description Systems and methods are described for providing storage of encrypted data sets, deduplication of such data sets, and control of the redundancy of those data sets. A form of modified convergent encryption can be employed, whereby an encryption key for a data set is selected based on a combination of the plaintext of the data set and a salt value, with the salt value being selected from a number of permutations corresponding to a desired redundancy of the data set in a storage system. Accordingly, a given data set can result in a number of ciphertexts equal to the desired redundancy, and deduplication can occur by removing duplicative instances of individual ciphertexts. Salt values can be selected according to a variety of criteria, including user-based, time-based, and location-based criteria.
