MMS (Manufacturing Message Specification) doesn't inherently include built-in encryption mechanisms, unlike some other protocols such as XMPP (Extensible Messaging and Presence Protocol) that may have encryption capabilities as part of their standard implementations.

When implementing security measures like encryption, authentication, and data integrity protocols in MMS, it often requires additional configurations or layers such as TLS (Transport Layer Security) to secure the communication channel.

As a result, when comparing the baseline without security measures, MMS might experience a more noticeable increase in latency after applying security mechanisms like encryption. Adding encryption to MMS would involve additional processing overhead for encryption and decryption of data packets, potentially leading to higher latency compared to a protocol like XMPP, which might have inherent security features or easier integration with encryption protocols.

However, the precise impact on latency depends on various factors, including the strength of encryption, hardware capabilities, network conditions, and the efficiency of the security implementation within each protocol. Efficient implementation and optimization of security measures in both protocols can help minimize latency impacts while ensuring secure communication.
