Technologies for providing attestation for function as a service flavors include a compute device including circuitry configured to obtain function definition data indicative of a set of operations to be performed in a function and a set of hardware resources to be utilized by the function, execute a benchmark operation to produce benchmark data indicative of a measured performance of the function, and sign the function definition data and the benchmark data to produce function flavor data. The circuitry is also configured to provide the function flavor data to one or more other compute devices for validation that the function, when executed on the hardware resources, provides the measured performance and write, to a distributed ledger, the function flavor data.

Apparatus and associated methods relate to securely transmitting, directly between two mobile devices, AES-256 encrypted file attachments which are decrypted within an application program (APP) using a decryption key that is available only to the APP. In an illustrative embodiment, the encrypted file may be attached to an e-mail. The e-mail may be transmitted directly to another mobile device via direct Wi-Fi, for example. The e-mail may be transmitted directly to another mobile device using Bluetooth, for example. In encrypted attachment may be deciphered only within the APP running on the receiving mobile device using a private key accessible to only the APP.

A data transfer process can include multiple verification features usable by a “source” device to ensure that a “destination” device is authorized to receive a requested data object. The source device and destination device can communicate via a first communication channel (which can be on a wide-area network) to exchange public keys, then use the public keys to verify their identities and establish a secure session on a second communication channel (which can be a local channel). The data object can be transferred via the secure session. Prior to sending the data object, the source device can perform secondary verification operations (in addition to the key exchange) to confirm the identity of the second device and/or the locality of the connection on the second communication channel.

A computer-implemented method according to one embodiment includes receiving at an encryption daemon a key request from a storage device; implementing, by the encryption daemon, a secure communications channel between the encryption daemon and an encryption key server; sending the key request from the encryption daemon to the encryption key server, utilizing the secure communications channel; receiving, from the encryption key server at the encryption daemon, an encrypted response, utilizing the secure communications channel; decrypting, by the encryption daemon, the encrypted response to obtain the requested key, and sending the requested key from the encryption daemon to the storage device.

The concepts and technologies disclosed herein are directed to quantum key distribution (“QKD”) networking as a service. According to one aspect disclosed herein, a microservices controller can establish a plurality of quantum connections with a plurality of virtual quantum connection managers (“vQCMs”) deployed in association with a set of quantum user nodes (“QUNs”) in a QKD network. The microservices controller can receive a request to initialize the QKD network. The microservices controller can coordinate with the plurality of vQCMs to handle initialization of the QKD network. The microservices controller can receive a QKD service request from a QKD network operator. The microservices controller can invoke a plurality of microservices to handle the QKD service request.

A method of pairing a user device with a remote system. The user device communicates with an intermediary device via a secure communication channel to cause a secret key generated by the remote system to be received by the user device, from the intermediary device. The secret key is thereby assigned to the user device. The user device establishes communication with the remote system to pair the user device with the remote system using the secret key, such that data sent from the user device to the remote system is encrypted using the secret key and data received by the user device from the remote system is decrypted using the secret key.

One embodiment provides a device that includes one or more line of sight transmitters configured to transmit signals over a line of sight communications medium, one or more transmitters configured to transmit signals over another communications medium and a controller. The controller is configured to perform an operation that includes retrieving a key adapted for use in decrypting encrypted content. The operation further includes transmitting the key to a second device over the line of sight communications medium using the one or more line of sight transmitters. Additionally, the operation includes encrypting data such that the data can be decrypted using the retrieved key. The operation also includes transmitting the encrypted data to the second device over the other communications medium using the one or more transmitters, where the second device is configured to decrypt the encrypted data using the key received over the line of sight communications medium.

An electronic key fob device, in one embodiment, includes a transmitter, a counter configured to provide a current counter value indicated by a plurality of bits, a memory configured to store an operation key, and a processor coupled to the transmitter and memory. The processor is configured to encrypt the current counter value using the operation key to produce an encrypted counter value, select a subset of the plurality of bits of the current counter value, transmit a message the includes the encrypted counter value and the subset of plurality of bits of the current counter value.

One-time-pad (OTP) encryption systems and methodologies are resistant to cracking, even by advanced quantum computers. In contrast to some purported solutions, the required elements of an unbreakable OTP system are preserved under Claude Shannon's mathematical proof. In alternative embodiments, the invention uses a secure network to reconstitute blockchain systems without the use of asymmetric encryption. Described extensions of these block chain systems are described which enable an entirely new set of applications for protecting privacy, sharing information, performing validations and analysis of data, and creating system actions that are constrained by complex data algorithms.

A method for end-to-end transmission of a piece of encrypted digital information includes the following steps: selection, on the computer equipment of the transmitter, of a piece of digital information and a digital identifier of the recipient; temporary encryption of the piece of digital information by execution of a local encryption application on the computer equipment with the private key of the sender; decryption of the piece of information on the equipment of the sender and encryption of the piece of information with the public key of the recipient; transmission to the recipient, by the computer equipment, from the sender, of the piece of digital information encrypted with the public key of the sender, optionally by the intermediary of the transactional platform; and decryption by the computer equipment of the recipient of the piece of information with the public key of the sender.
