Security and Legal Issues in VPSign
Regulatory Issue
Electronic signature solutions must meet unique territorial and industrial regulatory challenges. Existing solutions suffer from limitations that the VPad patented solution aims to avoid. VPSign has already proved their approach in Israel and Italy by meeting regulatory demands where other vendors have failed.
Patents
VPSign's US preliminary patent was presented in 2005 and approved in 2011. It covers many other solutions offered during this time.
Terminology
Certification Authority - In cryptography, a certificate authority or certification authority (CA) is an entity that issues digital certificates for use by other parties. It is an example of a trusted third party. CAs are characteristic of many public key infrastructure (PKI) schemes.
X.509 - In cryptography, X.509 is an ITU-T standard for a public key infrastructure (PKI) for single sign-on (SSO) and Privilege Management Infrastructure (PMI). X.509 specifies, among other things, standard formats for public key certificates, certificate revocation lists, attribute certificates, and a certification path validation algorithm.
ITU-T - The Telecommunication Standardization Sector (ITU-T) coordinates standards for telecommunications on behalf of the International Telecommunication Union (ITU). The ITU-T is based in Geneva, Switzerland.
PKI - A Public Key Infrastructure (PKI) certificate allows someone to combine their digital signature with a public key and an identifier, such as their full name. A PKI certificate is a security mechanism for public keys, used to allow computer users to show that they own the public keys they claim.
