Question

Which technology can be used to protect voip against eavesdropping??

Answer 1

Answer:

VOIP is carried over a transport layer protocol. Any encrypted transport layer protocol thus will encrypt a VOIP call. Of course, both ends of the call must agree on the encryption to be used.

Answer 2

Answer:

The technology used to protect VoIP against eavesdropping is found to be: Encryption (end to end).

Explanation:

• Encryption is a method of converting information  into a secret code that hides the  true meaning of the information. The science of information encryption and decryption is called encryption.
• In computing, un-encrypted data is also called plain text, and encrypted data is also called cipher text. The expressions used to encode and decode messages are called cryptographic algorithms or ciphers.
• To be effective, the cipher contains variables as part of the algorithm. A variable called a key makes the output of the cipher unique. If an encrypted message is intercepted by an unauthorized entity, the intruder must guess the cipher used by the sender  to encrypt the message and the key used as a variable. The time and difficulty of guessing this information is why cryptography has become such a valuable security tool.
• Encryption has long been a  way to protect sensitive information. Historically, it has been used by military and government officials. Today, encryption is used to protect data stored on computers and storage devices, as well as data transferred over networks.
