Communications of usernames and passwords to a plurality of cloud storages via a plurality of communications protocols that change over time

摘要

A computational device has an interface to access a heterogeneous cloud storage comprised of a first cloud storage maintained by a first entity and a second cloud storage maintained by a second entity. The computational device transmits, via a first communications protocol over the interface, a first set of data comprising usernames to a first cloud storage maintained by a first entity. The computational device transmits, via a second communications protocol, a second set of data comprising passwords corresponding to the usernames to a second cloud storage maintained by a second entity. On elapse of a first predetermined amount of time or the first communications protocol being compromised, the first communications protocol is changed to a third communications protocol. On elapse of a second predetermined amount of time or the second communications protocol being compromised, the second communications protocol is changed to a fourth communications protocol.
