Encryption

Encryption

1. Encryption is the process of disguising messages or data

   • It is 'scrambling' data

2. Encryption is done to ensure that only the intended recipient can understand the data

3. If unauthorised can gain access to encrypted data unlawfully, it will be meaningless to them

4. Encryption involves data being arithmetically transformed before transmission in a scrambled form

5. Encryption uses a RANDOM process set up using a special key value, the data is then decoded when recieved

6. Why is encryption used?

   • To provide security of data
     • Especially during transition over the internet when the data is liable for interception
   • So that unauthorised people can not access sensitive data for example credit card details
   • To ensure sensitive data can only be accessed by those for whom the data is intended
   • To protect important data that may be hacked or stolen
