An efficient and practical threshold gateway-oriented password-authenticated key exchange protocol in the standard model

Gateway‐oriented two‐server password authenticated key exchange protocol for unmanned aerial vehicles in mobile edge computing

“…The first type is gateway‐oriented password protocol, in which a gateway is deployed in the middle of the mobile user and the server such that the adversary cannot directly get access to the server. The gateway can be viewed as a fire wall [9]. However, the attacker still can compromise the server if it can bypass the gateway.…”

“…The robustness of the system is not satisfactory. The last type is the threshold password protocols [9]. The password is split to n shares and stored in n different servers, respectively.…”

Fully distributed certificateless threshold signature without random oracles

“…Moreover, we give the first concrete fully distributed CLTS scheme by employing verifiable secret sharing [2] and distributed key generation (DKG) [3]. The security of the proposed scheme can be proven under the standard model like in [4,5].…”
