APE：經過身份驗證的基於排列的加密如何工作？

我正在嘗試了解 APE 的加密和解密過程： APE: Authenticated Permutation-Based Encryption for Lightweight Cryptography

全文

加密

Vc這里和這裡到底是什麼Vr？範例而不是 permutation p，如果我決定用分組密碼替換它怎麼辦？Vc 會成為分組密碼的密鑰嗎？那麼明文Vr會是什麼？xor'ed

一個簡單的人類可讀的虛擬碼將很有幫助。我開始嘗試重寫虛擬碼，但有很多未解決的問題。

[CipherText, Tag] function Encrypt(Key, A, Plaintext):
begin
 u = len(A)
 w = total number of blocks in the plaintext// eg. 1 block 64 bit block size
 V = [0,....K]
 if(A not zero) then
   A = {A[1] .... A[u]}
    for i = 1 to u do
        V = p(A[i] xor Vr, Vc) // can replace this with block cipher eg bcp(plaintext,key)
    end
 endif

 V = V xor [0,1] // What is (0,1)?
 M = {Plaintext[1],.......Plaintext[w]} // devide into blocks eg. 64 bits each.
 for i = 1 to w do
    V = p(M[i] xor Vr, Vc) // what is the Vr and Vc here?
    C[i] = Vr
 end

CipherText = {C[1],.......C[w]} 
Tag = Vc Xor Key // what is the Vc here from?
end
