检查网络信息系统中的数据拥有情况，例如与关键基础设施（电力设施、机场、数据库、国防系统等）相关的信息系统，是至关重要的问题。远程数据拥有检查协议允许检查远程服务器可以以这样一种方式访问未损坏的文件，即验证者不需要事先知道正在被验证的整个文件。不幸的是，目前的协议只允许有限数量的连续验证或从计算的角度来看是不切实际的。在本文中，我们提出了一个新的远程数据拥有检查协议，使1）它允许无限数量的文件完整性验证和2）它的最大运行时间可以选择在设置时间和权衡存储在验证器。
Checking data possession in networked information systems such as those related to critical infrastructures (power facilities, airports, data vaults, defense systems, and so forth) is a matter of crucial importance. Remote data possession checking protocols permit checking that a remote server can access an uncorrupted file in such a way that the verifier does not need to know beforehand the entire file that is being verified. Unfortunately, current protocols only allow a limited number of successive verifications or are impractical from the computational point of view. In this paper, we present a new remote data possession checking protocol such that 1) it allows an unlimited number of file integrity verifications and 2) its maximum running time can be chosen at set-up time and traded off against storage at the verifier.
