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replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated.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.

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.

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replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated.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.

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. Furthermore, different actions by the same person cannot be linked. Certificate holders have control over what information is disclosed, and to whom.

Subsets of the proposed cryptographic building blocks can be used in combination, allowing a cookbook approach to the design of public key infrastructures. Potential applications include electronic cash, electronic postage, digital rights management, pseudonyms for online chat rooms, health care information storage, electronic voting, and even electronic gambling.

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. Proposed blockchain-based PKI designs are built as public ledgers linking identity with public key, providing no privacy.

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? That it doesn't solve the problems that it claims? Or that it is too expensive?

Беккер увидел в ее руке сережку в виде черепа. - Так это клипса. - Да, - сказала девушка.  - Я до чертиков боюсь прокалывать уши.

Он лежал, устремив глаза к небу и продолжая прижимать руку к груди. Внезапно камера отъехала в сторону, под деревья. В кадре возник мужчина в очках в тонкой металлической оправе, в руке он держал большой портфель. Выйдя на открытое место и бросив взгляд на корчащегося на земле Танкадо, он задвигал пальцами, словно исполнял ими какой-то причудливый танец над коробочкой, которую держал в руке.

 Производственный. Анализ затрат на единицу продукции.  - Мидж торопливо пересказала все, что они обнаружили с Бринкерхоффом.

На это уходило много времени, но математически гарантировало успех. Когда мир осознал возможности шифровки с помощью грубой силы, пароли стали все длиннее и длиннее. Компьютерное время, необходимое для их угадывания, растягивалось на месяцы и в конце концов - на годы. К началу 1990-х годов ключи имели уже более пятидесяти знаков, в них начали использовать весь алфавит АСКИ - Американского национального стандартного кода для обмена информацией, состоящего из букв, цифр и символов. Число возможных комбинаций приблизилось к 10 в 120-й степени - то есть к единице со 120 нулями.

Родители… Сьюзан. О Боже… Сьюзан. Впервые с детских лет Беккер начал молиться. Он молился не об избавлении от смерти - в чудеса он не верил; он молился о том, чтобы женщина, от которой был так далеко, нашла в себе силы, чтобы ни на мгновение не усомнилась в его любви.

Звуки шифровалки впервые за всю историю этого здания ворвались в помещение Третьего узла. Сьюзан открыла. Сквозь отверстие в двери она увидела стол. Он все еще катился по инерции и вскоре исчез в темноте. Сьюзан нашла свои валявшиеся на ковре итальянские туфли, на мгновение оглянулась, увидела все еще корчившегося на полу Грега Хейла и бросилась бежать по усеянному стеклянным крошевом полу шифровалки. ГЛАВА 68 - Ну видишь, это совсем не трудно, - презрительно сказала Мидж, когда Бринкерхофф с видом побитой собаки протянул ей ключ от кабинета Фонтейна.
