hello,
I am doing Tiny Encryption Algorithm (TEA) research work using VHDL language. I have to come up with a 1 bit and 8 bit full Adder(FA) & subtractor and 8 bit XOR. I have to encrypt and decrypt them and use shift left 2 times, and shift right 3 times. Block sizes are 16 bits, Key sizes are 32 bits and cycles 8 bits. Delta is given by root 5 - 1 multiply by 2 to the power of seven.
I cant get started as i don't understand the thing at first. Have considerable knowlegde of VHDL but this thing, i got no idea about.
Can anyone please explain to me whats this all about.
Thanks
