What is the difference between advanced encryption algorithm and encryption algorithm?
People have developed many encryption algorithms. One particular encryption algorithm is the Rijndael algorithm, usually called the AES or Advanced Encryption Standard.
Which encryption algorithm is better and why?
If you're talking about symmetric key encryption (the kind where you just use one key for encryption and decryption), then arguably, the best encryption algorithm you can use is the Rijndael algorithm, better known now as AES (advanced encryption standard). It is the encryption standard used by the U.S. government for classified information. It is fast, requires little memory, and the only potential attacks against it are highly theoretical. Rijndael beat out Twofish and Serpent in the AES standard contest, but those other two algorithms will provide more than enough security as well. In the end, it doesn't really matter, since most successful attacks are made simply by finding out your key through brute force, espionage or extortion, rather than pure data analysis. Humans are almost always the weakest point when it comes to security, and it doesn't matter what algorithm you use if someone can guess your password.

What is advanced encryption standard?
AES is an encryption algorithm that is largely used in a lot of places where security is a must. The algorithm is based on Rijndael (named after the creators) which had the winning design when the US government sent out an invite for people to create secure algorithms that would replace DES.

What does aes encryption stand for?
AES is an acronym for Advanced Encryption Standard. AES is a variation of Rijndael. Is it used for encryption of electronic data and was established by NIST in 2001.

What is difference between aes and rijndael?
in aes block size fixed i.e.128 bits where as in rsa it is not fixed
How many bit keys do need for a strong encryption?
It depends on the cipher you're using. For AES, the minimum is 128-bit (or 16-bytes) where as the maximum is 256 or 512 (depends on the implementation you're using - AES or Rijndael [from which AES was selected to become the AES standard by the US government]). Another thing to consider is the block-chaining mode and the hashing algorithm. It's generally recognized that ECB and SHA-1 are no longer secure (but still okay for using as a RNG), while SHA-256 hashes and debatably CBC and XTS.
Which cryptography should be use to encrypt the data for an online service provider if the liability is the number one consideration?
Probably the best choice would be to use AES (Advanced Encryption Standard) encryption with a 256 bit key size. There are actually at least 3 different key sizes that can be used with AES - 128, 192, and 256 bits. The longer keys require a little more computational overhead but are more secure. The AES ciphers have been analyzed extensively and are now used worldwide. AES was announced by NIST as U.S. Federal Information Protection Standard (FIPS) Publication 197 (FIPS 197) on November 26, 2001 after a 5-year standardization process in which fifteen competing designs were presented and evaluated before one was chosen to become "AES". The actual cipher chosen by NIST to be publicised under the appellation of AES was the Rijndael cipher submitted by two Belgian cryptographers, Joan Daemen and Vincent Rijmen. It became effective as a Federal government standard on May 26, 2002 after approval by the Secretary of Commerce. It is available in many different encryption packages. AES is the first publicly accessible and open cipher approved by the NSA for top secret information. AES can be implemented in software, but it also lends itself to hardware implementations. AES encryption chips allow much faster encryption of data since all the steps of the encryption are hardwired into the chip. The chips are not horribly expensive and the performance improvement versus software implementations of AES can make the price worth it.
Why pgp compresses massages?
PGP does not compress messages. It encrypts them. PGP is used to ensure that confidential emails to do fall into the wrong hands, and that a message is in fact from the person you think it is.• Developed by Phil Zimmerman in 1995.• Documentation and source code is freely available.• The package is independent of operating system and processor.• PGP does not rely on the "establishment" and it's popularity and use have grown extensively since 1995.• PGP combines the best available cryptographic algorithms to achieve secure e-mail communication. • It is assumed that all users are using public key cryptography and have generated a private/public key pair.• Either RSA (with RSA digital signatures) or El Gamel (with DSA) can be used.• All users also use a symmetric key system such as triple DES or Rijndael.
What has the author Kenneth P Goldberg written?
Kenneth P. Goldberg is an author known for his books relating to technology and security, such as "The Design of Rijndael: AES - The Advanced Encryption Standard" and "Defensive Security Handbook: Best Practices for Securing Infrastructure".
Aes is considered more secure than des and triple des because?
Well because it's the newest. DES has been around since 1973 but wasn't formally a federal standard until 1976. It had to recertify every 5 years, the probem with this was....No company's came forth to go against the standard. So 30 years go by and tons of people have found ways to decipher DES. Weak keys are a major problem, and there are only a certain amount of keys allowed due to it's bit size. 2^56 keys available. It's susceptable to brute force attacks. 3DES goes through 3 rounds of DES, but it still has the same weaknesses. After 30 years of the standard, NIST called for a new standard the AES, it went with a contest design. There were 5 finalist. MARS by IBM, RC6 by RSA, Rijndael by John Daemen and Vincent Rigmen, Serpent by Ross Anderson, Eli Biham, and Lars Knudsen, and Twofish by Bruce Schneier, John Kelsey, Doug Whiting, David Wagner, Chris Hall, and Niels Fergson. The winner was Rigndael which was chosen in 2000. The competition called for a block cipher using symmetric Key cryptography. It also had to support key sizes of 128, 192 and 256 bits. For big and small devices. It standardizes at 128 bits blocks. the size of the key depends on the number of rounds of encrpytion. Wikipedia it to find out more about how the new standard works. Since it has 3 different sizes, brute force attack with current systems would take a really long time. But as technology grows so will the need for an even stronger crypto system. 3AES may be the next standard :)
