A method of facilitating an anonymous message board may include receiving a secret key share associated with a published public key. An initial table state may be generated by encrypting, via the public key, an initial table including a table index and table initial values. A user post encrypted via the public key may be received, the user post including a message and a message index value. The initial table state may be updated to an updated table state by replacing an initial table value of the initial table values with the message. In response to a time interval associated with a predetermined length of time expiring after generating the initial table state, the updated table state may be partially decrypted via the first secret key share as a partially decrypted table. The partially decrypted table may be broadcast.

Methods, systems, and devices relate to digital wireless communication, and more specifically, to techniques relating to dynamic change MAC address of the station for subsequent transmissions. In one exemplary aspect, a method of dynamic change MAC address includes specifying a MAC address change mode and a new MAC address to be used by the station. In another exemplary aspect, a method of dual MAC address change mode in the dynamic change MAC address mechanism includes separating the unchanged MAC address of the station from the changeable MAC address of the station, and keep the mapping between them. In another exemplary aspect, a method includes transmitting a MAC address change request message from the station (or the access point) to initiate the MAC address change procedure. In another exemplary aspect, a method includes receiving a MAC address change response message from the access point (or the station).

A method for deriving a partial signature for a subset of a set of messages. The method is implemented by a partial signature derivation entity and includes: receiving the set of messages and a signature of the set of messages, the signature including signature elements of the set of messages; deriving a first verification element calculated from the messages of the set other than those of the subset; deriving a second verification element to prove that the first verification element is formed correctly; and sending to a verification entity a partial signature specific to the subset, the partial signature including a constant number of elements having at least the elements of the signature of the set of messages, the first verification element and the second verification element, the partial signature being verifiable with only messages of the subset.

The present invention provides a wireless communication method of an access point. The wireless communication method comprises the steps of: establishing a cache table comprising a plurality of reference MAC and corresponding PMKs and reference PMKIDs; receiving an association request from a station; reading a MAC address of the station and a PMKID from the association request; if the MAC address of the station and the PMKID do not match items of the cache table, performing a calculation on the PMKID to obtain an original PMKID; determining if the original PMKID matches any one of the reference PMKIDs within the cache table; and if the original PMKID matches one reference PMKID within the cache table, determining that the reference MAC recorded in the cache table and the MAC address belong to the same station.

The technical problem of matching records in different datasets, for example a host dataset and a partner dataset storing records representing respective users, while maintaining the privacy of each dataset, is addressed by providing a privacy safe joint identification protocol. The privacy safe joint identification protocol computes respective anonymous joint identifiers for records in the two datasets. An anonymous joint identifier is generated such that the host-assigned and the partner-assigned identifies that have been determined to represent the same user are mapped to the same anonymous joint identifier.

Data can be automatically anonymized in a distributed storage system. For example, a system can receive a notification indicating that an object is stored in a non-persistent bucket of a distributed storage system. The system can read the object from the non-persistent bucket in response to receiving the notification. The system can generate an anonymized version of the object by performing one or more anonymization operations with respect to the object. The system can store the anonymized version of the object in a persistent bucket of the distributed storage system. The system can then transmit a command for causing the object to be removed from the non-persistent bucket.

Performance of devices can be evaluated and enhanced in software-defined systems. For example, a computing device can receive, at a server of a software-defined system, a first plurality of properties describing a client system in the software-defined system. The computing device can compare, by the server, the first plurality of properties to additional properties describing at least one additional client system in the software-defined system. The computing device can determine, by the server, an adjustment for the client system based on the comparison and a similarity of the client system to each of the at least one additional client system. The computing device can output, by the server, an indication of the adjustment to the client system.

A cybersecurity infection detection system and method of use. In some embodiments, the system and process provide improved network security, computer security, or both, through mutually assured, defense in depth approaches. In some embodiments, one or more of defense in depth, collaborative attack detection, remediation, component redundancy, component self-monitoring, and component self-replacing are combined to effect an enhanced cybersecurity system. In some embodiments, the cybersecurity system and method include, but are not limited to, one or more of one or more probes, monitors, configuration ledgers, signature ledgers, audit ledgers, configuration controllers, message engines, switchboards, and a public-private key infrastructure.

A system for vaultless tokenization and encryption includes an iframe service for collecting data and a tokenization service for (de)tokenizing and encrypting/decrypting data. The system is accessible to users and partners that submit requests causing various functions to be executed by the system. The functions include, but are not limited to, providing (de)tokenization and/or encryption services, and managing and creating templates for iframe collection, (de)tokenization, and encryption/decryption. A template service facilitates generation of templates that parametrize collection of original data via served iframe elements, tokenization and/or encryption of original data, and detokenizing and/or decrypting tokens to recover original data. An iframe service is configured for providing a virtual terminal, an iframe that provides users direct access to (de)tokenization and/or decryption/encryption services. Access to system services is managed via identifiers that include authentication credentials and parameters for performing (de)tokenization and/or encryption/decryption processes.

Preserving user privacy and preventing surveillance on behalf of users of a virtual reality world. One or more plans are available when a privacy or surveillance risk to a user is detected. In one plan, configurable scripts execute on behalf of the user to create a confusing array of clone avatars that obfuscate the real user avatar behavior. A malevolent avatar, attempting to surveil the user, may have difficulty distinguishing the clones from the user and may miss out on private insights he might otherwise have learned from the user's behavior. In another exemplary privacy plan, a copy of part of the virtual world is spawned, occupied exclusively by the user's avatar, and then merged into the main world. Privacy plans may be selected manually or automatically in response to perceived privacy threats to strike a balance between privacy and enjoyment within the virtual world.
