The most common encryption algorithms are collected in the following table − Encryption Algorithm Stream Cipher − It converts plaintext into cyphertext in a bit-by-bit fashion.īlock Cipher − It operates on the fixed-size blocks of data. To start speaking about wireless encryption, it is worth saying that there are 2 types of encryption algorithms: Stream Cipher and Block Cipher. Is that risk big enough, to stop using algorithm 'X' for encryption? I doubt it, the information to be protected might be outdated at that point of time. All the algorithms that we use every day may be broken, but what is its likelihood of this happening with current technology and time?įor example, it might take around eight years to break encryption 'X' using new super-fast computers. To be honest with you guys - there is no fully secure encryption scheme. And, to protect the information efficiently, it must be encrypted in a way that would not allow an attacker to decrypt it. Some information is too valuable, not to be protected. Every time you access your web bank or mailbox, most often when you log in to any type of web page, or create a VPN tunnel back to your corporate network. Nowadays, we use encryption every single day, without even noticing. In general, encryption is the process of transforming the data, into some kind of cyphertext that would be non-understandable for any 3 rd party that would intercept the information.
