Wireless emergency alert geofencing enhancements
A base station receives an alert indicating a geofenced area, and determines whether its coverage area is completely within the area. If so, the base station generates/sends a wireless emergency alert (WEA) to user equipment in the coverage area that does not indicate the area. Otherwise, the base station generates/sends a WEA that indicates the area. The base station sends action messages that indicate a periodicity and end time for the user equipment to determine whether its location is within the geofenced area, a lack of service time limit and lack of service action for the user equipment to perform after it has been without cellular service for the lack of service time limit, a lack of location time limit and lack of location action for the user equipment to perform if its location cannot be determined for the lack of location time limit, and/or that the WEA has ended. |

Method for detecting anomalies in SSL and/or TLS communications, corresponding device, and computer program product
Described herein is a method and network-security monitoring platform, also identified as Security Network Monitoring Platform (SNMP), for detecting anomalies in SSL and/or TLS communications set up in a communications network.

Next, the SNMP determines for each handshake procedure a first signature as a function of the data sent with the first message and a second signature as a function of the data of one or more certificates of the chain of certificates (CERT) sent with the second message. The SNMP then analyses the first and the second signatures to determine the respective popularity values. Moreover, the SNMP analyses each chain of certificates (CERT) to extract the information that indicates the fact that at least one of the certificates (CERT) of the chain is self-signed, and/or at least one of the certificates (CERT) has expired.During a training step, the SNMP trains a classifier using the popularity values and the information extracted from the certificates (CERT), so that the classifier supplies as output a value that indicates whether a given handshake procedure corresponds to a usual or to an anomalous handshake procedure. Consequently, during operation in steady-state conditions, the SNMP can use the classifier to supply, for each handshake procedure, a respective value that indicates whether the respective handshake procedure corresponds to a usual handshake procedure or to an anomalous handshake procedure and, in the case where at least one handshake procedure has been classified as anomalous, generate a notification that indicates the fact that the respective SSL or TLS communication presents an anomaly. |

Impersonating request-based security in connection-based security environment
A connection-based service impersonates request-based security for requests from clients that do not include credentials for the requests (e.g., data plane requests made via a connection-oriented security). A connection between a client and a connection-based service is established based on connection credentials that are based on security credentials from a request-based security service. The credentials are sent by a security component of the service to a local agent of the remote security service to be authenticated by the security service. An impersonation token is returned by the security service and cached by the local agent. Requests from the client to perform operations do not include credentials. For each request, the service passes an identifier for the client and the operation to a local authorization component that calls the agent for authorization of the requested operation. The agent uses the impersonation token to obtain authorization for the requested operation. |

System and method for extracting data from a compressed and encrypted data stream
A system and method for extracting data from a compressed and encrypted data stream employing lossless compression and a codeword-to-byte mapping enables selective random extraction from compressed and encrypted data. Initially, data is compressed to reduce its size without information loss. A codeword-to-byte mapping table is created, associating codewords with specific positions in the compressed data. When a request for a specific byte range is received, the system uses the mapping to identify the codewords linked to that range within the compressed data. The system then selectively decompresses the identified codewords and subsequently decrypts the decompressed data. This process ensures that only the relevant data is processed, eliminating the need to decompress and decrypt the entire dataset. This approach provides efficient and secure random access to specific data segments within the compressed and encrypted dataset, making it ideal for scenarios requiring selective data retrieval while maintaining data integrity and confidentiality. |

Secondary battery containing an organic polymer electrode additive capable of oxidation-reduction reaction
Inorganic-based lithium mixed electrode materials have a low charge transfer rate and thus have poor fast charging or discharging characteristics. Positive electrode active materials include LCO (lithium cobalt oxide, LiCoO2), NCM (nickel cobalt manganese, Li(NiCoMn)O2), NCA(nickel cobalt aluminum, Li(NiCoAl)O2), LMO(lithium manganese oxide, LiMn2O4), LFP(Lithium iron phosphate, LiFePO4), etc. High nickel technology is attracting attention because if nickel is used a lot, the capacity of lithium ions can be increased. However, as the content of nickel increases, the reactivity increases, resulting in a risk of explosion of the battery and deterioration in cycle life characteristics. As the negative active material, carbon, transition metal oxide, nickel metal, silicon-nickel alloy, and the like may be used. As the carbon, natural graphite, artificial graphite, soft carbon, hard carbon, etc. can be used. As the transition metal oxide, Co3O4, CoO, FeO, NiO, and the like can be used.The present invention adds a polymer additive containing free radicals in the molecular structure to the electrode to solve the problems of the existing secondary battery. The polymer additive contains free radicals and undergoes an oxidation-reduction reaction through ionic interactions. When this polymer additive is included in the electrode, the fast charging and fast discharging characteristics are improved, and the stability of the electrode is improved. When the stability of the electrode is improved, the cycle life characteristics of the electrode are improved. Because the polymer additive participates in the electrochemical reaction, it increases the practical capacity of nickel. When dissolved in a solvent, the polymer additive can increase the viscosity and act as a binder. |
