Abstract

Consumer computing devices are insecure by design, and, to use the words of Web founder Tim Berners-Lee (TBL), the Internet has been subverted into the 'world's largest surveillance network'. TBL and other Internet pioneers, such as Brewster Kahle (famous for the Internet Archive) and Vint Cerf (famous for TCP/IP), are promoting the 're-decentralisation of the Web', in order to deny both governments and dominant corporations the population control that they crave. The Internet Architecture Board (IAB) and Internet Engineering Task Force (IETF) have raised expectations about security within Internet protocols (e.g. through RFCs 6973 and 7624).

At the consumer level, computer scientists produce Privacy Enhancing Technologies (PETs), but the use of PETs is very limited, even by the people who need them most. So a yawning gap exists between the need and the reality. In order to bridge this chasm, IT facilities must be re-conceived, with security and privacy inherent in devices, software, protocols and interfaces. What are the key characteristics of an IT ecology that is secure (as well as effective, efficient and adaptable), and what has to be done to overcome the barriers to such an ecology emerging?


Contents


[NOTE: For each section in the body of the paper,
a systematic review of the PETS literature needs to be undertaken.]

1. Introduction

Electronic devices and networks have conrtibuted greatly to people's effectiveness and efficiency, but they have brought with them many security vulnerabilities. The purpose of this Workshop is to make progress in overcoming the gap between the large menagerie of privacy-enhancing technologies (PETs) on the one hand, and, on the other, the unfulfilled need for products and services that embody security and privacy protections. Specifically, the intention is to articulate the needs, and delineate measures needed to move from a scatter of very partial tools to one or more secure tool-sets that people actually install and use.

The format of the Workshop comprises:

The next section outlines the contemporary, insecure context. That is followed by consideration of the various aspects of the need for Secure eWorking Environments. The array of existing tools is surveyed, and deficiencies noted. This leads to suggestions for generic requirements and architectural principles. The final section discusses how comprehensive and integrated working environments can come into being.


2. The Context

We live in a world of insecure devices (Clarke & Maurushat 2007, Clarke 2011, Clarke 2013, Quinn 2014), and insecure networks (Hardy 2016). This has arisen from and been exacerbated by productisation processes that primarily serve the interests of corporations not individuals. Current examples include the replacement of general-purpose computing by limited 'appliances' whose use is controlled by the supplier, the replacement of local storage and processing by 'cloud-based' services, and the conception of 'the Internet of Things' as tools not to serve individuals but to monitor them.

Individuals are subject to threate from government agencies, from corporations and from other individuals. Parliaments grant government agencies warrantless access to data and exemptions against 'computer crimes' legislation. Once-ephemeral communications that are now processed in digital form are subjected to 'data retention' requirements. Corporations impose onerous conditions on consumers, acquire vast amounts of personal data, exploit it, and traffic in it. Individuals are subjected to location-detection, tracking, stalking, pursuit, interdiction, inference of intentions on the basis of location, and inference of associations on the basis of co-location (Clarke & Wigan 2011, Michael & Clarke 2013).

Despite attempts to achieve international harmonisation (e.g. CoE 2001), jurisdictions vary considerably in the particular forms of intrusiveness that government agencies are authorised to impose. Carrying devices across borders creates particular challenges EFF (2014).


3. The Needs

This section considers the elements of a desirable state of protection for individuals against the context of insecurity noted above.

3.1 Generic Functional Requirements

Among security professionals, a longstanding checklist of attributes of a (relatively) secure state is Confidentiality, Integrity and Availability (CIA). This list is subject to many criticisms. The following set of security features is suggested as being that necessary to provide safety for individuals, and for their family, associates and informants (after Clarke 2016b):

Another approach that can be taken is to identify features that represent the absolute minimum set of safeguards that a person or organisation needs to take. One example is EFF's 'security starter pack' (EFF 2014). Another is the 'baseline security' defined in Table 1 and Appendix 2 of Clarke (2015), complemented by lists of additional security features in Appendices 3 and 4.

In order to satisfy these generic needs, it is likely to be necessary to obfuscate and to falsify. The term 'obfuscation' encompasses means for hiding, obscuring, making vague, or aggregating with others of a similar kind into a composite; whereas 'falsification' covers various forms of active misrepesentation in order to avoid, deter or even prevent exposure to an adversary, or to mitigate the harm arising from an attack. Sometimes it is data or messages that need to be hidden or obscured. In other circumstances, the risks may involve exposure of the person's identity, or their location, or their social network (Clarke 2016a).

3.2 'Non-Functional' Requirements

In the terms used in the computing science literature, 'functional requirements' are those that deliver particular services to a system's users. Effective systems have other characteristics as well, however, and the highly inelegant term 'non-functional requirements' is conventionally applied.

Building on Clarke (2014b), the following characteristics are suggested as being critical to the adoption of Secure eWorking Environments:

3.3 Diversity

Anaysis of generic needs alone falls short of what is needed, because people's circumstances vary a great deal. One dimension of diversity is the source of threats, which may include one or more government agencies, corporations, and categories of individuals, such as criminal and business associates, political opponents, ex-friends, and estranged family-members. Another dimension is the resources and technical capabilities available to a person's adversaries.

It is also important to consider the nature of the individual's activities that are likely to be of interest to adversaries, and hence subject to attack. Distinctions that can be usefully drawn include:

It would be impossibly resource-intensive to consider the specific circumstances of each individual. A conventional approach to such problems is to conduct user segmentation. Relevant user segments include whistleblowers, human rights advocates in countries with unfriendly regimes, victims of domestic violence, protected witnesses, undercover operatives, and corporate executives working on mergers and acquisitions (GFW 2011, Clarke 2014a) .

