Functional objectives of SRTP encryption
In order to limit the risk of security attacks and brazil whatsapp shopping data denial of service, SRTP encryption is used . This encryption has the following objectives:
Message authentication,
confidentiality of information,
protection against forwarding of data packets in applications of different types:
From a single transmitter to a single receiver,
from a single transmitter to multiple receivers.
Thanks to SRTP encryption, adequate protection can be offered in environments that mix wired and wireless networks, since a layer of security is added to communications .
For companies or businesses that use devices such as softphones to establish a connection to the public network, for example, this encryption method allows for completely secure communication.

Internet telephony (VoIP or Voice over IP ) is based on transmission protocols such as:
RTP ( Real–Time Transport Protocol ),
SRTP ( Secure Real–Time Transport Protocol ).
The SRTP protocol was developed by a group of cryptographic experts and published under the standard known as RFC 3711.
The SRTP protocol provides messages with:
