Asymmetric cryptography, also known as public-key cryptography, involves a pair of keys: a public key, which can be shared openly, and a private key, which is kept secret. This method allows for secure communication and data exchange, as the public key encrypts messages that can only be decrypted by the corresponding private key. Key characteristics include enhanced security, as the private key is never shared, and the ability to authenticate identities through digital signatures. This system is widely used in secure communications, such as SSL/TLS for internet security.

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
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 is cipher in cryptography?
Encryption and decryption algorithms are called ciphers in cryptography
What encryption does a smart card use?
Smart cards typically use a combination of symmetric and asymmetric encryption. Common algorithms include AES (Advanced Encryption Standard) for symmetric encryption and RSA or ECC (Elliptic Curve Cryptography) for asymmetric encryption. These encryption methods help secure the data stored on the card and facilitate secure communication between the card and external systems. Additionally, smart cards often implement secure key management practices to protect sensitive cryptographic keys.

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 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).
What kind of cryptography?
Cryptography can be broadly categorized into symmetric and asymmetric cryptography. Symmetric cryptography uses the same key for both encryption and decryption, making it fast but requiring secure key distribution. Asymmetric cryptography, on the other hand, employs a pair of keys: a public key for encryption and a private key for decryption, enhancing security but typically being slower. Additionally, there are other forms like hash functions and digital signatures, each serving specific purposes in securing data and communications.

What are characteristics of public key cryptography?
If data is encrypted with public key, only private key can decrypt it. AGN
Difference between symmetric and asymmetric key cryptography?
Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric. If you do a quick search on the differences between symmetric and asymmetric you can find many more explanations. This just a quick overview.
