Difference Between Des and Aes (With Table)

Several technical terms are casually used by a lot of people. But not everyone is aware of the original meanings of such terms. People tend to use these terms frequently but, in several cases, they cannot provide any explanation for those terms. DES and AES are two of such terms.

Des vs Aes

The main difference between DES and AES is that the complete format of DES is Data Encryption Standard and, the abbreviation of AES is Advanced Encryption Standard. DES and AES are two examples of block ciphers that are symmetric, but with differences. To put it in simple terms, they are two different encryption standards.

The term DES is the short format of Data Encryption Standard. The words encryption standard is quite familiar among people as a lot of them have at least heard about it. People have a vague idea of these encryption standards. DES was created back in 1976 when computers were relatively new.

The term AES is the short format of Advanced Encryption Standard. The words encryption standard is quite familiar among people as a lot of them have at least heard about it. People have a vague idea of these encryption standards. AES was created in 1999, around the time computer was famous.

Comparison Table Between Des and Aes

Parameters of Comparison

Des

Aes

Abbreviation

DES is the acronym of Data Encryption Standard.

AES is the acronym of Advanced Encryption Standard.

Creation

It was created in the year 1976.

It was created in the year 1999.

Key length

The key length of DES is 56 bits.

The key length is 128 bits, 192 bits, and 256 bits.

Security

It is not so secure and can be broken easily.

It is much more secure.

Encryption

It can encrypt up to 64 bits of just plain text.

It can encrypt up to 128 bits of just plain text.

What is Des?

The term DES is used widely in the areas of encryption and technology. The word DES can be abbreviated into Data Encryption Standard. As the name suggests, it is a type of data encryption that was in use. This type of DES was created in the year 1976. It was when computers were just introduced. Also, access to a computer was limited to a few people. The DES is relatively older than others.

The term DES has gone quite out of use in the recent past. People are aware of the encryption standards. But they do not understand how exactly these standards work and the differences. As a person who is interested in tech, it is necessary to understand the fundamental differences that power the DES and the AES. The DES is much older, so the technicalities of that are low compared to our times.

The key length of the Data Encryption Standard is just 56 bits. It can encrypt up to 64 bits of plain text as the input. Under the DES, a block is encrypted with data in the size of 64 bits per block. It is also not so secure and can be broken without any struggle. DES is much slower than the new standards and, it was designed by the prominent tech corporation IBM.  

What is Aes?

The term AES is used widely in the areas of encryption and technology. AES can be abbreviated as Advanced Encryption Standard. As the name suggests, it is a type of data encryption. AES was created in the year 1999. It was when computers were popular around the world and were accessible to everyone. The AES is relatively newer than the DES.

The term AES continues to remain a vital part of the encryption standards done today. People are aware of the encryption standards. But they do not understand how exactly these standards work and the differences. As a person who is interested in tech, it is necessary to understand the fundamental differences that power the DES and the AES. The AES is much newer so, the technicalities of that are relatively better than the DES.

The key length of the Advanced Encryption Standard can be 128 bits, 192 bits, or 256 bits. It can encrypt up to128 bits of plain text as the input. Under the AES, a block is encrypted with data in the size of 128 bits per block. It is pretty secure and cannot be broken easily. AES is much faster than the previous standards. It was designed by Vincent Rijmen and Joan Daemen.

Main Differences Between Des and Aes

  1. The abbreviation of the word DES is Data Encryption Standard. The abbreviation of the word AES is Advanced Encryption Standard.
  2. The DES was created in the year 1976 when the computer was not available or accessible for everyone. The AES DES was created in 1999 when computers were famous and accessible.
  3. The security of this old DES system is poor and can be broken. The AES is far more secure and cannot be broken easily.
  4. The DES was designed by the prominent company IBM. The AES was designed by two people, Vincent Rijmen and Joan Daemen.
  5. The old DES is slow with the process. The AES is relatively faster with the process.

Conclusion

Some of the terms used in the areas of technology can be too technical for a layman to understand. In case a person tries to understand these terms, he or she ends up confused with different types of data encryptions or other terms. Hence, it is necessary to develop a clear understanding of the types of data encryptions and the differences between them.

The DES is an old system that is abbreviated into Data Encryption Standard. It was created by IBM in 1976 and is outdated in current times. The AES is the recent system that is abbreviated as Advanced Encryption Standard. It was created in 1999 and is relatively faster and more secure than others.
