    Abstract: A system described herein provide for the secure maintaining and providing of information, such as public keys used in Public Key Infrastructure (“PKI”) techniques or other techniques, using a secure distributed ledger (e.g., “blockchain”) system. A blockchain system may be utilized in lieu of a key escrow system in the exchange and/or providing of public keys in a Diffie-Hellman key exchange technique or other type of technique in which public keys are provided from one entity to another. A first entity may generate an asymmetric key pair that includes a public key and a private key, and may provide the public key to a blockchain system for retrieval by one or more other entities. For example, the entities may be engaged in a secure messaging session, in which messages are encrypted and may be decrypted using one or more keys, including the public key.

    Abstract: A first user device may provide, to a provisioning device, a request for a subscriber identity module (SIM) swap that causes provisioning data to be provided to a first SIM card of the first user device and from a second SIM card of a second user device. The first user device may generate a first encrypted token based on a first identifier associated with the first SIM card. The first user device may provide, to the provisioning device, the first encrypted token and a user identifier. The first user device may selectively receive the provisioning data when the first encrypted token matches a second encrypted token generated by the second user device based on a second identifier associated with the second SIM card, or receive a message indicating that the first user device cannot be provisioned, when the first encrypted token fails to match the second encrypted token.

    Abstract: One or more computing devices, systems, and/or methods for data fragmentation and reconstruction are provided. Random number generation information, indicating a number of fragments into which data stored by a client device is to be fragmented, is received. The data is fragmented according to the number of fragments as a set of fragments. Authentication data is incorporated with the set of fragments. A set of entities capable of storing the set of fragments with the authentication data is identified. The set of fragments with the authentication data are stored across the set of entities.
