ECC Library Sizes with respect to RAM and Flash memory

[Srinivas V]

Hi Team,

We are planning use the crypto libraries for our application, just we want to know which library is best for us in terms of speed and memory consumption,

1. mbed TLS   for normal crypto functions like AES-ECB, CFB  etc..

2. Micro-Ecc for Ecc functionalities                  

3. OBERON foR Ecc functionalities  - out of these two which will take less RAM and Flash size and which one is faster

Regards,

Hi,

• For AES you would either have to use Mbed TLS or CC310(if you use nRF52840). If you use nRF52840 then I think CC310 would be the better choice based on performance. 
• Don't have data on memory but Oberon has been observed with better performance on ECC functionalities. Note that they offer different types of curves and schemes.
