Cryptographic MCU delivers turnkey security for connected devices

November 29, 2016 // By Julien Happich
Designed to meet Common Criteria EAL4+ requirements, Maxim’s cryptographic controller MAXQ1061 integrates a comprehensive cryptographic toolbox that provides full support for a wide spectrum of security needs, ranging from key generation and storage, to digital signature and encryption up to SSL/TLS/DTLS.

It can also support secure boot for most host processors. The MAXQ1061 embeds 32KB of user programmable secure EEPROM for storing certificates, public keys, private and secret keys, and arbitrary user data. The EEPROM is managed through a flexible filesystem enabling custom security policy enforcement. Its cryptographic algorithms include ECC (up to NIST P-521), ECDSA signature generation and verification, SHA-2 (up to SHA-512) secure hash, AES-128/-256 with support for ECB, CBC, and CCM modes, and MAC digest. The MAXQ1061 also provides a separate hardware AES engine over SPI, supporting AES-GCM and AES-ECB modes, and that can be used to off-load a host processor for fast stream encryption. To withstand extreme industrial environments, the MAXQ1061 operates across the -40º to +109ºC temperature range, it comes in a TSSOP-14.
