Abstract
Format preserving encryption of floating point data is disclosed. One example is a system including at least one processor and a memory storing instructions executable by the at least one processor to receive floating point data to be secured, where the floating point data comprises a sign bit, exponent bits and fraction bits. A format preserving encryption (FPE) is applied to the received data, where the FPE is applied separately to the sign bit, the exponent bits and the fraction bits to generate an encrypted floating point data comprising an encrypted sign bit, encrypted exponent bits and encrypted fraction bits. The encrypted floating point data is provided to a service provider as a secure representative of the received data.
