Competitive Advantages:
- Our solution solves the problem of bottleneck by converting it into logarithmic seed storage overhead, which helps in offering the service to different categories of end devices
- In terms of cryptographic audit data and time-combined performance, the suggested OPAS schemes achieve outstanding performance compared to the nearest counterparts
- The suggested EC-based signature schemes offer fast verification time, with small cryptographic storage overhead by introducing a new tree-based data structure to store the one-time ephemeral keys
Summary:
With the advent of more number IoT devices cloud storage is emerging as a service to offload the collected data, as these IoT devices have restricted resources. The data stored on the cloud is mainly medical sensors and cameras, furthermore, this data is stored in different types of clouds according to the accessibility needs and requirements. The data which is not often accessed is called cold data and storing it on regular often accessed servers is expensive. Researchers at the University of South Florida have proposed a new type of cold storage server auditing protocol that could also satisfy the security requirements of the data, and needs of the end-user and is not that expensive. The existing state-of-the-art lacks features that do not make them potential candidates for this type of storage. Our protocol meets the stringent requirements of the end-users with an efficient signing and compact authentication tag for the input data while achieving the standalone performance at the logging server in terms of fast verification and optimal efficiency for the cryptographic audit storage overhead. Our system uses an EC-based optimal-signing signature scheme as a starting point, which helps in addressing the bottleneck of linear storage overhead by introducing a new seed storage management design-based tree-based data structure.
