(t,n)Threshold Sharing Unsigncryption Scheme Based On the ECC
Xueming Wang · Journal of Guizhou University of Technology · 2007
A(t,n)Threshold sharing unsigncryption scheme with CA based on the ECC is proposed,which combines the advantages of symmetric encryption algorithm,Shamir's threshold and Junn's scheme functions.It not only provides lower computation and communication,but also message confidentiality,authentication,unforgeability,non-repudiation,resisitance of malicious verifiers cheating others and so on,thus it satisfies the request of group communication and has great practical value and application prospect for the restriction of storage and computation developed hardware.In the proposed scheme,the CA can verify sender's signcryption directly without the sender's private key when dispute occurs.Its security is also analyzed.
