453 | This is the Deflate algorithm (RFC1951), specified for use in | |
454 | IPSec with the IPCOMP protocol (RFC3173, RFC2394). | |

462 | Michael MIC is used for message integrity protection in TKIP | |
463 | (IEEE 802.11i). This algorithm is required for TKIP, but it | |
464 | should not be used for other purposes because of the weakness | |
465 | of the algorithm. | |
