“…Then, they designed a credible punishment mechanism [12] in rational secret sharing based on the extensive game. By introducing rational communication players, Tian et al [13] proposed a formal framework to solve the problem of interaction among distrusted players. Then, they studied the utility function of rational players, and presented a new rational secret sharing scheme [14] based on Bayesian game.…”

In the rational cryptographic protocol, the two rational players often fall into the prisoner's dilemma, which is also the case for the rational secret sharing we consider in this paper. First, it is proved that rational secret sharing has a sequential equilibrium in the natural state, so that rational participants will fall into the prisoner's dilemma, resulting in no participants being able to reconstruct the secret correctly. Next, to solve this problem, we propose an incentive-compatible rational secret scheme. Specifically, the game tree with imperfect information is constructed to facilitate our analysis and proof, and the strictly dominated strategies are directly eliminated to simplify the game tree. Further more, we describe the motivation of the verifier. Then, we prove that rational players have no motivation to deviate from honest behavior using sequential equilibrium so that rational players can reconstruct the secret correctly. Finally, we complete the simulation using the smart contract and analyze our entire scheme. In addition, the game of our scheme does not need to be repeated multiple times to reach sequential equilibrium, i.e., the game always follows the rational path.

“…Then, in standard communication networks, they presented information-theoretic secure rational secret sharing scheme [14]. Tian et al [15] reviewed the classical secure communication issues, which are always described as a set of interactive rules following a specified sequence in the perspective of game theory. By introducing rational communication participants, they model the secure communication process in the manner of game theory to capture the interactions of distrusted communication parties.…”

“…However, with making greater progress of Internet and hardware facilities, people feel desirable for higher bandwidth services. Unicast or broadcast doesn't seem to produce remarkable economic efficiencies which can achieve the development of multicasting [3,[9][10][11]18]. By means of multicasting, one source of sender can transmit the data to many receivers, abating not only the burden of network but also the loading of transmitters, and thereby we contribute a great number of advantages to this multicasting model.…”

In this paper, we have adopted elliptic curve multiplication operation, ID-based character in bilinear pairing, one-way hash function, and time access control to construct a time-bound hierarchical access control and key management scheme for multicast systems. In this scheme, central authority distributes a group key for every security class (SC) and a time-bound secret key for each member of security class. With its time-bound secret key, each member in SC can obtain a group key to decrypt the message and thereof utilize the group key to attain the group keys for successors so as to decrypt their data sets. Considering many common ways of dynamic access control, namely, a new member joining in the security class, an existing member departing from a security class, replacing timebound key, increasing security class, decreasing security class, replacing group key, adding relationship and deleting relationship among SCs, all of them are explicitly discussed in this paper. In view of the security and performance analyses under many typical attacks, we thereby prove our proposed scheme can prevent malicious attacks effectively with less computation time and more reasonable complexity. In consequence, the proposed scheme offers a secure and hierarchical access control in multicast systems.
