PRESENT is a block cipher
with 31 rounds and its several variants need 2520 to 3010 GEs to provide good enough security levels.
The Rijndael algorithm is a symmetric block cipher
that supports key sizes of 128, 192 and 256 bits, with data handled in variable-length blocks.
One easy way how to overcome this problem is to use a symmetric Block cipher
with some modifications.
They defined the problem and proposed an encryption method based on an existing block cipher
(DES) in Cipher-FeedbackMode (CFB), which a series of data and key dependent offsets that can be used to encrypt each character of a formatted string by adding the offset.
the proposed ECBFSC is a simple block cipher
with block size of 8-bit and 256-bit secret key.
A symmetric key block cipher
algorithm, such as the Data Encryption Standard (DES) specified in Federal Information Processing Standard (FIPS) 46-3 and the proposed Advanced Encryption Standard (AES), are implemented in various modes, depending on specific applications.
Representative symmetric key encryptions are: the Advanced Encryption Standard (AES), the 64-bit block cipher
"MISTY" developed by Mitsubishi Electric and the 128-bit block cipher
"Camellia" which was jointly developed by NTT and Mitsubishi Electric in 2000.
