Abstract: Example methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement contextual key management for data encryption are disclosed. Example apparatus disclosed are to determine whether a key mapping is associated with a combination of two or more context rules defined for a set of context values associated with input data to be encrypted. Disclosed example apparatus are also to, in response to a determination that no key mapping is associated with the combination of two or more context rules, map a key identifier to the combination of two or more context rules and generate a key corresponding to the key identifier. Disclosed example apparatus are further to encrypt the input data based on the key to obtain encrypted data.

Abstract: One or more identifiers respectively corresponding to a one or more logical blocks in an electronic file system volume is selected. One or more logical blocks respectively corresponding to the selected one or more identifiers is analyzed according to one or more criteria. A value is assigned to one or more indicators associated with each of the one or more logical blocks and corresponding to the one or more criteria, in response to the analyses of the corresponding one or more logical blocks. A representation of the one or more indicators, and their respective assigned values, associated with each of the one or more logical blocks that was analyzed according to the one or more criteria, is generated. In some embodiments, an action to be performed on or with an electronic file mapped to the logical blocks is controlled based on one or more of the values assigned to the one or more indicators associated with the one or more logical blocks.

Abstract: Example methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement contextual key management for data encryption are disclosed. Example apparatus disclosed herein to perform contextual encryption key management, which are also referred to herein as contextual key managers, include an example context discoverer to discover context information associated with a request to access first encrypted data. Such disclosed example apparatus also include an example contextual key mapper to identify a combination of context rules associated with a key that is to provide access to the first encrypted data, validate the context information associated with the request based on the combination of context rules associated with the key to determine whether the request to access the first encrypted data is valid, and obtain the key from a key management service when the request to access the first encrypted data is valid.
