Abstract: A single architected instruction to perform scalar multiplication for cryptographic operations is obtained. The instruction is executed, and the executing includes determining a scalar multiply function of a plurality of scalar multiply functions supported by the instruction to be performed. Input for the scalar multiply function is obtained, and the input includes at least one source component and a scalar value. The scalar multiply function is performed using the input to provide an output to be used in a cryptographic operation.
