The 5G network takes advantage of the small cells technology. The next logical step is to cover the urban landscape with mobile small cells, to optimize network services. However, the introduction of mobile small cells raises various security challenges. Cryptographic solutions are capable of solving these as long as they are supported by appropriate key management schemes. The threshold-tolerant identity-based cryptosystem, forms a solid basis for key management schemes for mobile small cells. However, this approach is unable to sustain security over time. Therefore, we introduce two extensions, proactive secret sharing and private key cloaking, to address this challenge.
