Claim 24:
25. A non-transitory computer readable media having computer-executable instructions embodied therein that, when executed by a processor of a computing system, cause the computing system to perform operations comprising:
transmitting a hash-based message authentication code (HMAC) key cryptogram and a transaction scheme to a database encryption key management system;
receiving a seed generated by the database encryption key management system based on the HMAC key cryptogram and the transaction scheme;
decrypting the seed; and
based on the seed, deriving a transaction key (Tk);
causing the database encryption key management system to determine that a second entity computing system has been whitelisted to use the transaction scheme; and
causing the database encryption key management system to transmit the seed to the second entity computing system for derivation of the Tk by the second entity computing system based on the seed.
