In encryption, a key is the information used to encrypt the data. 128 bit means that the key is 128 bits long (a bit is a single unit, or "bit" of data, either 0 or 1). The longer the key, the more complex the encrypted data becomes. 128 bits is considered a strong key length.

What is difference between WEP 64 and WEP 128?
The 64 bit WEP key uses a 40 bit (10 Hex character) Encryption and a128 bit WEP key uses a 104 bit (26 Hex Character) Encryption.So the 128 bit WEP key is a higher level of encryption compared to 64 bit WEP.
How does the encryption process work with a 48-bit key?
Encryption with a 48-bit key involves using a specific algorithm to scramble the data into a code that can only be deciphered with the correct key. The key, which is 48 bits long, determines how the data is encrypted and decrypted. The longer the key, the more secure the encryption, as there are more possible combinations to crack.
Public key encryption is also known as asymmetric encryption?
Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
Symmetric encryption involves what key?
A shared secret keyand other words;Both the sender and receiver share the same key
What is a 64 bit encryption?
Answer: Data encryption is the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. Historically, data encryption has been used primarily to protect diplomatic and military secrets from foreign governments. It is also now used increasingly by the financial industry to protect money transfers, by merchants to protect credit-card information in electronic commerce, and by corporations to secure sensitive communications of proprietary information. Encryption systems are often grouped into families. Common families include symmetric systems (e.g. AES) and asymmetric systems (e.g. RSA), or may be grouped according to the central algorithm used (e.g. elliptic curve cryptography). As each of these is of a different level of cryptographic complexity, it is usual to have different key sizes for the same level of security, depending upon the algorithm used. For example, the security available with a 1024-bit key using asymmetric RSA is considered approximately equal in security to an 80-bit key in a symmetric algorithm (Source: RSA Security). The actual degree of security achieved over time varies, as more computational power and more powerful mathematical analytic methods become available. For this reason cryptologists tend to look at indicators that an algorithm or key length shows signs of potential vulnerability, to move to longer key sizes or more difficult algorithms. For example as of May 2007, a 1039 bit integer was factored, with the special number field sieve using 400 computers over 11 months. The factored number was of a special form; the special number field sieve cannot be used on RSA keys. The computation is roughly equivalent to breaking a 700 bit RSA key. However, this might be an advanced warning that 1024 bit RSA used in secure online commerce should be deprecated, since they may become breakable in the near future. Cryptography professor Arjen Lenstra observed that "Last time, it took nine years for us to generalize from a special to a non-special, hard-to-factor number" and when asked whether 1024-bit RSA keys are dead, said: "The answer to that question is an unqualified yes 64 bit encryption indicates that the size of the key used to encrypt the messageis 64 bits. The 64-bit encryption standard was used in some early Internet and wireless communication encryption algorithms such as DES and WEP. Unfortunately, 64-bit encryption has proven too easy to decipher or crack in practice. Now, 128-bit encryption (in 3DES or TDES) have replaced the 64-bit encryption keys (DES).
Which type of encryption key should be enabled on WPA-compliant devices?
128 bit key.
What is difference between WEP 64 and WEP 128?
The 64 bit WEP key uses a 40 bit (10 Hex character) Encryption and a128 bit WEP key uses a 104 bit (26 Hex Character) Encryption.So the 128 bit WEP key is a higher level of encryption compared to 64 bit WEP.
What is the difference between WEP64 and WEP128?
WEP64 uses a 64-bit encryption key, and WEP128 uses a 128-bit key.
How many characters in a 256bit wep key?
It depends on the encryption strength. For 64 bit connections, the key is 10 digits long. For 128 bit connections, the key is 26 digits long. For 256 bit connections, the key is 58 digits long.

Which algorithm has the smallest key space?
DES Data Encryption Standard 56 bit
How many characters are used in a 64 bit WEP encryption key?
10 characters
Using a 20-bit key is how many times more secure than using a 18-bit key?
four times. adding 1 bit to an encryption key makes it twice as hard to crack.

What kind of encryption is used with 802.11n?
WEP is kind of old so I'm guessing WPA or WPA2MooseThe original standard released in 1999 was WEP. WEP uses the stream cipher RC4 for confidentiality. Exploitable weaknesses in this protocol prompted the development of WPA.WPA was introduced as an interim solution while the 802.11i standard was developed. WPA added Temporal Key Integrity Protocol (TKIP) to WEP. TKIP encryption replaces WEP's 40-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP is a 128-bit per-packet key, meaning that it dynamically generates a new key for each packet and thus prevents collisions.WPA2 - also known as IEEE 802.11i-2004 replaced the TKIP encryption protocol of WPA with CCMP to provide additional security. CCMP is an AES-based encryption mechanism that is stronger than TKIP. (CCMP is sometimes referred to simply as AES instead of CCMP.) Equipment developed under 802.11i was backwards compatible with earlier equipment and supported the use of WPA and WEP.802.11n requires AES encryption to be enabled on WLANs used by 802.11n clients.
What is the significance of the keyword "t 40 bit" in the context of encryption and data security?
The keyword "t 40 bit" refers to a type of encryption key size that is considered weak and vulnerable to cyber attacks. In the context of encryption and data security, using a "t 40 bit" key can make it easier for hackers to decrypt sensitive information, compromising the security of the data. It is important to use stronger encryption methods with longer key sizes to better protect data from unauthorized access.
What is the average key size of a strong encryption system in use today?
Web-based SSL has standardized on 128 bits as of late 2004
