Cryptography & Encryption Flashcards
This is the process of converting plaintext into ciphertext (the original message into encoded, unreadable messages)
Encryption
The uncoded, original message that is to be encrypted
Plaintext
The Algorithm used to perform the encryption and decryption
Cipher
What type of encryption ciphers are there?
Symmetric Encryption
Asymmetric Encryption
The same key is used for both encryption and decryption
Symmetric encryption
Different keys are used for encryption, (public key), and decryption (private)
Asymmetric Encryption
_______ is the science of protecting information by transforming it into secure format
Cryptography
The encrypted message is called
Ciphertext
Is encryption reversible
Yes
Homomorphic
Allows data to be processed while still encrypted, keeping it private, even during operations
Steganography
Hides messages within other data, like images or audio, making them nearly undetectable unless you know how to find them.
Useful for secret communication
A combination of encryption algorithms used to secure a network connection
Cipher suite
______ encrypts data one bit or byte at a time
Stream ciphers
_____ except data in fixed size chunks
Block ciphers
An innovative use of cryptographic principles, creating a secure and immutable ledger of transactions
Blockchain
AES
Advanced Encryption Standard
