There was a memory problem in the encryption using snow_3g_f8, so AMF/MME crashed. To solve this problem, we used the snow-3g encryption library created as below. https://github.com/rcatolino/libressl-snow3g However, it seems that this library cannot be used to create integrity hash like snow_3g_f8. So, we decided to keep both snow-3g libraries for the time being. 1. lib/crypt/snow3g* : for INTEGRITY (NIA1, EIA1) 2. lib/crypt/openssl/snow3g* : for ENCRYPTION (NEA1, EEA1)
