摘要： 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., an attestation blockchain).

摘要： The example embodiments are directed to a system and method for secure provisioning of secrets into MPSoC devices using untrusted third-party systems. In one example, the method includes generating a random number sequence from a true random number generator to produce secret information, storing the secret information in an on-chip secure storage, encrypting, in a device and using public key encryption, the secret information to generate an encrypted message, and transmitting the encrypted message to a third-party system.
