Patent attributes
Systems and methods for securing transaction messages are described. In an example, a rule set may be accessed. The rule set may specify a selection of a key from a plurality of keys or an obfuscation process from a plurality of obfuscation processes. The selection may be based on a condition associated with securing transaction messages. The keys or the obfuscation processes may be stored at a card reader. An instruction about the selection may be provided to the card reader based on the rule set and a determination that the condition is satisfied. In turn, a secure transaction message may be received from the card reader. The secure transaction message may have been secured based on the key or the obfuscation process. The secure transaction message may be provided to a transaction system that includes a management system associated with the key or the obfuscation process.
