WEP vs WPA vs WPA2 | Difference between WEP,WPA,WPA2This page compares WEP vs WPA vs WPA2 and mentions difference between WEP, WPA and WPA2.It describes WEP encryption and WEP decryption block diagram, mentions WEP drawbacks and 802.1x authentication used in WPA.It provides link to AES encryption used in WPA2 algorithm.Wireless security has been a concern since long due to open air transmission medium used by it.Inspite of many security mechanisms incorporated in wireless, it can never be 100% secure mode ofdata transmission. There are various wireless networks based on different standard based technologiessuch as zigbee, GSM, WLAN, Zwave, bluetooth etc. WEP, WPA and WPA2 are encryption algorithms used in WLAN wirelessnetwork or wifi network.WEP Encryption and WEP DecryptionFollowing are the features of WEP (Wired Equivalent Privacy): • WEP is symmetric as same keys are used for encryption and decryption. • It uses 40 bit key for encryption (non-standard versions can use 128 bit or 256 bit) and 24 bit pattern for IV (Initialization Vector). • It uses RC4 stream cipher to provide confidentiality and CRC polynomial of 32 bit size for data integrity. • The WEP encryption and WEP decryption process uses simple XOR as explained below. Figure:1 WEP Encryption Process Block DiagramThe fig-1 depicts WEP encryption procedure.There are two processes being applied to plaintext in WEP.One process encrypts the plaintext while the other protects the data from any modification by intruders.Following are the steps involved in WEP encryption process: • Encrypt the plaintext using 64 bit key. Here 64 total bits consists of 40 bit secret key and 24 bitinitialization vector (IV). • As shown RC4 uses key value as initial seed and generates PN key sequence. • The PN key sequence is XORed with data. The resulting encrypted bytes have same length as input data bytes. • The 4 bytes IV value is added with ciphertext before transmission. • RC4 algorithm is applied on plain text, ICV and key sequence in order to generate cipher text.This is done to prevent data modification by unauthorized person. Figure:2 WEP Decryption Process Block DiagramFollowing are the steps involved in WEP decryption process: • IV value from incoming message is used to generate key sequence.It is used to decrypt the incoming message. • RC4 algorithm is applied to cipher text with key sequence to produce originalplaintext as well as ICV. • New ICV is determined based on received plaintext. • The algorithm is verified for correctness by comparing new ICV with the one decoded from received data. • If both new ICV and decoded matches received message is considered to be correct otherwiseit will be discarded. Drawbacks of WEP Encryption AlgorithmFollowing are the drawbacks of WEP encryption: • Analysis of captured traffic

SSID without PMF being enabled.A transition mode exists to allow WPA3 clients to use PMF while WPA2 clients can still connect. WPA transition mode basically downgrades the security of your SSID to a regular WPA2 SSID though.Fast Transition (FT), the standard for fast and secure roaming (covered in more detail in the next chapter, along with client mobility), is not supported with 192-bit WPA3 Enterprise at this time; this would need a new AKM for 192 bits + FT and would need clients to support it, so it’s an industrywide limitation. Also, Catalyst 9115 and 9120 access points do not support WPA3 SuiteB GCMP256 ciphers (AES256 is okay).Preshared Key for WPA PersonalWhen you’re configuring WPA Personal with a preshared key, what you typically think of as “the key” is actually the passphrase. It is not what is used to encrypt the traffic and not even what is used to generate the actual encryption key. Details are beyond the scope of this book, but the passphrase is converted to a 256-bit key, called a Pairwise Master Key (PMK), using a standard conversion method. That 256-bit key is used to generate the actual final encryption key. This allows you to have a variable-length passphrase (imagine having to remember a 64-character passphrase, for example), which is easier to remember. The requirements for the passphrase are that it must contain between 8 and 63 printable ASCII characters. Eight characters is really not a lot and should definitely not be used in production because it is a reasonable length to brute-force by using dictionaries of commonly used passphrases. Using a longer passphrase (including fancier characters) randomizes the 256-bit final key better and protects you from brute-force attacks.One of the inherent weaknesses of the PSK authentication and key management protocol is that even if the encryption/session

The WPA Encryption Key Generator is an essential tool for enhancing the security of your wireless network. It specializes in creating a robust encryption key tailored to your WiFi, ensuring your network remains protected from unauthorized access. This tool is particularly user-friendly, as it allows you to generate a key that can be effortlessly copied and pasted into your wireless router’s configuration panel.Understanding the Evolution of Wireless Security: Wi-Fi Protected Access (WPA) and its successor, WPA2, were developed in response to vulnerabilities discovered in earlier wireless security protocols like WEP (Wired Equivalent Privacy). WPA represented a significant step forward in implementing IEEE 802.111 standards, which are crucial for maintaining the integrity and security of wireless networks.Compatibility Considerations: WPA was engineered to work seamlessly with wireless network interface cards. However, it encountered some compatibility issues with the first generation of wireless access points. On the other hand, WPA2 boasts full standard implementation properties, offering a more robust security framework. It’s important to note, though, that WPA2 might face compatibility challenges with older network cards.Versatility in Security Levels: Our WPA Encryption Key Generator offers flexibility in security levels, catering to different needs and preferences. These include:Maximum Security: This level generates a key comprising 63 characters (504 bits), offering the highest level of encryption and security for your network. Ideal for environments where data sensitivity is high.Minimum Security: Providing a balance between security and ease of use, this level creates a 20-character (160-bit) key. It’s suitable for less critical applications where convenience is a priority.Light Security: With an 8-character (64-bit) key, this level is designed for situations where basic security is needed without the complexity of longer keys.Custom Size: This flexible option allows you to specify a key length anywhere between 8 and 63 characters, giving you control over the security level and
