Signature,widely used in cloud environment,describes the work as readily identifying its *** existing signature schemes in the literature mostly rely on the Hardness assumption which can be easily solved by quantum *** this paper,we proposed an advanced quantum-resistant signature scheme for Cloud based on eisenstein ring(ETRUS)which ensures our signature scheme proceed in a lattice with higher *** proved that ETRUS highly improve the performance of traditional lattice signature ***,the Norm of polynomials decreases significantly in ETRUS which can effectively reduce the amount of polynomials convolution ***,storage complexity of ETRUS is smaller than classical ***,according to all convolution of ETRUS enjoy lower degree polynomials,our scheme appropriately accelerate 56.37%speed without reducing its security level.

We propose a novel method to compute a cubic root of a cubic residue in eisenstein *** applying our method,a new identity based signature scheme is proposed based on cubic *** formally prove that our scheme is secure against existential forgery on the adaptive chosen message and identity attacks assuming the hardness of *** scheme is the first identity based signature scheme based on cubic residues.
