The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. government computer security standard. It is commonly referred to as FIPS 140-2 and is used to accredit the design and implementation of cryptographic modules. A cryptographic module within a security system is necessary to maintain the confidentiality and integrity of the information protected by the device.

The security engines of the CC3235x device are FIPS validated for FIPS 140-2 level 1 certification ⁽¹²⁾. This certification involves testing the device for all areas related to the secure design and implementation of the cryptographic modules and covers topics such as: cryptographic specifications, ports and interfaces, a finite state model for the cryptographic module, the operational environment of the module, and how cryptographic keys are managed.
