Latest Patents

One of his latest patents is titled "Efficient deduplication using block-based convergent encryption." This invention describes systems and methods for providing secure storage of data sets while enabling efficient deduplication of data. Each data set can be divided into fixed-length blocks, and the plaintext of each block can be convergently encrypted. By using a hash of the plaintext as an encryption key, block-level ciphertext can be generated and stored. If two data sets share blocks, the resulting block-level ciphertext can overlap, allowing for the elimination of duplicative ciphertexts. A manifest is created to facilitate the re-creation of the data set, identifying the block-level ciphertexts and the keys used for encryption. This method allows for significant deduplication of nearly identical data sets, even if they are not perfectly identical.

Another notable patent is "Redundancy controls in convergent encryption using dynamic salt values." This invention provides systems and methods for storing encrypted data sets, deduplicating them, and controlling redundancy. A modified form of convergent encryption is employed, where an encryption key is selected based on a combination of the plaintext and a salt value. The salt value is chosen from various permutations that correspond to the desired redundancy in a storage system. This approach allows for multiple ciphertexts to be generated from a single data set, facilitating deduplication by removing duplicative instances of individual ciphertexts. Salt values can be selected based on user, time, and location criteria.
