Add TEA, and link to 3DES

| Jun 5, 2013 at 8:27 | comment | added | fgrieu♦ | @user7060: 64-bit block ciphers are deprecated for new applications, but still very much in use in some fields, including mine (Smart Cards). French recommendations recommend 128-bit block ciphers, but allow 64-bit block ciphers (for introduction) till 2020, provided they are used within rules. | |
| Jun 5, 2013 at 7:52 | comment | added | Dingo13 | I thought that all 64-bit block cipher were deprecated. This is interesting.Thank you very much. | |

The stated bound on $n$ is safe for more $k$ than originally stated.
