Embodiment Construction
[0056] In the following, the present invention will be described with reference to the accompanying drawings. In the following description, some specific embodiments are only for the purpose of description, and should not be construed as limiting the present invention in any way, but are only examples of the present invention. Conventional structures or constructions are omitted so as not to obscure the understanding of the present invention.
[0057] Principle Description
[0058] The Incremental Provable Data Integrity (IPDI) scheme proposed here not only overcomes all the problems encountered in the prior art, but also outperforms various existing technologies in performance.
[0059] The IPDI scheme basically has the following three steps, which is the same as figure 1 The working model shown matches.
[0060] Step 0':
[0061] The IPDI scheme requires a finite cyclic group . Preferably, is a finite cyclic group on elliptic curves. In the present disclosure, th...
