Question

For encryption, what does it mean for data to be in transition and in use? What are the major security concerns with data encryption?

Answer 1

Data transition mean is data can be changed during the communication.for example If two people communicate with each other their data can be transfered in the network.hackers always try to capture the information.so if the data can be passed normal way hackers able to read the data.this is not good thing.for example two frnds want share secrets among the people.they used some coding language.only they know how to concert what they say.but rest of people don't know.what they are talking.same thing exists in real life encryption.during the communication over the network we used the encrypted data for the secure communication.

The major security concerns with encryption.we must use strong encryption algorithms which are highly not hackable.for example take sample data hello it can encrypt to aghio as encryption now the receiver will receive the data aghio they can't understand what it mean.so we must decrypt The data as hello from aghio.the logic is simple the sender will sent the data in encryption form and the receiver will receive the decrypted data.we must not use same key as encryption and decryption.if we use same key attacker will simply know the key and decrypted the data so there will be no security
