Blowfish a new secret key block cipher having maximum speed and included in a large number of cipher suites and encryption. It is a Feistel network, iterating a simple encryption function 16 times. The block size is 64 bits, and the key can be any length up to 448 bits. Blowfish requires a complex initialization process before starting the actual encryption, how ever this is considered to be a very efficient mechanism for encryption on large microprocessors.
For a complete seminar on The Blowfish Encryption Algorithm , research on following points:
- Cryptanalysis of Blowfish
- Encryption algorithms
- Block cipher: 64-bit block
- Variable key length: 32 bits to 448 bits
- Much faster than DES and IDEA
- Unpatented and royalty-free
- Designed by Bruce Schneier
- Key length
- Cipher
- MacGuffin
- Threefish
- Embedded systems
