The disclosure relates to systems, methods and computer readable for generating double encryption of data through discrete modules that are air gapped at every stage. Furthermore, the transceivers disclosed can operate in “off-line” mode which can be adapted to communicate with any network access terminal regardless of the intermediate connecting network.

Disclosed are systems, methods, devices, and computer-readable media for offloading lattice-based cryptographic operations to hybrid cloud computing system. In one embodiment, a method is disclosed comprising receiving a first network request from a client device via a secure application programming interface (API), the request including unencrypted data; encrypting the unencrypted data using an algorithm that generates homomorphically encrypted data; issuing a second network request to a second API of a cloud platform, the second network request including the encrypted data; receiving a response from the cloud platform in response to the second network request; and transmitting, in response to the first network request, a result to the client device based on the response, the result obtained by decrypting an encrypted output returned by the cloud platform.

A method implemented in a computing system hosting a three-dimensional virtual reality world. The computer system stores a set of searchable records, each having: a searchable hash of at least a portion of personally identifiable information; and an encrypted identity, decryptable using an encryption key generated based at least in part on the searchable hash and a global key. In response to a search request identifying at least a portion of personally identifiable information as a search criterion, the computer system generates a hash of the search criterion, and finds a matching searchable record that has a searchable hash equal to the hash computed from the search criterion. An encryption key is computed based on the global key and the matched searchable record to decrypt an encrypted identity of a user having at least the portion of personally identifiable information that is the search criterion in the search request.

A server determines an array [[addr]] indicating a storage destination of each piece of data, generates an array of concealed values, and connects the generated array to the array [[addr]] to determine an array [[addr′]]. The server generates a sort permutation [[σ.sub.1]] for the array, applies the sort permutation [[σ.sub.1]] to the array [[addr′]], and converts the array [[addr′]] into an array with a sequence composed of first Z elements set to [[i]] followed by α.sub.i elements set to [[B]]. The server generates a sort permutation [[σ.sub.2]] for the converted array [[addr′]], generates dummy data, imparts the generated dummy data to the concealed data sequence, applies the sort permutations [[σ.sub.1]] and [[σ.sub.2]] to the data array imparted with the dummy data, and generates, as a secret hash table, a data sequence obtained by deleting the last N pieces of data from the sorted data array.

Data privacy is a major concern when accessing and processing sensitive medical data. Homomorphic Encryption (HE) is one technique that preserves privacy while allowing computations to be performed on encrypted data. An encoding method enables typical HE schemes to operate on real-valued numbers of arbitrary precision and size by representing the numbers as a series of polynomial terms.

A method of securely dispersing private user data may include operating a software application configured to utilize user data, receiving the user data, generating a sequence of random bits, and generating a plurality of secret shares from the user data. Generating the plurality of secret shares may include selecting a subset of the user data for each secret share and combining the subset of the user data with the sequence of random bits. The subset of the user data may be a first half of the user data for a first secret share, a second half of the user data for a second secret share, and the whole user data for a third secret share. The method may also include dispersing each of the secret shares.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing sensor communications in a monitored environment. One of the methods includes receiving, by a server and from a device that is accepted to connect with a first network using acceptance data that includes a first key indicating the device is associated with the first network, a request a) to join a second network different from the first network b) that identifies the first key; determining, by the server and using the identification of the first key in the request, that the device that transmitted the request is associated with the first network; and providing, by the server, an notification i) to a user associated with the first network ii) indicating that the device has moved outside the first network.

A mesh network system suitable for connection to a cloud server is provided. The system includes: a first node device, configured to store a first private key and encrypt to-be-verified data according to the first private key to generate first encrypted data; and a second node device, configured to receive the first encrypted data and send the first encrypted data to the cloud server. After sending the first encrypted data, the second node device obtains, from the cloud server, second encrypted data generated by encrypting a first key according to the first public key. The second node device sends the second encrypted data to the first node device. The first node device decrypts the second encrypted data according to the first private key to obtain the first key from the second encrypted data, and performs encrypted communication with the cloud server according to the first key.

Methods, systems, and devices for enabling public key infrastructure (PKI) in the generic could environment and the network function virtualization (NFV) environment. A host device may receive, from an orchestrator of a computer network environment, an indication of a workload to be executed by a virtual machine (VM) hosted on the host device, where the indication includes an identifier of the workload. The VM may transmit a request for a certificate to a hardware security module associated with the host device including the identifier of the workload. After transmitting the request for the certificate, the VM may receive the requested certificate from the HSM. In some cases, the VM may determine a private key associated with the workload and include the private key within the request for the certificate. Additionally or alternatively, the HSM may determine the private key. Here, the HSM may include the private key within the certificate.

A method for maintaining state and event information for all of a user's devices associated in a common location using a blockchain where each block includes an event block and a device block within it, where each event and device block refers to an earlier block of the respective type, resulting in a blockchain-in-a-blockchain architecture. The device and event blocks store data regarding each device associated with a user and events related to the devices/user, respectively. Any time a new event occurs, or a device is registered or removed, a new set of blocks is created, where submissions regarding device changes or events can be made by any participant due to the decentralized and public nature of a blockchain. The result is a system where all data regarding a user's registered devices and events is kept in a common location in a manner that is auditable and verifiable.
