nRF7001 7.2 Stream cipher

[AMO2024]

Hello,

i would be interested in which AES-Ciphermode(ECB,XTS,CBC,GCM) is used for encryption of communication ?

Kind regards

Hi

The nRF700x companion chips supports the encryption on stream cipher of whatever host device it uses, so if your host MCU is an nRF5340 for example, it has Arm TrustZone Cryptocell 312, which supports AES-128 and 256: ECB, CBC, CMAC/CBC-MAC, CTR, CCM/CCM*, GCM for example.

Best regards,

Simon
