using a single cipher. Examples of product ciphers include the Data Encryption Standard (DES) and the Advanced Encryption Standard (AES).
What are 3 types of mitosis?
The three types of mitosis are symmetric, asymmetric, and open. Symmetric mitosis results in two daughter cells with similar properties, while asymmetric mitosis generates daughter cells with different fates. Open mitosis involves the breakdown of the nuclear envelope during cell division.
What are normal modes of vibrations in case of carbonate ion?
In the case of the carbonate ion (CO3^2-), there are three normal modes of vibration associated with its symmetric stretching, asymmetric stretching, and bending motions. The symmetric stretching mode involves all three oxygen atoms moving in the same direction simultaneously, while the asymmetric stretching involves the two shorter C-O bonds stretching at different rates. The bending motion involves the distortion of the linear O-C-O angle.
