Without encryption, our lives would be much different and unsecure. According to Oded Goldreich (2004), There are 2 main types of encryption: One is called Symmetric-key and the other is public-key encryption (pp 375-376). The Symmetric-key algorithm uses the same cipher for both encryption and decryption. Conversely, the public-key algorithm requires 2 separate keys. One of these keys encrypts the text or…show more content…

It doesn’t seem to be slowing down at all. Encryption is a great tool that is protection the assets of many companies.
