Webthe public-key setting. We refer to this primitive as signcryption, adapting the terminology of [35]. We present two de£nitions for the security of signcryption depending on whether the adversary is an outsider or a legal user of the system. We then examine generic sequential composition methods of building signcryp- WebEquipped with the advantages of flexible access control and fine-grained authentication, attribute based signcryption is diffusely designed for security preservation in many scenarios. However, realizing efficient key evolution and reducing the calculation costs are two challenges which should be given full consideration in attribute based cryptosystem. WebAlso, the system is very fast, as both encryption and decryption procedures have a low complexity. Therefore, this paper studied code-based signcryption scheme, and combined McEliece encryption scheme with slightly modified versions of Xinmei signature scheme, then proposed a signcryption scheme based on McEliece public-key cryptography. polywic silver
