cryptanalysis: TEA suffers from equivalent keys and can be broken using a related-key attack requiring 223 chosen plaintexts and a time complexity of 232. The best structural cryptanalysis of TEA in the standard single secret key setting is the zero-correlation cryptanalysis breaking 21 rounds in 2121.5 time with less than the full code book
