context: This allows to forge zzâi(xâ) based on zzâ1(xâ,tâ). If z1 outputs are available instead of entire zz1 outputs, the above property still leads to a distinguishing âattackâ requiring about 264 queries. Case 4 : r1 {0, 64} and there exist two distinct values i, j {2, 3, 4,.5} such that ci cj consists of two equal 64-bit halves and ri = rj. The following forgery attack holds in case 4: given a set of 264 (x,t) inputs and the corresponding zz1 and zzi outputs. With a large probability there exist x', ti and x'' blocks such that zzâ1 (xâ,ti) = zzâi(xâ). Let us now replace the ti expanded SQN||AMF sequence by the tj = ti ci cj sequence. It is easy to see, using equation (b), that equality zzâi(xâ,tj) = zzâj(xâ) also holds (in other words, a collision between a zz1 and a zzi value allows to predict a collision between a zz1 value and a zzj value). If z1 outputs are available instead of entire zz1 outputs, the above property still leads to a distinguishing âattackâ requiring about 264 queries.
description: The Access and Mobility Management Function (AMF) manages access and mobility of user equipment (UE) in the 5G core network. It handles user authentication, session management, and connection establishment, enabling smooth transitions of users across network regions.
explanation: AMF is classified as a Network Function because it controls UE access and mobility within the network.
