Hello Team,

This is a question related to Wi-Fi connectivity and authentication support for the same.
In the web site it mentioned that,
Authentications support as defined in 802.11i:

  • Open
  • WPA (Wi-Fi Protected Access)
  • WPA2 personal and enterprise
  • WPA3 personal and enterprise with 128-bit encryption suite (192-bit encryption not supported)
    Can you please explain the difference between 128bit encryption and 192bit encryption. How does this matter for the connectivity of devices?

Thanks in advance
Dipin

The difference between 128-bit and 192-bit encryption primarily lies in the level of security they provide. Here’s a brief explanation:

  1. 128-bit Encryption:
  • Security Level: Provides a strong level of security that is generally considered sufficient for most applications.
  • Performance: Faster and requires less computational power compared to 192-bit encryption, making it more suitable for devices with limited processing capabilities.
  • Use Case: Commonly used in WPA2 and WPA3 personal and enterprise modes for securing Wi-Fi networks.
  1. 192-bit Encryption:
  • Security Level: Offers a higher level of security than 128-bit encryption, making it more resistant to brute-force attacks.
  • Performance: Slower and requires more computational resources, which can impact the performance of devices, especially those with limited processing power.
  • Use Case: Typically used in environments where higher security is required, but not supported by all devices or networks due to its higher resource demands.

Impact on Connectivity:

  • Devices that support only 128-bit encryption will not be able to connect to networks requiring 192-bit encryption, and vice versa.
  • The choice between 128-bit and 192-bit encryption can affect the performance and battery life of devices, especially those with limited resources.
  • For most consumer applications, 128-bit encryption is sufficient and widely supported, ensuring compatibility across a broad range of devices.

In summary, while 192-bit encryption offers enhanced security, it may not be necessary for all applications and can impact device performance. Most Wi-Fi networks use 128-bit encryption as it balances security and performance effectively.
