  • Patent number: 11979502
    Abstract: A tracking device can use a permanent encryption key pair to encrypt one or more temporary encryption key pairs, which can then be provided to a central tracking system. When a community mobile device subsequently detects the tracking device, the central tracking system provides an encrypted temporary encryption key pair to the community mobile device. The community mobile device uses the encrypted temporary encryption key pair to encrypt location data representative of a location of the community mobile device, and provides the encrypted location data to the central tracking system. When a user subsequently requests a location of the tracking device from the central tracking system, the central tracking system provides the encrypted location data, and a device of the user can decrypt the encrypted temporary encryption key pair using the permanent encryption key pair, and can decrypt the location data using the decrypted temporary encryption key pair.

  • Patent number: 11977640
    Abstract: Systems and methods are provided for validating components of an Information Handling System (IHS). During factory provisioning of the IHS, an owner certificate is stored that specifies an identity of a motherboard installed during manufacture of the IHS. The owner certificate is signed by a certificate authority of an owner of the IHS that retains capabilities for specifying the use of boot code provided by successive renters of the IHS. A renter certificate is also stored that specifies an identity of a chassis to which the motherboard is installed during manufacture of the IHS. Upon a transfer of control or ownership of the IHS, boot code operations by the security processor identify a motherboard and chassis in use by the IHS and utilize the motherboard and chassis certificates to validate that the identified motherboard and chassis are the same motherboard and chassis installed during manufacture of the IHS.

  • Patent number: 11973765
    Abstract: This disclosure describes techniques for controlling group access to a collaboration technology. The techniques include generating a shared encryption key among authorized producers of content associated with a collaboration technology. The techniques include receiving, by the authorized producers and from authenticated consumers, requests to access the content. The requests may be received in a partitioned manner, such that individual producers are serving a particular subset of the authenticated consumers. In response to receiving the requests, the techniques include sending the shared encryption key from the individual producers to the corresponding subset of authenticated consumers. The techniques include using the shared encryption key to encrypt content by the authorized producers, which may then be decrypted by the authenticated consumers using the shared encryption key, achieving end-to-end encryption of event content.

  • Patent number: 11943350
    Abstract: In certain embodiments, the use of re-usable cold storage keys to sign messages may be facilitated. In some embodiments, an offline computer system (operating within an offline computing environment) may obtain, from a removable computer-readable storage medium, signing key shards corresponding to a signing private key and a blockchain transaction to be signed, where the signing key shards satisfy a key shard threshold that is (i) a number of key shards required for reconstructing the signing private key and (ii) less than a number of key shards derived from the signing private key using a ceremony key. The offline computer system may form a ciphertext of the signing private key using the signing key shards and reconstruct the signing private key by decrypting the ciphertext using the ceremony key. The offline computer system may sign the blockchain transaction using the signing private key.

  • Patent number: 11902253
    Abstract: A method for providing and managing non-direct URL fetching service for retrieving a content from a web server to a client device is disclosed, such as for overcoming geo-blocking or a Man-In-The-Middle (MITM) attack. The non-direct fetching method may use intermediate devices, such as proxy server, Data-Center proxy server, tunnel devices, or any combination thereof. A URL request may be sent in parallel using both direct and non-direct fetching schemes, in order to verify the need for using the non-direct fetching service. Direct or non-direct fetching scheme may be selected by using a file that associates a fetching scheme to the requested URL. The selection of the fetching mechanism may use dynamically in real-time updating of a Proxy Auto-Configuration (PAC) file. As part of an accounting scheme, quotas may be applied to a cumulative received data or a time duration of using a non-direct fetching service.

  • Patent number: 11888974
    Abstract: Various embodiments relate to a method of receiving an original message, share-holder list, and threshold amount. The original message is tokenized resulting in a tokenized message. A plurality of shares are generated from the tokenized message using a message sharing algorithm of a secret sharing scheme. Each of the plurality of shares is signcrypted using a public key and a private key associated with the shared secret provider computing system and a public key of a respective one of the share-holders included in the share-holders list, resulting in a plurality of signcrypted shares. The plurality of signcrypted shares is distributed to the respective ones of the share-holders according to the public key used to signcrypt the respective signcrypted share. The authenticity and data integrity of the first share of the plurality of signcrypted shares can be determined by using the public key associated and a public/private key pair associated with the share-holder.

  • Patent number: 11881939
    Abstract: A system provides for authorization of data access and processing functions within a distributed server network using a delegated proof-of-stake consensus mechanism. In particular, the system may use assign authorization levels to each node within the network environment. Certain actions or processes performed within the network (e.g., potentially damaging actions) may require that the node proposing the action meets a threshold authorization level before authorizing the action. The system may further increase or decrease authorization levels for each node depending on the outcomes of the proposed actions. In this way, the system may provide a secure way to authorize certain actions or processes taken within a computing environment.
