I can only guess that you ask about the performance of the DES algorithm when implemented in software as opposed to hardware. Any algorithm that can be economically implemented in hardware will perform faster in hardware than software by orders of magnitude in the general case. Encryption algorithms such as DES are often based on a shift-combine-shift sequence, which is fairly easy to implement in hardware, but can take considerable processing time when implemented in software.

Comapre between double DES and Triple DES?
double DES is less secure than triple DES triple DES is much slower than double DES double DES is within the range of brute force attack. but triple DES is not in the range of brute force attack.
Why did the computer get slower after the antivirus?
Anti-virus software are programs that run on your computer. At any one time there are lots of programs running on your computer. The more that are running, the slower the computer can work. So when you install a new program like anti-virus software, it is an extra program to run which will make your computer slower. It is still important that you do use anti-virus software, even if it does slow down your computer.
What are problems commonly experienced with Cpm Software?
CPM software has received great reviews. The only problem you may have is your systme may run a little slower.
What are implications of computer software on computer hardware?
makes the computer and the hardware within faster or slower, also if its a big software file it can give you less hard drive space.
How do you know if your computer has a virius?
If your computer is slower than usual or behaving oddly, you may have a virus. Install a virus scanner and scan your computer.
Why is your Sony Vaio VGN-NR120E notebook responding slower?
Can you give more specifications about the "responding slower" issue, and give some detais about your Sony Vaio hardware and software? Because there are qutie too many causes.
Why do the computers get slower when they get older even when you format them?
It's not about computers, it's about software which requires more and more computer resources with each release.
The problem of software that are larger than necessary?
It is called software bloat where larger programs become perceptibly slower,use more memory,disc space or processing power.
What has the author Knut Koslowski written?
Knut Koslowski has written: 'Unterstutzung von partizipativer Systementwicklung durch Methoden des Software Engineering'
Why does Windows slowdown after installing more software?
It might not necessarily be that Windows itself is slowing down. A more likely cause is that the computer which now has more software on its hardware, takes a longer time to process everything, making Windows seem slower.
Disadvantage of ipod touch 3g 8gb?
You have to carry around a phone, and an itouch.You run out of space quickly and the software is slower than a 3g 32gb or 64gb or the 4g.
If you have 2 computers connected to the same router then why is the second computers download speed slower?
It's difficult to say from here without more information, but the things I'd look at are:Are the two machines the same - does the slower machine have less memory, slower hard drive, slower processor or different software? Are the files being transferred to the main drive of the computer - for example, FAT is much slower than NTFS so if download to a FAT formatted memory stick, it will be a lot slower. Are both PCs connected in the same way? (if one is wireless connected and the other using a cable, the wireless will be a lot slower).Are there any errors being reported for the Ethernet connection on the PC?
