还有一些参数的基本概念和构成如下:
AK a 48-bit anonymity key that is the output of either of the functions f5 and f5*.
AMF a 16-bit authentication management field that is an input to the functions f1 and f1*.
c1,c2,c3,c4,c5 128-bit constants, which are XORed onto intermediate variables.
CK a 128-bit confidentiality key that is the output of the function f3.
IK a 128-bit integrity key that is the output of the function f4.
IN1 a 128-bit value constructed from SQN and AMF and used in the computation of the functions f1 and f1*.
K a 128-bit subscriber key that is an input to the functions f1, f1*, f2, f3, f4, f5 and f5*.
MAC-A a 64-bit network authentication code that is the output of the function f1.
MAC-S a 64-bit resynchronisation authentication code that is the output of the function f1*.
OP a 128-bit Operator Variant Algorithm Configuration Field that is a component of the functions f1, f1*, f2, f3, f4, f5 and f5*.
OPC a 128-bit value derived from OP and K and used within the computation of the functions.
OUT1,OUT2,OUT3,OUT4,OUT5
128-bit computed values from which the outputs of the functions f1, f1*, f2, f3, f4, f5 and f5* are obtained.
r1,r2,r3,r4,r5 integers in the range 0–127 inclusive, which define amounts by which intermediate variables are cyclically rotated.
RAND a 128-bit random challenge that is an input to the functions f1, f1*, f2, f3, f4, f5 and f5*.
RES a 64-bit signed response that is the output of the function f2.
SQN a 48-bit sequence number that is an input to either of the functions f1 and f1*. (For f1* this input is more precisely called SQNMS.)
TEMP a 128-bit value used within the computation of the functions.
