A Bitsum Attack research based on TEA
Jiayin Tian, Xu Kuo Gao · 2016
With the increasing number of applications for security in small devices and short lived transactions services, and the encryption algorithm which we need is faster, more convenient, and more secure. TEA is one of them. In this paper, there are four experiments with 64 and 128 bit size key TEA. The results of the experiments proving that TEA cannot defend Bitsum Attack. The reason is in TEA the bitsum of the key and the ciphertext have strong relation.
