A system described herein provides for the secure maintaining and providing of information, such as public keys used in Public Key Infrastructure (“PKI”) techniques or other techniques, using a distributed ledger (e.g., “blockchain”) system with a fallback to a key escrow system. A first device may encrypt a communication using a first key, and output the encrypted communication to a second device. The first device may attempt to record a second key, that is associated with the first key, to the blockchain system, and may determine that the second key was not recorded to the blockchain system based on the attempt. The first device may output the second key to a third device based on determining that the second key was not recorded to the blockchain system. The second device may obtain the second key from the third device, and use the second key to decrypt the encrypted communication.

A system described herein provides for the secure maintaining and providing of information, such as public keys used in Public Key Infrastructure (“PKI”) techniques or other techniques, using a distributed ledger (e.g., “blockchain”) system. A first device may output a first request to a second device to establish a communication session between the first device and the second device, where the request includes a first value. The first device may receive a second request from the second device, including a second value, to establish the communication session between the first device and the second device. The first device may determine, based on a comparison of the first and second values, that the first device should initiate an establishment procedure of a blockchain associated with the communication session between the first device and the second device, and may accordingly output a blockchain establishment message to a set of devices.

Disclosed herein is a storage platform for managing privacy compliance in an organization. The storage platform comprises a plurality of storage servers and at least one storage controller. The at least one storage controller receives user data from a user associated with the organization and splits the user data into a plurality of data chunks. Further, each data chunk of the plurality of data chunks are stored on a separate storage server selected from the plurality of storage servers. Also, each of the plurality of data chunks are encrypted using encryption keys stored on a distributed ledger. Thereafter, an authentication token corresponding to the stored user data is generated and provided to the user to enable the user to securely share the stored user data with the organization.

The present disclosure relates to a method and device for performing an elliptic curve cryptography computation comprising: twisting, by a first device based on a first index of quadratic or higher order twist (d), a first point (P′KB) on a first elliptic curve over a further elliptic curve twisted with respect to the first elliptic curve to generate a twisted key (PKB); transmitting the twisted key (PKB) to a further device; receiving, from the further device, a return value (ShS) generated based on the twisted key (PKB); and twisting, by the first device based on the first index of quadratic or higher order twist (d), the return value (ShS) over the first elliptic curve to generate a result (ShS′) of the ECC computation.

A method for conveying auditable information regarding provenance of a product that is cryptographically accurate while retaining complete anonymity of product and participant on a blockchain includes: receiving a product identifier; generating a digital token by applying a hashing algorithm to the product identifier; generating an entry value by applying the hashing algorithm to a combination of an event identifier and the digital token; generating a digital signature by digitally signing a data package using a private key of a cryptographic key pair, where the data package includes at least a blockchain address, the event identifier, and the digital token; and transmitting the blockchain address, the digital signature, and the entry value to a node in a blockchain network.

The present application describes a method, system, and non-transitory computer-readable medium for generating new keys during a secure communication session. A key derivation function is operatively connected to both a counter and a memory. The key derivation function generates new key material from a first input and a second input in response to a signal provided by the counter. The key derivation function generates the new key material and outputs it to the memory.

A security device is provided. The security device includes: a communication antenna for receiving a communication signal; and a random number generator for newly generating a random number based on the communication signal received in the communication antenna.

The present disclosure relates to systems and methods for communicating over a network, including encrypting and decrypting communications of data over the network for providing enhanced security utilizing a blockchain-encryption process and a global device ledger. The following also discloses systems for device and session initialization, automation, data capture, security, providing alerts, personalization of settings, and other objectives described in the disclosure. Methods of establishing and monitoring network communications are also disclosed.

Apparatuses, systems, and techniques to generate a trusted execution environment including multiple accelerators. In at least one embodiment, a parallel processing unit (PPU), such as a graphics processing unit (GPU), operates in a secure execution mode including a protect memory region. Furthermore, in an embodiment, a cryptographic key is utilized to protect data during transmission between the accelerators.

Methods and systems for consensus-based online authentication are provided. An encryption device may be authenticated based on an authentication cryptogram generated by the encryption device. The encryption device may transmit a request for security assessment to one or more support devices. The support devices may individually assess the encryption device, other security devices, and contextual information. The support devices may choose to participate in a multi-party computation with the encryption device based on the security assessments. Support devices that choose to participate may transmit one or more secret shares or partial computations to the encryption device. The encryption device may use the secret shares or partial computations to generate an authentication cryptogram. The authentication cryptogram may be transmitted to a decryption device, which may decrypt the authentication cryptogram, evaluate its contents, and authenticate the encryption device based on its contents.
