Recently, cloud has become a new paradigm for delivering computing as a utility. Although the theory behind cloud computing is based on decades of the existing technologies and research, enthusiastic response from developers and widespread acceptance among users confirms that cloud computing is here to stay and likely to play an even more important role as a concept in many fields of information technology, including encryption. Cloud-based digital signature can be seen as a model for reliable, convenient, on-demand network access to security infrastructure that performs cryptographic operations of digital signature. This paper proposes a protocol for data exchange between signer and signing-enabled cloud environment in the cloud-based digital signature model. It also covers performance results and implementation notes of Signer entity.
