In part one, Osborne Clarke provides a legal opinion on the legal validity of electronic signature in the European Union. Part two has been prepared by OneSpan, and summarizes best practices recommendations for legal compliance when implementing e-signatures. eIDAS & E-SIGNATURE: A LEGAL PERSPECTIVE FOLLOW US 2 PART 1 Introduction The 2014 Regulation on Electronic Identification and Trust Services for Electronic Transaction in the Internal Market1 (“eIDAS”) went into effect throughout the European Union (“EU”) on 1 July 2016, replacing the 1999 Directive on electronic signatures2 (“the Directive”). Although the Directive had not been the subject of any disputes in its 16-year history, neither had it been a success. Its objective, to enable the widespread use of electronic signatures to conduct business across borders within the EU, was not met. There Are Three Key Reasons for This: I. Most EU Member States’ laws do not specify any form of signature for commercial contracts other than guarantees or contracts assigning real property. II. Many people mistakenly believed that the Directive mandated the use of advanced electronic signatures supported by a qualified certificate3 in order for an electronic signature to be legally effective.

Electronic signatures provide real benefits. For example, they promote the emergence of fully automated purchasing processes by enabling buyers and sellers to sign and approve transactions without the need for traditional “wet” (paper-based) signatures. 2 Johannes Döring: XAdES vs PAdES © 2017, INBATEK CO.,LTD, Thailand Legal overview Directive in force in every EU Member State about electronic signature: “data in electronic form which are attached to or logically associated with other electronic data and which serve as a method of authentication” Being deliberately neutral regarding technology and security requirements confers to all kinds of electronic signatures a potential legal validity provided their authenticity is not contested.

  • Enhancing the Reliability of Digital Signatures As Non-Repudiation Evidence Under a Holistic Threat Model
    UNIVERSITY CARLOS III OF MADRID DOCTORAL THESIS Enhancing the reliability of digital signatures as non-repudiation evidence under a holistic threat model Author: Jorge L´opez Hern´andez-Ardieta Supervisor: Prof. Dr. Ana Isabel Gonz´alez-Tablas Ferreres COMPUTER SCIENCE AND ENGINEERING DEPARTMENT Legan´es,February 2011 TESIS DOCTORAL Enhancing the reliability of digital signatures as non-repudiation evidence under a holistic threat model Autor: Jorge L´opez Hern´andez-Ardieta Directora: Prof. Dra. Ana Isabel Gonz´alez-Tablas Ferreres Firma del Tribunal Calificador: Firma Presidente: Vocal: Vocal: Vocal: Secretario: Calificaci´on: Legan´es, de de ii Abstract Traditional sensitive operations, like banking transactions, purchase pro- cesses, contract agreements etc. need to tie down the involved parties respecting the commitments made, avoiding a further repudiation of the responsibilities taken. Depending on the context, the commitment is made in one way or another, being handwritten signatures possibly the most com- mon mechanism ever used. With the shift to digital communications, the same guarantees that exist in real world transactions are expected from electronic ones as well. Non-repudiation is thus a desired property of cur- rent electronic transactions, like those carried out in Internet banking, e- commerce or, in general, any electronic data interchange scenario. Digital evidence is generated, collected, maintained, made available and verified by non-repudiation services in order to resolve disputes about the occurrence of a certain event, protecting the parties involved in a trans- action against the other's false denial about such an event. In particular, a digital signature is considered as non-repudiation evidence which can be used subsequently, by disputing parties or by an adjudicator, to arbitrate in disputes.

    Network Working Group D. Pinkas Request for Comments: 5126 Bull SAS Obsoletes: 3126 N. Pope Category: Informational Thales eSecurity J. Ross Security and Standards February 2008 CMS Advanced Electronic Signatures (CAdES) Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This document defines the format of an electronic signature that can remain valid over long periods. This includes evidence as to its validity even if the signer or verifying party later attempts to deny (i.e., repudiates) the validity of the signature. The format can be considered as an extension to RFC 3852 and RFC 2634, where, when appropriate, additional signed and unsigned attributes have been defined. The contents of this Informational RFC amount to a transposition of the ETSI Technical Specification (TS) 101 733 V.1.7.4 (CMS Advanced Electronic Signatures -- CAdES) and is technically equivalent to it. The technical contents of this specification are maintained by ETSI.
