This paper proposed the hierarchical identity-based cryptosystem in order to improve the efficiency of the identity-based cryptosystem.Additionally,the hierarchical identity-based signature is an important part of the hierarchical identity-based cryptosystem.At first,described the definition and the security model of a hierarchical identity-based signature scheme.Secondly,introduced several hierarchical identity-based signature schemes.And analyzed the construction,security and efficiency of the schemes.Finally,pointed out the development trend and study direction of hierarchical identity-based signature schemes.
