摘　　要：Network coding can improve the information transmission efficiency and reduces the network resource consumption,so it is a very good platform for information transmission.Certificateless proxy signatures are widely applied in information security fields.However,certificateless proxy signatures based on classical number theory are not suitable for the network coding environment and cannot resist the quantum computing attacks.In view of this,we construct certificateless network coding proxy signatures from lattice(LCL-NCPS).LCL-NCPS is new multi-source signature scheme which has the characteristics of anti-quantum,antipollution and anti-forgery.In LCL-NCPS,each source node user can output a message vector to intermediate node and sink node,and the message vectors from different source nodes will be linearly combined to achieve the aim of improving the network transmission rate and network robustness.In terms of efficiency analysis of space dimension,LCL-NCPS can obtain the lower computation complexity by reducing the dimension of proxy key.In terms of efficiency analysis of time dimension,LCL-NCPS has higher computation efficiency in signature and verification.
