Abstract: Described herein are systems, methods, and software to manage communications for a network with overlapping IPv4 addressing subnets. In one example, a method of operating a gateway includes receiving a first packet that encapsulates a second packet, the second packet comprising an IPv6 destination address. The method further includes decapsulating the first packet to obtain the second packet, translating the IPv6 destination address to an IPv4 destination address, and communicating the second packet with the IPv4 destination address in place of the IPv6 destination address to a destination computing element.

Abstract: The computer-performed automatic estimation of data leaks from private stores into public stores. The owner of the data in the private store can then be alerted to the estimation so the cause of such leaks can be remedied. The estimation is based on comparisons between similarity mapping results for data within the private store with similarity mapping results for data within the public store. As an example, the one-way similarity mapping could be a fuzzy hashing or a provenance signature.

Abstract: A method of performing tamper-evident logging may include identifying an existing block in a target blockchain, where the existing block is associated with a first signature, and identifying a block of a second blockchain, where the block that is identified is associated with a second signature. The second blockchain is not a part of the target blockchain. The method includes adding a new block to the target blockchain by linking the new block to both the existing block and the block of the second blockchain that is identified by generating a signature for the new block that is based on the first signature and the second signature, and associating the signature with the new block. The target blockchain and the second blockchain may be part of a block lattice.
