Abstract: Various examples are directed to system and methods for authenticating a first computing system and a second computing system. The first computing system may receive second system sending data from the second computing system. The first computing system may generate first composite data based at least in part on the second system sending data and first system receiving data. The first computing system may determine that the first composite data is consistent with first composite reference data. The first computing system may generate first tag data based at least in part on the first composite data and send a request message comprising the first tag data to the second computing system. The first computing system may also receive a reply message comprising second tag data from the second computing system and determine that the second tag data is consistent with reference tag data.

Abstract: Various examples are directed to systems and methods for providing access to computing resources. A resource system may receive an access request from a first user. The access request may comprise resource data describing a computing resource and function data describing a requested function to be performed on the computing resource. The resource system may determine that credential data provided by the first user is valid. The resource system may identify secondary data for the access request and generate an access object based at least in part on access object fragment data and the secondary data. The resource system may execute the access object to enable performance of the requested function on the computing resource.

Abstract: Various examples are directed to machines and methods for disassembling and reassembling data structures. An ordered set of functions may be applied to a data array comprising a plurality of data units, each associated with a unique coordinate set. Data units returned by the ordered set of functions may be written in order to one or more disassembled data containers.
