Kim Thuat Nguyen, Nouha Oualha, Maryline Laurent. Lightweight certificateless and provably-secure signcryptosystem for the internet of things. Abstract-In this paper, we propose an elliptic curve-based signcryption scheme derived from the standardized signature KCDSA (Korean Certificate-based Digital Signature Algorithm) in the context of the Internet of Things. Our solution has several advantages. First, the scheme is provably secure in the random oracle model. Second, it provides the following security properties: outsider/insider confidentiality and unforgeability; non-repudiation and public verifiability, while being efficient in terms of communication and computation costs. Third, the scheme offers the certificateless feature, so certificates are not needed to verify the user's public keys. For illustration, we conducted experimental evaluation based on a sensor Wismote platform and compared the performance of the proposed scheme to concurrent schemes.
In REF , we have proposed a new signcryption scheme based on ECKCDSA, and we have formally proven the security of this scheme in the random oracle model, thus providing outsider/insider confidentiality and unforgeability, in addition to non-repudiation, while being more efficient in terms of communication and computation costs than existing signcryption schemes.
