What is a disposable pad?
A disposable pad is a type of encryption algorithm used in cryptography, where the key that encrypts and decrypts the message is used only once. Obviously, a disposable pad, sometimes shortened to OTP, is not the most effective use of resources. A disposable pad requires so much resources to create it as a key with multiple uses, but must be destroyed after one use. However, when the correct procedures are followed, OTP cannot be broken because each of them is different, so it is useful to create in certain situations.
In essence, cryptography is a process of hiding information and a one -time PAD is a tool used to hide data inside the code. When using cryptography, one person would encrypt a message that includes the use of OTP or other key type to the message. A person who receives a message would then use the key to decrypt and read the message. Many people consider cryptography only as a method that governments and military groups create codes of massive reports. Different types of cryptography are used to SCovering information in various formats, such as computer passwords and ATMs.
To be considered a perfect disposable pad, the key must contain exactly as much data as the text to be encrypted, also called a simple text. There may only be two copies of the keys, one for the sender and one for the receiver and both sides must destroy the key after decryption of the message. Finally, the key must be random. Some "random numbers" generators on computers actually monitor the pattern for generating numbers, giving only the appearance of random.
When using the right use, a disposable pad is considered perfectly safe, because someone who is trying to decipher the code could not rely on other codes or messages for tracks. The cryptanalyst is able to compare and compare several messages that use multi -use key, Applying Statistical analysis or patterns comparing, and finally the key solution. WITHHowever, the one -time key is the only traces in a single report, making it impossible to break the key to the cryptanalysis.
The term "pad" concerns the time when the code was printed on a pad of paper filled with random OTP codes. Once the code is used, the upper sheet of the pad would be destroyed and revealed another code for another disposable pad. Computers randomly generate today's OTP as they have for many years.
