|
They make it easy for people to create and implement new encryption methods
|
|
|
They do not make encryption more secure; open standards make it easier for third parties to intercept and decode messages

Detailed explanation-1: -Which of the following explains why open standards make encryption more secure? They are developed and reviewed by committees of experts and adopted by all Internet users. Which encryption method is most widely used and why? Public Key Encryption: this method does not require a secure channel for exchanging keys.
Detailed explanation-2: -Symmetric encryption has a fundamental weakness: the encryption key is itself a message that needs to be send to your friend but not intercepted by your enemy. Public key cryptography is a mathematical technique to avoid the need to communicate a secret key from one person to another.
Detailed explanation-3: -AES encryption One of the most secure encryption types, Advanced Encryption Standard (AES) is used by governments and security organizations as well as everyday businesses for classified communications. AES uses “symmetric” key encryption. Someone on the receiving end of the data will need a key to decode it.
Detailed explanation-4: -Cyber security standards enhance security and contribute to risk management in several important ways. Standards help establish common security requirements and the capabilities needed for secure solutions.
