Abstract
【選択図】図1
Description
T=HAMC−Hash(K,M)
P_Hash(Z,シード)=HAMC−Hash(Z,A(1)‖シード)‖HMAC−Hash(Z,A(2)‖シード)‖HMAC−Hash(Z,A(3)‖シード)...
ここで‖は、連接を表わし、A()は下記のように定義される。
A(0)=シード;A(j)=HMAC_Hash(Z,A(j−1))
PRF(Z,ラベル,シード)=P_MD5(S1,ラベル‖シード)+P_SHA−1(S2,ラベル‖シード)
ここで、通常のように、+は、排他的論理和を表わし、‖は、連接を表わす。値S1とS2はオクテットストリング秘密Zを半々に分割することで得られ、左半分は、S1であり右半分は、S2であり、左半分が大きく、秘密は奇数個のオクテットを有する。
SHA−1(X+Z‖Y)
