Replay protection for memory based on key refresh
The present disclosure is directed to systems and methods for providing protection against replay attacks on memory, by refreshing or updating encryption keys. The disclosed replay protected computing system may employ encryption refresh of memory so that unauthorized copies of data are usable for a limited amount of time (e.g., 500 milliseconds or less). The replay protected computing system initially encrypts protected data prior to storage in memory. After a predetermined time or after a number of memory accesses have occurred, the replay protected computing system decrypts the data with the existing key and re-encrypts data with a new key. Unauthorized copies of data (such as those made by an adversary system/program) are not refreshed with subsequent new keys. When an adversary program attempts to use the unauthorized copies of data, the unauthorized copies of data are decrypted with the incorrect keys, which renders the decrypted data unintelligible. |

Methods to strengthen cyber-security and privacy in a deterministic internet of things
Methods to strengthen the cyber-security and privacy in a proposed deterministic Internet of Things (IoT) network are described. The proposed deterministic IoT consists of a network of simple deterministic packet switches under the control of a low-complexity ‘Software Defined Networking’ (SDN) control-plane. The network can transport ‘Deterministic Traffic Flows’ (DTFs), where each DTF has a source node, a destination node, a fixed path through the network, and a deterministic or guaranteed rate of transmission. The SDN control-plane can configure millions of distinct interference-free ‘Deterministic Virtual Networks’ (DVNs) into the IoT, where each DVN is a collection of interference-free DTFs. The SDN control-plane can configure each deterministic packet switch to store several deterministic periodic schedules, defined for a scheduling-frame which comprises F time-slots. The schedules of a network determine which DTFs are authorized to transmit data over each fiber-optic link of the network. These schedules also ensure that each DTF will receive a deterministic rate of transmission through every switch it traverses, with full immunity to congestion, interference and Denial-of-Service (DoS) attacks. Any unauthorized transmissions by a cyber-attacker can also be detected quickly, since the schedules also identify unauthorized transmissions. Each source node and destination node of a DTF, and optionally each switch in the network, can have a low-complexity private-key encryption/decryption unit. The SDN control-plane can configure the source and destination nodes of a DTF, and optionally the switches in the network, to encrypt and decrypt the packets of a DTF using these low-complexity encryption/decryption units. To strengthen security and privacy and to lower the energy use, the private keys can be very large, for example several thousands of bits. The SDN control-plane can configure each DTF to achieve a desired level of security well beyond what is possible with existing schemes such as AES, by using very long keys. The encryption/decryption units also use a new serial permutation unit the very low hardware cost, which allows for exceptional security and very-high throughputs in FPGA hardware. |

Discovery routing systems and engines
The inventive subject matter provides apparatus, systems, and methods that improve on the pace of discovering new practical information based on large amounts of datasets collected. In most cases, anomalies from the datasets are automatically identified, flagged, and validated by a cross-validation engine. Only validated anomalies are then associated with a subject matter expert who is qualified to take action on the anomaly. In other words, the inventive subject matter bridges the gap between the overwhelming amount of scientific data which can now be harvested and the comparatively limited amount analytical resources available to extract practical information from the data. Practical information can be in the form of trends, patterns, maps, hypotheses, or predictions, for example, and such practical information has implications in medicine, in environmental sciences, entertainment, travel, shopping, social interactions, or other areas. |

Programming process combining adaptive verify with normal and slow programming speeds in a memory device
Techniques are provided to adaptively determine when to begin verify tests for memory cells during a program operation. The memory cells are programmed using a normal programming speed until their threshold voltage exceeds an initial verify voltage. The memory cells are then programmed further using a reduced programming speed until their threshold voltage exceeds a final verify voltage. In one aspect, a count of memory cells which exceeds the initial verify voltage is used to determine when to begin verify tests for a higher data state. In another aspect, a count of the higher state memory cells which exceeds the initial or final verify voltage is used to determine when to begin verify tests for the higher data state. The counted memory cells are not subject to the reduced programming speed. |
