Maxim Integrated Products’ MAX36010 and MAX36011 single-chip security supervisors offer a smarter and more secure way to protect stored, sensitive information. They are said to make it easier for designers to implement robust tamper detection, cryptography and secure storage while safeguarding sensitive information via logical and physical protections, without having to be security experts themselves.
Both devices offer strong security that can be easily integrated into a design at any stage of its development. Additionally, if these parts are integrated later in the design cycle, there is no need to change the platform to accommodate them. They facilitate a 60% faster design cycle, while also lowering bill of materials (BOM) costs by 20%.
To ensure a higher level of security, the supervisors generate keys via a true random number generator (TRNG). The keys are then stored in battery-backed RAM along with certificates and other sensitive data. This data is erased when tampering is detected, a capability that meets the requirements of Federal Information Processing Standard (FIPS) Publication 140-2 at its highest security levels (Levels 3 and 4).
The MAX36010 and MAX36011 support symmetric and asymmetric cryptographic functions such as Data Encryption Standard (3DES), Advanced Encryption Standard (AES), Rivest–Shamir–Adleman (RSA) and Elliptic Curve Digital Signature Algorithm (ECDSA). These secure cryptographic engines are designed and compliant to the requirements of Payment Card Industry (PCI) and FIPS140-2 certifications. The MAX36010 supports symmetric key generation for AES and 3DES, whereas the MAX36011 supports both symmetric and asymmetric key generations for AES, 3DES, RSA and ECDSA.