3.4 Risk Assessment and Management Processes

Understanding is necessary of the needs of particular user segments. An appropriate and well-established technique exists to do this, variously referred to as (Threat) Risk Assessment (TRA or RA), which lays the foundation for Risk Management. This applies the language of the conventional security model in order to structure a readily-explained process, of the kind presented in Table 1.

Table 1: The Risk Assessment and Risk Management Process

From Clarke (2016b). See also EFF (2014)

Analyse

(1) Define the Objectives and Constraints

(2) Identify the relevant Stakeholders, Assets, Values and categories of Harm

(3) Analyse Threats and Vulnerabilities

(4) Identify existing Safeguards

(5) Identify and Prioritise the Residual Risks

Design

(1) Identify alternative Backup and Recovery Designs

(2) Evaluate the alternatives against the Objectives and Constraints

(3) Select a Design (or adapt / refine the alternatives to achieve an acceptable Design)

Do

(1) Plan the implementation

(2) Implement

(3) Review the implementation

The paper from which the table is sourced applies the technique to the practice of backup and recovery. An indicative risk assessment for a whistleblower is provided in Clarke (2014a).


4. Existing Tools

The insight that computer users are at risk is anything but new. Particularly since the mid-1990s, considerable activity has occurred within the discpline and profession of computer science aimed at mitigating those risks. Table 2 provides a catalogue of relevant tools (drawing on EPIC, EFF, PRISM-Break, Clarke 2014a, and other sources).

Table 2: Categories of PETs

Given that many exist, the question arises as to why users haven't adopted them to a far greater extent than they have done. A considerable number of impediments to the adoption of PETs are discussed in (Clarke 2014a). Key aspects are:


5. Architecture for Secure eWorking Environments

The previous sections have been concerned with the functionality that needs to be delivered, and the means whereby users can invoke that functionality. In order for Secure eWorking Environments to come about, however, it is necessary for collaborative development to be facilitated. This section considers architectural features that can underpin the emergence of satisfactory offerings and discusses possible test-applications.

5.1 Architectural Features

Architecture refers to the manner in which elements inter-relate. An effective architecture establishes a framework within which existing tools can be applied, and new tools can be envisaged, developed and integrated.

The following are suggested as key features of such an architecture (Clarke 1990, 2014):

5.2 Test Applications

In order to perform even a simplistic evaluation of the ideas being proposed, a test needs to be devised which is small enough to be workable, but complex enough to provide insights into the process and its practicability.

One useful test is to recognise the web-browser as being an important element in every eWorking Environment, because it supports not only display of content, and search for content, but also communications and transactions. To what extent is consumer-friendly browser-choice and -configuration feasible? An outline for such a project is in Clarke (2013). Mainstream browsers such as IE, Firefox and Chrome are highly insecure and/or privacy-invasive, but alternatives exist, and can be evaluated and/or enhanced to address the needs identified above.

Another test is to consider whether social media services can be implemented in a consumer-friendly manner. (Clarke 2014c) examined that question, identified key features that appropriate services need to contain, and evaluated the prospects of such services emerging.


6. Implementation Considerations

This section is concerned with how Secure eWorking Environments can come into being. This is a question of economic incentives and political processes.

6.1 Supply-Side

Alternative business models were considered in Clarke (2014c), and alternative approaches to addressing market failure were identified in Clarke (2015).

It is possible that enough businesses may perceive the scope for profit or enhanced market share through the development of such products. There has been only limited success in this area to date, but increased awareness of the need among consumers and citizens may herald a change.

6.2 Demand Side

Given suitable products, what needs to be done to attract individuals in the relevant target-markets to adopt them?

The following elements of strategy are suggested:


7. Conclusions

'Are we there yet?'. Clearly we are not. This Workshop involves consideration of the reasons why PETs remain merely promising and have not delivered sufficient value, and what can be done to generate momentum towards Secure eWorking Environments that have more comprehensive functionality, are internally cohesive, integrate adequately with users' devices and software, and are understandable and usable.

Resources on PET Adoption, Impediments and Architecture

Those references are listed below, in order of date of publication, that were identified using Google Scholar searches on:
<PETs privacy {architecture, integrated, comprehensive, requirements, specifications, productisation/z, market segments, threat models, whistleblower, domestic violence, undercover operative, protected witness, design, innovation, adoption, impediments}>
The searches were conducted on 30 Jul 2016, and were in most cases limited to the first 100 hits.

(For resources on PET usability factors, see http://www.rogerclarke.com/DV/UPETs-1405.html#PU).

Further searches were performed in the corpus of PETWorkshops and PETSymposia 2006-2014 and 2015-16. This found 3 more papers, bringing the total in that venue to a startlingly small 5. A possible reason for this can be found in the current Call for Papers for the 17th event in 2017, which presumably reflects Calls across the last two decades. This includes "Building and deploying privacy-enhancing systems" and "Human factors, usability and user-centered design for PETs", and in the text, "design, analysis, experimentation, or fielding of privacy-enhancing technologies". But the notion of architecture for PETs is nowhere to be seen. And neither are innovation (as distinct from invention), articulation, integration with other PETs, integration with systems software and applications software, relevance to people, feedforward into practice, adoption, impediments to adoption, and measures to overcome impediments to adoption.
