IOT security solutions

MAXIM is No.1 security vendor in World Market, MAXIM have MD5、SHA-1、SHA-256、AES、DES、3DES、EC、ECDSA, RSA and all of the Crypto Engine products. MAXIM and AVNET can great support this customer.

The DS28C36 is a DeepCover® secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware implemented crypto engines, the device integrates a FIPS/NIST true random number generator (RNG), 8Kb of secured EEPROM, a decrement-only counter, two pins of configurable GPIO, and a unique 64-bit ROM identification number (ROM ID)
