AES

 AES [abbr] Advanced encrytion standard [step] (1)make a state (4*4 matrix table) (2)AddRoundKey operation of XOR bewteen round key and the value of every elements in plain text. (3)subbytes S-box conversion. (4)shiftrows shift left with k for every row where k is constant.  (5)MixColumns GF for every rows. coefficient of GF formula is x^0, x^1,x^2,x^3, respectively. e.g. A[0,0]->x^0,A[0,1]->x^1,A[1,0]->x^0 source: AES 加密演算法的原理詳解_FKNIGHT 的博客-CSDN博客_aes演算法 https://zh.wikipedia.org/zh-tw/高级加密标准

 Cryptography 1.SKC (Symmetric Key Cryptography) [type] Common type: 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] Always Encrypted: Deterministic vs. Randomized (azureblue.io) 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 SKC produces 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. [source] Always Encrypted: Deterministic vs. Randomized (azureblue.io) 公開金鑰加密 - 維基百科，自由的百科全書 (wikipedia.org) 3.ABE(Attribute-Based Encryption) [introduction] It can exactly control the acesses of the data.
