Step 2\+: res = xdout

Suggested length for res is 128 bits, i.\+e. 16 bytes, but also can be in range\+: 30 $<$ n $<$ 128 bits.

3GPP TS 33.\+102, clause 6.\+8.\+1.\+2, b sres = c2(res) = res[0-\/3] $^\wedge$ res[4-\/7] $^\wedge$ res[8-\/11] $^\wedge$ res[12-\/15]

3GPP TS 33.\+102, clause 6.\+8.\+1.\+2, c kc = c3(ck, ik) = ck[0-\/7] $^\wedge$ ck[8-\/15] $^\wedge$ ik[0-\/7] $^\wedge$ ik[8-\/15] FIXME\+: do we really have CK/\+IK for GSM?

Step 3\+: cdout = sqn[0-\/5] $\vert$$\vert$ amf[0-\/1] NOTE (for USIM)\+: sqn[0-\/5] = autn[0-\/5] $^\wedge$ ak[0-\/5]

Step 5\+: autn = sqn $^\wedge$ ak $\vert$$\vert$ amf $\vert$$\vert$ mac NOTE\+: cdout still contains SQN from step 3
