Riassunto:

This book describes the implementation of algorithms for providing security and privacy in cloud-based services. The goal is to avoid the various attacks and to identify a better route to transfer the data securely in the cloud environment. The main objective is to design a proactive approach to ensure valid client authentication by the cloud provider. A Two Factor Authentication (TFA) scheme is proposed based on the One Time Password (OTP) which is generated and sent to authorized users through the mail. Accessing the data in cloud environment is done by the client through authentication, authorization, and integrity. HMAC authentication algorithm is proposed for Network as a Service (NaaS) in the cloud environment to design a secured data transmission through Open Shortest Path First (OSPF) routing protocol. To ensure confidentiality in cloud services, a hybrid mechanism is proposed using symmetric and asymmetric cryptography in SaaS and NaaS environments. Authentication and integrity are tested by implementing HMAC with OSPF protocol and various statistical measures like Clock offset, root delay, root dispersion, and peer dispersion of the time is calculated.
