brp_mutual_authenticate()

BRP_LIB brp_errcode brp_mutual_authenticate	(	brp_protocol	protocol,
		int	security_level,
		brp_sec_key	key,
		int *	req_auth_modes,
		brp_sec_key	session_key
	)

Does a mutual authentication and generates a session key.

This command is only for low-level usage. Instead of using it, it is recommended to use the high-level wrapper brp_create_secure_channel()

This lowlevel operation is usually used only internally by brp_create_crypto() and is not needed by end users.

Parameters

protocol	device against which the library shall authenticate
security_level	security level that shall be authenticated
key	the key that shall be used to establish a secure channel
req_auth_modes	a bitmask of auth modes that are required
session_key	session key that can be used by brp_secured_exec_cmd(). Maybe NULL, if sessionkey is not needed.
