The SoCs of this disclosure concurrently operate multi-round encryption and decryption datapaths according to a combined sequence of encryption rounds and decryption rounds. An example SoC of this disclosure includes an engine configured to encrypt transmission (Tx) channel data using a multi-round encryption datapath, and to decrypt encrypted received (Rx) channel data using a multi-round decryption datapath. The SoC further includes a security processor configured to multiplex the multi-round encryption datapath against the multi-round decryption datapath on a round-by-round basis to generate a mixed sequence of encryption rounds and decryption rounds, and to control the engine to encrypt the Tx channel data and decrypt the encrypted Rx channel data according to the mixed sequence of encryption rounds and decryption rounds."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Swapping of encryption and decryption operations for side channel attack protection","description":"This disclosure describes systems on a chip (SOCs) that prevent side channel attacks (SCAs).
