Abstract

A method and system is disclosed for securing a Distributed Storage Network (DSN) memory from unauthorized access from users. The method and system secures the DSN memory by providing access to at least a sufficient number of distributed storage units placed in a Write Only (WO) mode.

Method and System for Securing a Distributed Storage Network Memory from Unauthorized Access from Users

Disclosed is a method and system for securing a Distributed Storage Network (DSN) memory from unauthorized access of users. The method and system secures the DSN memory by providing access to at least a sufficient number of distributed storage units placed in a Write Only (WO) mode.

The method and system analyzes whether at least a sufficient number of the distributed storage units operating within the DSN memory are able to preclude an Information Dispersal Algorithm (IDA) threshold number of data slices and placing the respective distributed storage units in the WO mode. Here, in the WO mode, the distributed storage units normally respond to write requests and also respond to data check and lists requests normally. However, the distributed storage units do not respond to any remotely received read requests. Further, the method and system maintains data reliability by operating rebuilding function only in Zero Information Gain Rebuilding (ZIG) mode and by returning encrypted partially rebuilt data slices rather than building raw slice data. Later, the data stored in the DSN memory operating in the WO mode is recovered by directly collecting slices from each distributed storage unit, by extracting data from memory devices or other direct physical interfaces of the distributed storage units.

Thus, the method and system disclosed herein provides an effective tec...
