Multiple Objectives of Lawful-Surveillance Protocols
Résumé
In recent work on open, privacy-preserving, accountable surveillance, we have proposed the use of cryptographic protocols that enable law-enforcement and intelligence agencies to obtain actionable information about targeted users of mass-communication systems without intruding on the privacy of untargeted users. Our suggestion that appropriate technology, combined with sound policy and the rule of law, can afford typical users significantly more privacy than they have now without hindering lawful and effective actions by law-enforcement and intelligence agencies has met with considerable skepticism. In this paper, we summarize the principal objections to our approach and address them.

Communications Assistance for Law Enforcement Act
The Communications Assistance for Law Enforcement Act (CALEA), also known as the "Digital Telephony Act," is a United States wiretapping law passed in 1994, during the presidency of Bill Clinton (Pub. L. No. 103-414, 108 Stat. 4279, codified at 47 USC 1001-1010). CALEA's purpose is to enhance the ability of law enforcement agencies to conduct lawful interception of communication by requiring that telecommunications carriers and manufacturers of telecommunications equipment modify and design their equipment, facilities, and services to ensure that they have built-in capabilities for targeted surveillance, allowing federal agencies to selectively wiretap any telephone traffic; it has since been extended to cover broadband Internet and VoIP traffic.
Protocole cryptographique
Un protocole de sécurité (protocole cryptographique ou protocole de chiffrement) est un protocole abstrait ou concret qui remplit une fonction liée à la sécurité et applique des méthodes cryptographiques, souvent sous forme de séquences de primitives cryptographiques. Un protocole décrit comment les algorithmes doivent être utilisés et inclut des détails sur les structures de données et les représentations, à quel point il peut être utilisé pour implémenter plusieurs versions interopérables d'un programme.
Lawful interception
Lawful interception (LI) refers to the facilities in telecommunications and telephone networks that allow law enforcement agencies with court orders or other legal authorization to selectively wiretap individual subscribers. Most countries require licensed telecommunications operators to provide their networks with Legal Interception gateways and nodes for the interception of communications. The interfaces of these gateways have been standardized by telecommunication standardization organizations.
