Abstract: Some embodiments provide a system to protect an electric vehicle charging infrastructure. An electric vehicle charging site may receive AC power from a power grid and provide DC power to electric vehicles. The charging site may include a plurality of monitoring nodes each generating a series of current monitoring node values over time that represent a current operation of the electric vehicle charging infrastructure. A supply equipment communication controller may receive an access request from an access requestor associated with an electric vehicle, the access request being associated with a platform certificate. A secondary actor policy decision point at the charging site may evaluate the access requestor's identity and respond with an action message allowing high-level communication with the access requestor to proceed. Note that information associated with the current monitoring node values and/or the access request may be stored in a secure, distributed transaction ledger (e.g.

Abstract: The invention relates to distributed ledger technologies such as consensus-based blockchains. Computer-implemented methods for a trustless, deterministic state machine are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network. The first transaction includes a first script that, as a result of being executed, causes the node to at least obtain a first set of field values of the first transaction, a second set of field values of a second transaction, and an input. The second transaction is obtained.

Abstract: One variation of a method for secure and distributed timekeeping includes: at a node in a set of nodes in a network, at a first time, sampling two time sources and calculating a minor consensus time between the two time sources; in response to designation of the node as a leader node, accessing a second minor consensus time generated by a second node, accessing a third minor consensus time generated by a third node, calculating a first major consensus time between the first, second, and third minor consensus times, and distributing a request to validate the first major consensus time; and, based on validation of the request from a threshold quantity of nodes, cryptographically hashing a hash of a previous block and the major consensus time to generate a first block and distributing the first block to each node in the set of nodes.

Abstract: Detecting and preventing selected events within a computing environment. A determination is made as to whether a selected event of the computing environment is consistent with a historical pattern of selected events of the computing environment. Based on determining the selected event is inconsistent with the historical pattern of selected events, processing associated with the selected event is delayed. Based on delaying processing associated with the selected event, a determination is made as to whether the selected event is valid. Based on determining that the selected event is valid, processing associated with the selected event is resumed.

Abstract: A boot image is modified to require authentication based on stable system values that are uniquely associated with a storage array. The stable system values may be used as a key to decrypt a password. The modified boot image will not allow booting to proceed without the decrypted password. The password cannot be decrypted based on different stable system values such as the stable system values of other storage arrays.

A method includes receiving, from a user device (104a, 104b), a request for a security rating of a smart space (102), calculating the security rating of the smart space (102) based at least in part on security information regarding the smart space (102), the security information received from a plurality of user devices (104a, 104b), and transmitting the security rating of the smart space (102) to the user device (104a, 104b).

Abstract: Techniques and systems described below relate to systems and methods to migrate a blockchain account. A blockchain migrate transaction can migrate an existing account from an old address to a new address. A blockchain account migration can be performed in response to a determination that a secret key associated with an address has or has potentially been exposed. Existing digital assets associated with a potentially compromised account may be carried over to a new account as part of a blockchain account migrate transaction.

Abstract: A method applied to a mining machine for limiting computing power includes utilizing a dictionary library and a timestamp to control Nonce combination that can be tried per unit time. If all strings in the dictionary library have been tried, as long as a time difference between time of generating most recent timestamp and the current time is less than a preset threshold, the mining machine must wait in sleep state and cannot resume mining until the time difference exceeds the preset threshold. The present disclosure can avoid a situation that the calculation power of the mining machine is too strong and causes a monopoly of the calculation power.
