  • Patent number: 11095625
    Abstract: Examples disclosed herein relate to data objects associated with private set intersection (PSI). Some examples disclosed herein may enable identifying a set of server elements and a set of data objects. Each data object of the set of data objects may be associated with at least one server element of the set of server elements. Some examples further enable sending the set of server elements and the set of data objects to a client computing device that has a set of client elements. A private set intersection (PSI) between the set of server elements and the set of client elements may be inaccessible by the client computing device, and a subset of the set of data objects that are associated with the PSI may be accessible by the client computing device.

  • Patent number: 11050562
    Abstract: Example implementations relate to attestation. For example, in an implementation, a target device attestation request is transmitted to a target device, where the target device attestation request includes an identity-based encryption (IBE) ciphertext and a retrieval index. The ciphertext is a nonce encrypted using a trusted platform module (TPM) public key together with an IBE public key. The TPM public key is retrieved from a TPM of the target device, and the IBE public key is an expected value presumed to be stored at the TPM.

  • Patent number: 10848305
    Abstract: An example non-transitory computer-readable medium includes instructions that, when executed by a processor, cause the processor to receive a request for data. The instructions also cause the processor to determine a region containing the data based on the metadata. The instructions cause the processor to traverse a tree in the metadata to determine key generation information relating a decryption key for the region to a root key.

  • Patent number: 10686612
    Abstract: Examples set out herein provide a method comprising using first cryptographic key data specific to a computing device to verify a package of machine readable instructions to run on the computing device. The verified package may be executed to generate a random number using a true random number generator of the computing device, and to store the generated random number. Second cryptographic key data may be generated by a pseudorandom number generator of the computing device based on a seed comprising a combination of the random number as a first seed portion and a second seed portion. A portion of the second cryptographic key data may be sent to a certifying authority. The method may further comprising receiving a certification value based on the sent portion of the second cryptographic key data from the certifying authority and storing the certification value.

  • Patent number: 10686589
    Abstract: Example embodiments relate to combining hashes of data blocks. The examples disclosed herein calculate a hash value for each data block in a sequence of data blocks. The hash values are combined into a combined value, where the combined value has the same sequence as the sequence of data blocks. A master hash value is then calculated for the combined value.

  • Patent number: 10389518
    Abstract: A blockchain includes blocks that each store a hash value computed using a hash function from data of the block. Another hash value is computed for each block using a different hash function, and added to the block within the blockchain. New blocks subsequently added to the blockchain have hash values computed using just the different hash function.

  • Patent number: 10374807
    Abstract: Storing and retrieving ciphertext in data storage can include determining a first ciphertext value for a first data chunk to be saved to a client-server data storage system using an encrypted chunk hash value associated with the first data chunk as an initial value, and storing the first data chunk on a server in the client-server data storage system in response to determining that the first ciphertext value is a unique ciphertext value. Also, storing and retrieving ciphertext in data storage can include decrypting a ciphertext value for a second data chunk received from a client in the client-server data storage system and based on an encrypted chunk hash value associated with the second data chunk, and sending the second data chunk to the client in response to determining that the decrypted ciphertext value corresponds to an original data chunk saved to the server by the client.
