Identify in the alternatives which encryption process the paragraph above refers to: 'The encryption process is to transform original information into another non-intelligible one in a process that can be reversed, that is, the information can return to its initial form as long as it is combined with its key. Without the key, decoding is not possible, which means access restriction, a very interesting feature for information security systems.'


a) Symmetric key encryption.
b) Asymmetric key encryption.
c) Cipher key encryption.
