Reconfigurable secure input device

摘要

A reconfigurable secure input device (RSID) receives an encryption key and at least one transformation instruction. The RSID stores the encryption key in a memory section. The RSID stores the at least one transformation instruction in a second memory section. A RSID processor utilizes the at least one transformation instruction to create a plurality of transformed codes. The plurality of transformed codes along with a plurality of values corresponding to each of the plurality of potential actual input device inputs are both stored in a transformed lookup table. The RSID processor receives an actual input device input. The RSID processor matches the actual input device input with one of the plurality of the potential keyboard inputs to create a matching value. The RSID processor outputs a matching transformed code from the transformed lookup table corresponding to the matching value.
