Encryption Methods

AES: The Advanced Encryption Standard (AES) is a computer security standard and its cryptography scheme is a symmetric block cipher that encrypts and decrypts 128-bit blocks of data. Lengths of 128, 192, and 256 bits are standard key lengths used by AES. The algorithm consists of four stages that make up a round which is iterated 10 times for a 128-bit length key, 12 times for a 192-bit key, and 14 times for a 256-bit key.

The first stage ("SubBytes" transformation) is a non-linear byte substitution for each byte of the block. The second stage ("ShiftRows" transformation) cyclically shifts (permutes) the bytes within the block.

The third stage ("MixColumns" transformation) groups 4-bytes together forming 4-term polynomials and multiplies the polynomials with a fixed polynomial mod (x^4+1). The fourth stage ("AddRoundKey" transformation) adds the round key with the block of data.

AES does not have a Feistel structure but is composed of three distinct invertible transforms based on the Wide Trial Strategy design method.

The Wide Trial Strategy design method provides resistance against linear and differential cryptanalysis. In the Wide Trail Strategy, every layer has its own function:

The linear mixing layer: guarantees high diffusion over multiply rounds.

The non-linear layer: parallel application of S-boxes that have the optimum worst-case non-linearity properties.

The key addition layer: a simple XOR of the round key to the intermediate state.

Blowfish: Some of the features of Blowfish are:

Offers 64-bit cipher block.

32 bits to 448 bits variable key lengths

Much faster than DES and IDEA.

No license required.

Freely Available.

Designed as a fast, free alternative to existing encryption algorithms.

Offers high level of security, and the keys cannot be broken.

GAMMA: This is a more secure encryption method that allows 32 bits key length and provides much more security than AES and BlowFish.

GHOST: This is a more secure encryption method that allows 32 bits key length and provides much more security than AES and BlowFish.
