Internet of Things (IoTs) is an enabler for the intelligence appended to many central features of the modern world, such as hospitals, cities, grids, organizations, and buildings. The security and privacy are some of the major issues that prevent the wide adoption of IoTs. Its storage and computing power of these devices is often limited and their designs currently focus on ensuring functionality...
In recent years, LTE (Long Term Evolution) has been one of the mainstreams of current wireless communication systems. But when its HSS authenticates UEs, the random number RAND generated by HSS for creating other keys during its delivery from HSS to UE is unencrypted. Also, many parameters are generated by invoking a function with only one input key, thus very easily to be cracked. So in this paper,...
In a wireless system, the L2 and L3 often have their own individual security mechanisms used to authenticate users and system entities, and protect delivered keys and messages. When a mobile device hands over from one BS to another, the handover latency is usually one of the key factors affecting wireless service QoS. However, a strict security scheme often requires a longer handover delay. Also,...
