Today, a group of 83 prominent Internet inventors and engineers sent an open letter to members of the United States Congress, stating their opposition to the SOPA and PIPA Internet blacklist bills that are under consideration in the House and Senate respectively. Dr. Steven Bellovin, AT&T Research Luis Sanchez, BBN Technologies Abstract: Late last year, the IPsec working group of the Internet Engineering Task Force (IETF) published the long awaited Ipsec standards, as RFCs 2401-2410. More precisely, who should be responsible for coping with computer insecurity - governments or the private sector? Whenever someone says that something is encrypted, the first question you should ask is, "What about the keys?" For years, legal wiretapping was straightforward: the officer doing the intercept connected a tape recorder or the like to a single pair of wires. Term from queries and indexes could be stemmed by then a lookup table. Recently, obligations are increasingly being expressed as part of security policies. Steven M. Bellovin is a researcher on computer networking and security. Many security problems can be traced to improper implementations.
