“…This scheme is considered useful with devices that have limited resources because the characteristics of confidentiality, authentication, integrity, and non-repudiation can be produced concurrently by the minimam cost [14]. The major feature of the signcryption is that the signature and encryption have been combined at the single logical step [15], [16], [17], which reduces the computational cost. However, all of the above-mentioned schemes are not suitable for the IoV scenario, because the limitation resource in the sensors embedded in the vehicles.…”

With the widespread of the vehicular ad-hoc network (VANET), a huge number of vehicles are connecting to networks. To provide the position of these vehicles, the global position system (GPS) is required. Usually, the GPS is commoned with internal sensors mounted inside the vehicle. Thus, the communication with this sensor is needed when we need to specify the position of vehicle through the satellite. This communication is done by using a secure channels. However, the authentication and privacy are deemed as the main goal of the network communication. Therefore, an efficient signcryption scheme for vehicular satellite-based network (SVSN) is proposed in this paper. The proposed scheme meets the security demands for VANETs, for instance authentication, unforgeability, confidentiality, and integrity. Based on the Discrete Logarithm (DL) problem, the presented scheme is secure. Compared with the existing signcryption schemes, the performance analysis show that our proposed scheme is more suitable for vehicular satellite networks.

“…For the scheme [11], every subscriber obtains the same session key from the broadcaster, if one of the subscribers wants to unregister from the broadcaster, the broadcaster needs to re-change and redistribute the session key for the other subscribers. Recently, [14] and [15] proposed an efficient identitybased broadcast signcryption scheme respectively, their schemes have constant size ciphertext for the broadcaster, but the broadcaster needs to transmit the identity information of designated receivers, and the public key generated and delivered by the PKG is of size linear in the maximal value of the set of receivers, for the receiver IDi the cost of multiplication and exponentiation operations depends on number of receivers, that computation overheads is too high for a user, thus their schemes do not apply to the end user with limited computing capability. Moreover, the schemes all above do not satisfy the register secrecy and forward secrecy security attributes.…”

Broadcast signcryption, which enables the broadcaster to simultaneously encrypt and sign the content meant for a specific set of users in a single logical step, provides the most efficient solution to this dual problem of confidentiality and authentication. Recently, several identity-based broadcast signcryption (IBBSC) schemes have been proposed. However, we find almost all IBBSC schemes that have been proposed until now do not satisfy register secrecy and forward secrecy. Following this, we propose a new IBBSC scheme and formally prove its security under the random oracle model for broadcast signcryption (IND-CCA2 and EUF-CMA) While we propose a secure IBBSC scheme, we do not compromise the performance. The proposed scheme only requires two pairing operations for end user devices with limited computing capability
