Secure distribution and management of cryptographic keys within a computing environment using distributed ledgers

An apparatus, comprising:

• a communications interface;
• a memory storing instructions;
• and
• at least one processor coupled to the communications interface and the memory, the at least one processor being configured to execute the instructions to:
• receive, from a device via the communications interface, a request and a first digital signature, the first digital signature being applied to the request, the request comprising a public cryptographic key and a first digital token, and the first digital token being indicative of a prior authentication associated with the device;
• based on a validation of the first digital signature and of the first digital token, and based on a determination that the first digital token corresponds to a second digital token associated with the device, approve the request and apply a second digital signature to the request and the first digital signature;
• and
• transmit, via the communications interface, the request, the first digital signature, and the second digital signature to a computing system, the computing system performing operations that record the public cryptographic key within an element of a distributed ledger.

A computer-implemented method, comprising:

• receiving, using at least one processor, a request and a first digital signature from a device, the first digital signature being applied to the request, the request comprising a public cryptographic key and a first digital token, the first digital token being indicative of a prior authentication associated with the device;
• based on a validation of the first digital signature and of the first digital token, and based on a determination that the first digital token corresponds to a second digital token associated with the device, performing operations, using the at least one processor, that approve the request and apply a second digital signature to the request and the first digital signature;
• and
• transmitting, using the at least one processor, the request, the first digital signature, and the second digital signature to a computing system, the computing system performing operations that record the public cryptographic key within an element of a distributed ledger.

• receive, from a computing system via the communications interface, a request, a first digital signature applied to the request, and a second digital signature applied to the request and to the first digital signature, the request comprising a first public cryptographic key associated with a device, a digital token, and a first code challenge, and the second digital signature being indicative of a prior approval of the request by the computing system;
• validate the first digital signature using the first public cryptographic key, and validate the second digital signature using a second public cryptographic key of the computing system;
• and
• based on the validation of the first and second digital signatures, based on a validation of the digital token, and based on a determination that the first code challenge corresponds to a second code challenge associated with the device, perform operations that record the first public cryptographic key within an element of a distributed ledger.
