Original Abstract Submitted
Methods and systems for data security are provided. The method includes generating respective tags for data segments in a dataset, deriving respective temporal keys associated with the respective tags for the plurality of data segments from a master key, and transforming the plurality of data segments from a plaintext to a ciphertext using the respective temporal keys as a first input and the respective tags as a second input, while format-preserving the data segments. The master key can be updated to prevent from reverse-transforming a selected data segment in the dataset from the ciphertext to the plaintext.
