Design and implementation of an encryption chip based on SM3

Abstract： Based on the importance of information security and the demand of local technology, in order to improve the autonomy and control of information security technology, this paper will design a security chip applied in the field of information security. The chip takes the state secret SM3 algorithm as the core of the engine, adopts the single-wire communication method, occupies only one IO communication resource, and the protocol supports the 1-wire bus protocol to meet the needs of different application scenarios. The circuit is based on the domestic commercial 110 nm CMOS process line to complete the circuit design and flow chip manufacturing. The chip layout area is 1.2 mm×1.9 mm, and the communication function of the circuit is normal and stable after the flow test and verification. SM3 algorithm engine is highly efficient and fast, the result shows that the properties of this chip are superior.
