Is DES symmetric or asymmetric cryptography?
Symmetric
What are the different types of cryptography?
There are 2 types of cryptography such as: 1- Symmetric-key or Secret key Cryptography 2- Asymmetric-key or Public key Cryptography
What is a symmetric encryption?
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
How is cryptography used?
Cryptography is basically the process of hiding information in order to protect the sensitive information, data or message from unknown attacks for any reasons. Cryptography actually consists of two terms encryption and decryption. The process in which message is ciphered or encrypted is known as encryption and the process in which message is deciphered at recipients end is known as decryption. And this whole process is known as cryptography. Public keys and private keys are used in the process of cryptography. Cryptography can be seen as symmetric and asymmetric. In symmetric cryptography same key is used for both encryption and decryption while in asymmetric different keys are used for both encryption and decryption. Today Cryptography is used in various fields like ATM, e-banking, IT security, Maths etc.
What are the Disadvantages of symmetric key cryptography?
Symmetric key cryptography has several disadvantages, primarily the challenge of secure key distribution, as both parties must share the same secret key without interception. Additionally, if the key is compromised, all data encrypted with that key becomes vulnerable. Moreover, managing multiple keys for different users can become complex, as the number of keys increases exponentially with the number of participants. Lastly, symmetric encryption does not provide non-repudiation, making it difficult to prove the origin of a message.
What is a disadvantage of symmetric cryptoghrapy?
Symmetric cryptography only requires one key for both encryption and decryption and therefore in some cases are a issue.
What is a disadvantage of symmetric cryptography?
In symmetric key encryption there is one key that is shared with the person you want to share with your data. The largest disadvantage is that you have to make sure that the key remain secret.
Is DES symmetric or asymmetric cryptography?
Symmetric
What is a common symmetric cryptography solution?
AES
What are the different types of cryptography?

What the the different types of cryptography?

Does symmetric cryptography use the same key to encrypt and decrypt a message?
Yes
How asymmetric cryptography both requires and support the use of symmetric cryptography?
Lmfao - do Richard kays coursework by yourself instead of asking others to answer it for you.
What are the steps involved in symmetric cryptography Also explain key management in conventional cryptography using some example?
following steps are involved in symmetric cryptography 1- sender creates a ciphertext message by encrypting the plain text message with a symmetric encryption algorithm and a shared key. 2- the sender sends the ciphertext message to the recipient. 3- the recipient decrypts the ciphertext message into plain text with a shared key.
What statement relating to access control is accurate?
Symmetric cryptography is impractival when a large group is involved.
What is a symmetric encryption?
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.
What is the two types of cryptography?
Three methods of cryptography are Substitution (substituting one symbol for another), Transposition (rearranging the order of the characters), and Steganography (hiding the existence of the message).
