- Abstract
The fifth-generation (5G) network has attracted extensive attention in both industry and academia in the last few years. Network slicing is an important technique for 5G networks to carry out diversity of networks and applications. In order to ensure the information security in network communication, cryptosystem will be deployed in 5G network slicings, so proposing a secure heterogeneous scheme for communication between different 5G network slicings is necessary, in which different 5G network slicings may use different cryptosystems and cryptographic system parameters. In this article, generic model and security model of heterogeneous signcryption with different system parameters (DSPHS) are defined. We propose two DSPHS schemes between certificateless cryptography (CLC) and public key infrastructure (PKI), and in random oracle model (ROM) we prove that our schemes are secure under the discrete logarithm problem (DLP) and decisional Diffie-Hellman Problem (DDHP). Compared with the existing schemes through performance analysis, our advantages lie in using different cryptographic system parameters in different cryptosystems, requiring less computation cost and energy consumption, satisfying known temporary session key security (KTSKS) and message anonymity.
