Abstract
A system and a method for accessing data in a secure manner are provided, in which the data comprises a number of data sets and each of the data sets is assigned to a user. The data sets are stored in a database in an encrypted manner, and are decryptable by means of a first decryption key assigned to the particular entity. The first decryption keys are stored in a volatile memory unit, and each of the first decryption keys are encrypted separately using a first and at least a second encryption key assigned to the particular entity, and the encrypted first decryption keys are stored in a permanent memory unit. After the volatile memory unit is erased, the encrypted first decryption keys are copied from the permanent memory unit into the volatile memory unit, and the encrypted first decryption keys are decrypted in the volatile memory unit.
