What are two problems with the one-time pad?
The two problems are; 1. The One time pad needs to be truly random. Pseudo random generators are quick however they can be predicted. The second is practicability of being able to transmit the number of keys securely to the receiver. For every bit of plain text, there is also 1bit of key.
How would one describe pad printing?
Pad printing can be described as a process where two dimensional images are transferred on three dimensional objects. Pad printing is used on golf balls and keyboards.
What pseudo-random block stream is generated by 64-bit OFB with a weak DES key?
With (OFB) output feed back, a random 64-bit number, known as the IV is encrypted with the weak secret key to create the one-time pad. A weak DES secret key is one which is either all 1's, 0's or alternating ones and zeros. The plain text is XOred with as many bits of the generated one-time pad. If a weak key patterns will emerge in the ciphertext. - Eric Appelboom
What are some Everyday items that were used in the 1870's?
One item was a washing board that looked like a pad with lines in it
You have 28x20 square feet how many cubic yard concrete you do whants?
That depends on how deep you pour it.The number of cubic yards you need is(length of the pad in feet) x (width of the pad in feet) x (depth of the pad in inches)/324For your 28' x 20' pad, that's [ (1.728) x (depth in inches) ] cubic yards.
Do encryption export controls apply to implementations of the one-time pad?
There are no export controls per se on the one-time pad - however, there could easily be controls on elements of the implementation of the one-time pad. For example, if the one-time pad is sent using encryption that is subject to export controls, the implementation would be subject to export controls because of that.
What comes closest to being perfectly secure encryption scheme a- one-time pad b- caesar cipher c- DES d- RSA?
One Time pad
How many devices can you charge at one time on a battery charging pad ?
The pad can charge as many batteries as it is destined to charge. Most pads charge about 4 batteries at a time.
How often do you change your dining table pad?
There are several times when it may be time to change the dining table pad. One may have a big spill that ruins the pad or it may get burned by a very hot pan.
When the breaks are pressed on your car there is a rattling noise?
The only time my brakes rattled was when a retaining clip on the brake pad broke letting the pad rattle around. I pulled the tire and wheel off, replaced the one retaining clip on the one pad and replaced the wheel and tire.
Can you use one adult pad and one child pad for an adult?
The answer is no. The way the Automated External Defibrillators (AED) are set up today you can only plug in one set of pads into the machine at a time; either the children pads or the adult pads.
Is lily pad one word?
it is two words, lily pad
How do you put in alt codes?
You first need to have a number pad on your CPU... (alot of laptops do NOT) then you hold down alt the whole time and on the number pad you type in one number at a time... for me the number 4 and 7 do not work HOPE THAT HELPS :D
How do you know when your pad is full?
Whenever your pad feels heavy. Check it every time you go to the restroom.
Can you use one adult and one child aed pad?
No you can not use one adult and one child aed pad.
Where can one purchase a hearth pad?
One can purchase a hearth pad from stores like Kidkusion or Argos. The hearth pad available at the former sells for $96. The one available at the latter sells for $45.
What one time pad does if used correctly?
If used properly, the one-time pad is an unbreakable encryption system. To implement it, two parties agree on an invertible transformation on messages and a random key (such as a random number or sequence of numbers). The random key is then used to encrypt and decrypt the message, and if it is only used once, will leave no meaningful pattern in the ciphertext. Thus malicious third parties that intercept the ciphertext will be unable to derive the original message from it. The random key is the one-time pad because it can be used only once.
