Fields

ak: Option<[u8; 6]>

AK is a 48-bit anonymity key that is the output of either of the functions f5.

ck: Option<[u8; 16]>

CK is a 128-bit confidentiality key that is the output of the function f3.

ik: Option<[u8; 16]>

IK is a 128-bit integrity key that is the output of the function f4.

k: [u8; 16]

K is a 128-bit subscriber key that is an input to the functions f1, f1*, f2, f3, f4, f5 and f5*.

maca: Option<[u8; 8]>

MACA is a 64-bit network authentication code that is the output of the function f1.

macs: Option<[u8; 8]>

MACS is a 64-bit resynchronisation authentication code that is the output of the function f1*.

op: Option<[u8; 16]>

OP is a 128-bit Operator Variant Algorithm Configuration Field that is a component of the functions f1, f1*, f2, f3, f4, f5 and f5*.

opc: [u8; 16]

OPc is a 128-bit value derived from OP and K and used within the computation of the functions.

res: Option<[u8; 8]>

RES is a 64-bit signed response that is the output of the function f2.

res_star: Option<[u8; 16]>

RES* is a 128-bit response that is used in 5G.

Implementations

impl Milenage

pub fn new_with_op(k: [u8; 16], op: [u8; 16]) -> Milenage

Returns a new initialized Milenage from K and OP

pub fn new_with_opc(k: [u8; 16], opc: [u8; 16]) -> Milenage

Returns a new initialized Milenage from K and OPc

pub fn f1(&mut self, rand: &[u8; 16], sqn: &[u8; 6], amf: &[u8; 2]) -> [u8; 8]

F1 is the network authentication function. F1 computes network authentication code MAC-A from key K, random challenge RAND, sequence number SQN and authentication management field AMF.

pub fn f1star( &mut self, rand: &[u8; 16], sqn: &[u8; 6], amf: &[u8; 2] ) -> [u8; 8]

F1Star is the re-synchronisation message authentication function. F1Star computes resynch authentication code MAC-S from key K, random challenge RAND, sequence number SQN and authentication management field AMF.

pub fn f2345( &mut self, rand: &[u8; 16] ) -> ([u8; 8], [u8; 16], [u8; 16], [u8; 6])

F2345 takes key K and random challenge RAND, and returns response RES, confidentiality key CK, integrity key IK and anonymity key AK.

pub fn f5star(&mut self, rand: &[u8; 16]) -> [u8; 6]

F5Star is the anonymity key derivation function for the re-synchronisation message. F5Star takes key K and random challenge RAND, and returns resynch anonymity key AK.

pub fn compute_res_star( &mut self, mcc: &str, mnc: &str, rand: &[u8; 16], res: &[u8; 8] ) -> Result<[u8; 16], String>

Computes RESStar from serving network name, RAND and RES as described in A.4 RES* and XRES* derivation function, TS 33.501.

impl Default for Milenage

fn default() -> Milenage

Returns the “default value” for a type.
