In a distributed system, a computer system responsible, at least in part, for complying with a cryptographic key usage limit for a cryptographic key, obtains results of cryptographic operations generated based at least in part on the cryptographic key and transmits the obtained results over a network. The computer system digitally signs the results and provides the results with digital signatures of the results. Another device intercepts the results and allows the results to proceed to their destination contingent on successful validation of the digital signature.

Data loss prevention with key usage limit enforcement

Nodes in a distributed system utilize the same cryptographic key, where the cryptographic key is subject to a usage limit. The usage limit is allowed to be temporarily exceeded. When the usage limit is exceeded, results of exceeding the usage limit are corrected to mitigate the effects of exceeding the usage limit.

Optimistic key usage with correction

Techniques for providing access to data are disclosed. In an embodiment, a method for providing access to data involves storing data among a plurality of data stores where at least two of the data stores differ in at least one ability to perform a data operation. A mapping associates data containers with locations of corresponding data among the data stores. At least a portion of the data is redistributed among the data stores according to at least one policy that defines where among the data stores said at least a portion of the data should be stored. A request from a requestor to access particular data corresponding a data container is received and the particular data is located using the mapping. The particular data is provided to the requestor.
