Rainbow is an effective multivariate digital signature scheme proposed by Ding and Schmidt. However, a lot of attacks against it have been proposed. To resist all these attacks, designer should be very careful with its choice of parameters. In this study, the authors will propose a new approach to build a secure variant of Rainbow. According to our security analysis, it could resist all the existing attacks against Rainbow and save some memory in the meantime.
