8. Conclusion
DEAL(Data Encryption Algorithm with Large Blocks)
DEAL has a 128-bit block size and allows for key sizes of 128, 192 and 256 bits
Basic structure: a Feistel Cipher using DES as round function
Can be implemented using existing DES-hardware and DES-software
As fast as triple-DES, no obvious weak keys and the complimentation property
No known, feasible attacks
