Attestation and enforcement of cryptographic requirements across multiple hops

A system for multi-endpoint cryptographic orchestration, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory, the at least one processor and the at least one memory configured to:
• establish, by a first endpoint of a plurality of endpoints related to a multi-endpoint secure communication session, a metadata channel with one or more other endpoints of the plurality of endpoints;
• send, by the first endpoint, to a second endpoint of the one or more other endpoints, via the metadata channel, an indication of a cryptographic requirement related to the multi-endpoint secure communication session;
• perform, by the second endpoint, one or more cryptographic operations related to the multi-endpoint secure communication session based on the indication of the cryptographic requirement;
• and
• attest, by the second endpoint, via the metadata channel, that the one or more cryptographic operations comply with the cryptographic requirement.

A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• establish, by a first endpoint of a plurality of endpoints related to a multi-endpoint secure communication session, a metadata channel with one or more other endpoints of the plurality of endpoints;
• send, by the first endpoint, to a second endpoint of the one or more other endpoints, via the metadata channel, an indication of a cryptographic requirement related to the multi-endpoint secure communication session;
• perform, by the second endpoint, one or more cryptographic operations related to the multi-endpoint secure communication session based on the indication of the cryptographic requirement;
• and
• attest, by the second endpoint, via the metadata channel, that the one or more cryptographic operations comply with the cryptographic requirement.
