  • Patent number: 12261931
    Abstract: A system and method for provisioning confidential data such as unique credentials is described. The technique initializes a whitebox cryptographic software module to a particular PKI client to soft-lock whitebox cryptographic operations to the particular PKI client and uniquely encrypting the credentials with a node-locking key (NLK) derivable from a digital certificate.
    Type: Grant

  • Publication number: 20230198781
    Abstract: A method and apparatus for securely generating an output is disclosed. In one embodiment, the method comprises generating a white-box implementation having unlocked white-box look up table (LUTs) for node-encoded secrets, the node-encoded secrets to be encoded for operation solely on a node of a network and globally encoded white-box LUTs for globally-encoded secrets to be encoded for operation on the node and at least another node; generating, from the white box implementation, a soft-locked white-box implementation having a plurality of node-specific locked white-box LUTs and modified globally encoded LUTs. The method further comprises receiving a global secret encoded according to the base file; generating the node-encoded secrets by applying node-specific locking transformations to the global secret; and generating, by the node, the output according to at least one of the globally-encoded secrets or the node-encoded secrets.
