According to the deficiencies of the authentication schemes in current cloud services, this paper proposes a more Efficient ID-Based Signature scheme (E-IBS), which is based on the elliptic curve discrete log problem. By replacing the paring computation with scalar multiplication, the computation costs are reduced dramatically, which makes a great contribution on improving the authentication efficiency. In addition, an authentication protocol between users and cloud servers is designed based on the E-IBS scheme which can achieve users' rapid and efficient access.
