Abstract:
The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that dynamically generate and manage a distribution of asymmetric cryptographic keys using distributed ledgers. For example, an apparatus may extract, from a hierarchical data structure, an index value associated with a corresponding element of permissioning data. The apparatus may also extract, from a first element of a distributed ledger, cryptographic data that includes a first public cryptographic key associated with the hierarchical data structure. The apparatus may generate a second public cryptographic key based on the first public cryptographic key and the extracted index value, and encrypt information using the second public cryptographic key. The encrypted information may be associated with the corresponding element of permissioning data, and the second public cryptographic key may be discarded in response to the encryption of the information.
