Abstract
Tiny Encryption Algorithm (TEA) is one of the fastest Encryption Algorithms. It is a lightweight cryptographic algorithm with minimal source code. Due to its simple logic in key scheduling TEA has suffered from related key and equivalent key attacks. Therefore a modified key schedule is proposed for TEA. The new key schedule applies Boolean function based SBox to generate different round keys for TEA. The resultant Modified TEA achieves better security than original TEA. The execution time analysis of modified TEA is also presented.
