Session key reusability using 3-PAKE in symmetric key cryptography

In symmetric key cryptography, there exists an issue of secure exchange of keys over the insecure network. Threats occur due to presence of adversary in the network or due to infiltration of personal security. The problem of network security is addressed by LHX-3PAKE protocol as it is proved to be free from various well-known attacks. But this protocol also poses a disadvantage of numerous complex and time-consuming modular exponential calculations. As the problem of network security is already taken into account by LHX-3PAKE, only the problem of personal security persists. If this issue can be solved, the session key can be reused, thus making the whole process of key establishment faster.
