The many advantages of cloud computing architecture are increasingly attracting individuals and organizations to outsource their data from local to remote cloud servers. It is a clear trend that cloud data outsourcing is becoming a pervasive service. Along with the widespread enthusiasm on cloud computing, however, concerns on data reliability, security and privacy with cloud data storage are arising. For protecting data privacy, sensitive data has to be encrypted before outsourcing, which obsoletes traditional data utilization based on plaintext keyword search. Thus, enabling an encrypted cloud data search service is of paramount importance.
This talk will first give an overview on data outsourcing in cloud computing, and then discuss challenges and corresponding solutions of reliability, security and privacy which raise as primary obstacles to the adoption of cloud computing. At last, it will present latest research on generic computation outsourcing in cloud computing.
