Integrated, single chip security safeguards IoT data
Two security supervisors from Maxim Integrated offer simple implementation while safeguarding sensitive IoT data, says the company.
The MAX36010 and MAX36011 security supervisors provide tamper detection and cryptography with 60 per cent faster design cycle and 20 per cent lower bill of material costs, claims Maxim.
The supervisors include temperature and voltage sensors, 1kbyte of secure storage, dynamic tamper sensors, real-time clock (RTC), and TRNG—eliminating the need to use multiple discrete components.
They provide IoT device designers a more secure way to protect stored, sensitive information. They are designed 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.
The MAX36010 and MAX36011 can be easily integrated into a design at any stage of its development. If the supervisors are integrated later in the design cycle, there is no need to change the platform to accommodate them, which simplifies the implementation process. To ensure a higher level of security, the supervisors generate keys via a true random number generator (TRNG). These keys are stored in battery-backed RAM along with certificates and other sensitive data. This data is erased when tampering is detected. This 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 both 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 agorithm (ECDSA). These secure cryptographic engines are designed and comply with the requirements of Payment Card Industry (PCI) and FIPS140-2 certifications. The MAX36010 supports symmetric key generation for AES and 3DES, the MAX36011 supports both symmetric and asymmetric key generations for AES, 3DES, RSA and ECDSA.
The MAX36010EVKIT# evaluation kit is also available.
