Abstract
A processor with an elliptic curve cryptographic algorithm and a data processing method thereof are shown. The processor has a first register, storing a public key pointer pointing to a public key. In response to a single elliptic curve cryptographic instruction of an instruction set architecture, the processor reads a plaintext input from a first storage space within a system memory, performing an encryption procedure using the elliptic curve cryptographic algorithm on the plaintext input based on the public key obtained by referring to the first register to encrypt the plaintext input and to generate a ciphertext output, and programming the ciphertext output into a second storage space within the system memory.
