SoC security is taking center stage as more interfaces are used to process, store, and connect large amounts of valuable data at increasingly faster rates. More connected devices, more sophisticated attacks, and more regulations for data privacy and protection require strict security for SoCs and data communication. This demands the semiconductor industry to take a serious look at security, not as an afterthought but as an essential part of SoC development. Interfaces need to incorporate security to ensure data confidentiality and integrity. This can be achieved by encryption/decryption, authentication, and physical protection. Integrating security features in the controllers, Synopsys offers a broad range of secure interface IP products to protect HPC, IoT, mobile, and automotive SoCs against tampering and physical attacks.
