Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. As paper-based communication and transaction mechanisms are replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated. Most security experts believe that digital certificates offer the best technology for safeguarding electronic communications.

Abstract: Public Key Infrastructure PKI has now passed its first decade of activity on the Internet, but has yet to break out of pathetically small revenues. Reasons and factors contributing to the failure are many and varied. Is it that the PKI is a solution looking for a problem?

Rethinking Public Key Infrastructures and Digital Certificates

Digital signature technology, based on public key cryptography, has been claimed as the appropriate means of achieving this aim. Digital signatures do little, however, unless a substantial 'public key infrastructure' PKI is in place to provide a basis for believing that the signature means something of significance to the relying party. This paper examines that form of PKI architecture, and concludes that the reason for its failure is its very poor fit to the real needs of cyberspace participants. Its key deficiencies are its inherently hierarchical and authoritarian nature, its unreasonable presumptions about the security of private keys, a range of other technical and implementation defects, confusions about what it is that a certificate actually provides assurance about, and its inherent privacy-invasiveness. Alternatives to conventional PKI are identified. Contents 1.

Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. As paper-based communication and transaction mechanisms are replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated. Most security experts believe that digital certificates offer the best technology for safeguarding electronic communications. They are already widely used for authenticating and encrypting email and software, and eventually will be built into any device or piece of software that must be able to communicate securely. There is a serious problem, however, with this unavoidable trend: unless drastic measures are taken, everyone will be forced to communicate via what will be the most pervasive electronic surveillance tool ever built.

As paper-based communication and transaction mechanisms are replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated. Most security experts believe that digital certificates offer the best technology for safeguarding electronic communications. They are already widely used for authenticating and encrypting email and software, and eventually will be built into any device or piece of software that must be able to communicate securely. There is a serious problem, however, with this unavoidable trend: unless drastic measures are taken, everyone will be forced to communicate via what will be the most pervasive electronic surveillance tool ever built. There will also be abundant opportunity for misuse of digital certificates by hackers, unscrupulous employees, government agencies, financial institutions, insurance companies, and so on. In this book Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. Such certificates function in much the same way as cinema tickets or subway tokens: anyone can establish their validity and the data they specify, but no more than that.

DOI: Conventional public-key infrastructure PKI designs using certificate authorities and web-of-trust are not optimal and have security flaws. The properties afforded by the Bitcoin blockchain are a natural solution to some of the problems with PKI - in particular, certificate transparency and elimination of single points-offailure.

После каждой из них следовал один и тот же ответ: ИЗВИНИТЕ. ОТКЛЮЧЕНИЕ НЕВОЗМОЖНО Сьюзан охватил озноб. Отключение невозможно. Но. Увы, она уже знала ответ. Так вот какова месть Танкадо. Уничтожение ТРАНСТЕКСТА.

 Да? - Меган внезапно насторожилась. Беккер достал из кармана бумажник. - Конечно, я буду счастлив тебе заплатить.

Если нет, он войдет и будет двигаться на восток, держа в поле зрения правый угол, единственное место, где мог находиться Беккер. Он улыбнулся. ОБЪЕКТ: ДЭВИД БЕККЕР - ЛИКВИДИРОВАН Пора. Халохот проверил оружие, решительно направился вперед и осмотрел площадку.

Поднял посверкивающую полуавтоматическую беретту и нацелил ее на дверь, а потом опустил себе на колени. - Сьюзан, - сказал он торжественно.  - Здесь мы в безопасности. Нам нужно поговорить.

Я не могу этого сделать.  - Скрестив на груди руки, он вышел из ее кабинета. Мидж горящими глазами смотрела ему вслед.

 - Мою колонку перепечатывают в Соединенных Штатах, у меня отличный английский. - Мне говорили, - улыбнулся Беккер. Он присел на край койки.  - Теперь, мистер Клушар, позвольте спросить, почему такой человек, как вы, оказался в таком месте. В Севилье есть больницы получше.

На плюшевом диване, закутавшись в махровый халат, грелся на солнце Дэвид и внимательно за ней наблюдал. Она протянула руку, поманив его к. - Без воска? - тихо спросила она, обнимая. - Без воска.  - Он улыбнулся в ответ.
