2.3 - encryption 🔑 Flashcards
what can encrypting data reduce the risk of?
eavesdropping along data transmission lines
what does plaintext become after it’s gone through an encryption algorithm?
ciphertext
how does symmetric encryption work?
it shifts every single character in a message to something else and requires a single encryption key for both sides of the transmission
what problems could symmetric encryption create?
the number of bits in a binary encryption key may not be able to catch up with technological advances like quantum computers and it can also be really difficult to actually keep the encryption key secret
how does asymmetric encryption tackle the problems associated with its symmetric counterpart?
it generates two matching encryption keys (one public and one private) that’re next-to-impossible to derive from each other
