  • Patent number: 11115395
    Abstract: A cross-domain information transfer system includes a key distribution center that generates private encryption keys and a signature key pair as a secret signing and secret verifying key for an attribute associated with a given domain. A sender device generates ciphertext from plaintext based upon the private encryption key, appends an attribute for a given domain to the ciphertext, generates ciphertext with a concealed attribute based upon the secret signing key and broadcasts the ciphertext with the concealed attribute. Domain gateway devices each receive a respective secret verifying key for an associated attribute, receive the ciphertext with the concealed attribute from the untrusted network, and use the secret verifying key to determine if the concealed attribute matches the attribute associated with the domain gateway device, and, when so, pass the ciphertext to at least one receiver device coupled with the domain gateway device.

  • Patent number: 10666437
    Abstract: Systems (100) and methods (700) for customizing a cryptographic algorithm. The methods comprise: providing an electronic device with the cryptographic algorithm implementing a permutation function ƒ configured to produce a first keystream using bits input thereto, the permutation function ƒ comprising a round function ƒround consisting of a mixing layer in which input bits are combined together; and customizing the mixing layer of the permutation function ƒ while the electronic device is in the field. The mixing layer is customized by: receiving, by the electronic device, a first user-software interaction for entering a first bit string comprising a plurality of first arbitrary bits; breaking the first bit string into a plurality of equal length segments each comprising only a portion of the plurality of first bits; and translating each of the equal length segments into irreducible polynomial coefficients and/or an irreducible polynomial identifier.
