Abstract
Methods and systems for managing access to data stored in data storage systems are disclosed. An end device and/or user thereof may require access to sensitive data of varying sensitivity levels stored in a data storage system. To prevent malicious parties from gaining access to the sensitive data, an access control system may be implemented. The access control system may include a registration process that registers end device and user combinations and assigns cryptographic key pairs to each registered combination. The key pairs may be generated using information specific to the sensitivity level of the data and managed using a key tree structure. Before sensitive data may be accessed, a requesting device and its associated user may be authenticated using the key pairs generated during registration. The sensitive data may be encrypted using sensitivity level and device-specific encryption.
