Cryptography
1.SKC (Symmetric Key Cryptography)
[type]
Common type:
DEA (Data Encryption Standard)
AES (Advanced Encryption Standard)
DEA (Data Encryption Standard)
AES (Advanced Encryption Standard)
[Introduction]
Same Key between encryption and decryption.
[Pro]
Faster
[Con]
Can not be used in EMR.
[source]2.PKC(Public Key Cryptography)
[alias]AKC(Asysmmetric Key Cryptography)
[type]
common type:
RSA(Rivest-Shamir-Adleman encryption)
ElGamal(ElGamal cryptography)
ECDSA
Rabin
[introduction]
opposite of SKCproduces different ciphertext with same key and plaintext
every person have their own public key and private key.
[Pro]
safer
[Con]
more poeple have, more public key and private key requires.
It takes lots of memory when there are lots of poeple.
Can not be used in EMR.

3.ABE(Attribute-Based Encryption)
[introduction]
It can exactly control the acesses of the data.
Only person who meets the requirements of ABE can decryption the cipher text.
If person who does not meet the requirements of ABE, one can not understand the meaning of the cipher text.
[Pro]
Can be used in EMR.
[Cons]
more complex than others.
