Abstract:

With the rapid development of cloud computing, models of cloud-based digital signature become practical. More enthusiastic responses from enterprises confirm that cloud computing plays an important role in many fields of IT with its features of reliable, convenient, on-demand network access to security infrastructures that perform cryptographic operations. This paper proposes a scheme of generating digital signature in the cloud. The scheme achieves centralized management of certificates and their private keys, and ensures the security of certificates and their private keys by using the combination of distributed processing with key segmentation. Meanwhile, the scheme presents lower performance requirements of cryptographic operations for cloud signature service platform, which meet the need of simultaneous processing from a large number of users.

Key words: digital signature, cloud computing, certificate, private key
