Efficient and secure identity-based multi-signcryption scheme in standard model
Cong Li, De-qin YAN, Hong-liang ZHENG · Journal of Computer Applications · 2013
Faced with the inefficiency problem of current identity-based multi-signcryption schemes,an efficient and secure identity-based multi-signcryption scheme was proposed.The new scheme eliminated the number of multiplicative operations,and increased the procedure of key verification.Furthermore,through security and efficiency analysis in the standard model,the new scheme is proved secure under computational Diffie-Hellman assumption and reduces the calculation work.Compared with the known schemes,the new scheme is more secure and efficient.
