Summary:Disclosed systems and techniques include a cryptographic processor for processing of both unprotected data and protected data using an unprotected data path. In one implementation, the cryptographic processor includes a processing unit, and a control unit to selectively cause the processing unit to operate in a public mode or a secure mode. In the public mode, the processing unit performs a computational operation to compute a nonlinear function of a public data. In the secure mode, the processing unit computes, over a plurality of iterations, a plurality of shares of the nonlinear function of a secure data. At each iteration, the processing unit performs multiple instances of the computational operation to compute a respective share of the nonlinear function of the secure data.
