Abstract
In 2007, Sunder Lal and Tej Singh gave an ID-based multi-proxy multi-signcryption scheme. By analysis, we discover that Sunder Lal and Tej Singh´s scheme wrongly used two types of undefined bilinear pairing calculations, which caused that the calculation of Lal and Tej Singh´s scheme is unfeasible. Against the error, we give an improved scheme. To avoid of using these undefined calculations and make it feasible, the improved scheme takes use of a more Hash function. At last, the security of the improved scheme is analyzed.
