LINKCAST data transfer is very fast because it communicates with the encryption protocol using UDP. HTTPS access, which is vulnerable to backdoor attacks, is used only for initial login processing.

In this way the encryption key is changed to a completely new key very frequently, with every individual chat.
This is how LINKCAST protects user privacy in the most effective way possible.

Encryption uses AES 256 bit for ECDHE and encoding for authentication and HMAC - 512 bit for hash.
