What is the key of the session?
The key of the session is a temporary method of encryption information. When the user opens the communication session, the key for a particular session is generated. This key is used for all communication during this period and after the session is over, it is discarded. Session keys are usually symmetrical and relatively simple in terms of cryptography. This simplicity would generally be the main disadvantage of using the key, but because so many keys are in operation at the same time and the keys are not used too long, it is not a problem.
cryptography works using keys. One key is used to scratch or encrypt data and the other is used to upset or decrypt. When these keys are the same or at least very similar, then they are symmetrical. If the keys are very different, it is an asymmetric system. In most cases, the symmetrical key is less safe than asymmetric, because the interruption of one key completely opens the code.
The session of the session varies from typical keys in one main way; Are created so that aby existed for a very short time. Unlike the normal key that can be used without changes for years, the session key should only be used for several seconds to several hours. For example, a key is generated when a user connects to checking his e -mail and then discarding when he logs off. This gives these keys a number of advantages and disadvantages that are unique to this encryption style.
Their main advantage is their volume. Since each communication session uses a unique key, even the average company can generate hundreds of keys every day. The mere number of keys that a potential attacker would have to sieve only to access important information is huge. While any given session key can be relatively easy to break, the likelihood that this random key with important information is very low.
One of the main influences on the ease of breaking the key is the amount of encrypted material that can be used for information. The more material is availableI, the easier it is to break. Because the key of the session has a very small amount of reference material, the simplicity of the key is less important.
On the other hand, the sitting keys are known for poorly made algorithms and easily broken codes. This is particularly evident when attackers actually start looking for patterns in key generation or reverse engineer a real algorithm. In one of these cases, the key session system breaks wide and does not provide any security at all.
