Abstract

Software as a Service (SaaS) is a kind of *aaS distribution and deployment model in which applications are provided to customers as a service. The applications can run on the user’s computing systems or the CSP’s Web servers. The solution may belong to a software company, which host it among a CSP and offer it as instances to customers. As mentioned [1] software piracy is the major concern of software’s publisher; lot of solution has been set up, but editors still suffer and lot of copies was made or the solution was cracked. Our proposed design demonstrate how software protection can be protected from redistribution and tampering. The aim is to secure instance access through the new specification of TPM 1.2[13] that is time stamping to have the exclusive access to an instance or result of software computation, so only one person can have the access. Besides the new design, combined to the TCCP design [12] protects side channel attacks and/or attacks from the sysadmin.
