Symmetric vs Asymmetric Flashcards
What is symmetric encryption?
It uses one key to encrypt information and decrypt information
What are the consideration for symmetric encryption?
Its faster, but since it only has one key if a attacker get a hold of that key they have access to al the data
What is AES encryption?
It uses symmetric encryption, the strongest, it uses block cipher, has 128bit,192 bit, and 256 bit variations
What is DES and 3DES?
It uses symmetric encryption, its weak, uses block cipher, and has 56 bit, 112 bit, and 168 bit
What is blowfish?
It uses symmtetric encryption, uses block cipher, weak, has 64 bit version
What is Rivest Cipher?
It uses symmetric encryption, stream cipher, and Rc5/rc6 on block cipher
What is asymmetric encryption?
it uses one key the public key to encrypt information and uses a private key to decrypt information
What is RSA encryption?
It is asymmetric encrption, one of the oldest. stands for Rivest, Shamir, Adleman
What is Diffie-Hellman?
Old standard with many variants, one of the first, uses asymmetric encryption
What is DSA algorithm?
It is endorsed by the NIST for the digital signature standard and uses asymmetric encryption
What is EIGamal?
It is used in GNU privacy guards, and pretty good privacy. Uses pretty good privacy and asymmetric encryption
What is a digital signature
It is where you create a hash value using a hashing algorithm and then encrypt it using one of your keys
