摘要： A module such as an M2M device or a mobile phone can include a removable data storage unit. The removable data storage unit can include a nonvolatile memory, a noise amplifying memory, and a cryptographic unit. The nonvolatile memory can include (i) shared memory for access by both the module and the cryptographic unit, and (ii) protected memory accessible only by the cryptographic unit. The cryptographic unit can use a noise memory interface and noise amplifying operations in order to increase and distribute bit errors recorded in the noise amplifying memory. The cryptographic unit can (i) generate a random number using the noise amplifying memory and (ii) input the random number into a set of cryptographic algorithms in order to internally derive a PKI key pair. The private key can be recorded in protected memory and the public key signed by a certificate authority.

摘要： A system for secure data transfer using air gapping. A first module includes: a first module communication interface configured to communicate with a public network. A second module includes: a first read-only memory storing an operating system; a second read-only memory storing sets of private keys of the second module and at least one public key of another remote entity; a cryptographic unit configured to encrypt and/or decrypt data using the keys stored in the second read-only memory. A bridge module includes: a bridge module controller; memory for storing data; a switch configured to selectively connect the bridge module data interface to either the first module data interface or to the second module data interface such that the first module data interface is never connected with the second module data interface.

摘要： A server can receive a device public key and forward the device public key to a key server. The key server can perform a first elliptic curve Diffie-Hellman (ECDH) key exchange using the device public key and a network private key to derive a secret X1. The key server can send the secret X1 to the server. The server can derive an ECC PKI key pair and send to the device the server public key. The server can conduct a second ECDH key exchange using the derived server secret key and the device public key to derive a secret X2. The server can perform an ECC point addition using the secret X1 and secret X2 to derive a secret X3. The device can derive the secret X3 using (i) the server public key, a network public key, and the device private key and (ii) a third ECDH key exchange.

摘要： A secure update is provided from a server to an end-point device. The server registers digital information, such as a name or a software package, and a verifiable key, such as a cryptographic hash, derived from the digital information. A publicly accessible transaction log stores the verifiable key in a block and provides an identifier of the block to the server. An end-point device receives the digital information and the identifier, and computes a separate verifiable key. The end-point device retrieves the verifiable key from the block of the publicly accessible transaction log, and compares the retrieved verifiable key to the separate verifiable key to determine whether the digital information has been compromised.

摘要： An architecture and methods for self-sovereign digital identity is described. The method mimics the handling of identities in the physical world, by provisioning unique digital identities to people. Digital identities and consent tokens are said to be self-sovereign because they are tightly controlled by their owners using identity engines installed on personal devices. Identity engines are interoperable, establishing a web identity layer. Self-sovereign digital identities are used to identify their holders, sign and encrypt transactions, and create digital seals that cannot be repudiated. Digital seals affix the identities and attestations of collaborating parties to digital identities, consent tokens, transactions, documents, and other artifacts. Self-sovereign digital identities can be exchanged securely, verified using proof-of-possession and proof-of-custody tests when collaborating synchronously, and verified using a proof-of-existence identity registry when collaborating asynchronously.

摘要： The disclosure provides systems and methods for maintaining integrity of documents and activities associated with examinations. The systems and methods store such activities and documents in a distributed blockchain such that integrity is maintained through transparency and redundancy of the records and activities. The systems monitor for any anomalies and notify appropriate individuals when an anomaly is detected, as well as maintaining a log of such anomalies.

摘要： Techniques for securely provisioning a set of enclaves are described. A contract owner may register with a shared registry. A subset of enclaves may be selected to be provisioned from among a plurality of enclaves. A keyshare may be requested from one or more provisioning services for each of the subset of enclaves to be provisioned. The requested keyshares may be received from each provisioning service for each of the subset of enclaves to be provisioned. For each of the selected enclaves, the received keyshares may be sent for verification by the enclave. Each of the selected enclaves may send an authenticated and encrypted key derived from the received keyshares.
