An example SoC of this disclosure includes an engine configured to encrypt transmission (Tx) channel data using an encryption operation set configured with a first polynomial, and to decrypt encrypted received (Rx) channel data using a decryption operation set configured with a second polynomial different from the first polynomial. The SoC further includes a security processor configured to multiplex the encryption operation set against the decryption operation set with a varied sequence of selection inputs 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 in a combined datapath 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":"Mixed sequencing of polynomial-diverse encryption and decryption operations for side channel attack protection","description":"This disclosure describes systems on a chip (SOCs) that prevent side channel attacks (SCAs).
