Abstract: Systems and methods for cleaning and/or removal of ocean garbage are provided. The system includes a cleanup autonomous vessel (CAV) for collecting garbage, an autonomous tugboat (AT) for moving a large ocean container (LC), and a sorting machine (SM) and for sorting garbage. The system may also include an autonomous boat (AB) for transferring garbage from the CAV to the SM and for supplying fuel from the AT to the CAV. The system further includes regular ocean vessels (ROV) for moving the LC to different location. The CAV, AT, AB, LC, and ROV may operate in conjunction with a bidding process.

Abstract: In an embodiment, an electronic data security system improves the security and usability of encrypted electronic data using a symmetric key approach implemented by security engines embedded on operably coupled integrated circuits. Engines paired to integrated circuits in combinations of hardware and software engines implementing security tasks can also be utilized. A first security engine is configured to interface to a second security engine and, using the components of the respective security engines, securely exchange electronic data using symmetric key encryption. The key change instruction configures the second security engine private key for a subsequent transmission.
