E-signature, encryption

Solution based on Axidian CertiFlow for efficient digital certificates security maintenance that allows to replace hardware devices



In recent years, employers have been paying special attention to organizing and protecting remote workflow. Enterprise mobility does have certain benefits: employees can access required services at any time and take care of urgent tasks even when they are away on vacation or sick leave. And this can boost workflow efficiency and team productivity.

Leadership at many companies, large and small, try to make the most of remote access tools. However, they still need to handle a variety of tasks related to digital certificates:

  • Two-factor authentication based on certificates (for example, logins to the operating system, VPN authentication)
  • Website verification (SSL certificates)
  • Network resource verification (for example, routers)
  • Preventing unauthorized software alterations (code signing)
  • Data encryption (IPsec)
  • Encryption and signature for emails
  • Digital signature for electronic document flow, etc.

Two-factor authentication and data encryption are especially important in the case of remote work when workstations are not protected by the corporate perimeter and employees may use unsafe public networks to connect to corporate services.

Digital certificates may have multiple advantages but they do come with one essential requirement: you need a secure device to store the key information and perform all cryptographic operations. A classic solution would be to use a hardware device — a smart card or a USB token.

However, in the context of enterprise mobility, the use of smart cards and tokens (despite their obvious strengths in terms of information security) can have serious limitations:

  • Logistics related to the delivery of hardware devices to mobile workstations
  • Costs related to purchasing hardware devices and readers
  • Lack of smart card readers or their failure
  • Issues with quick access to enterprise resources whenever a hardware device is lost or broken

The best solution would be to introduce virtual smart card technology that does not require removable devices for using digital certificates. Virtual smart cards can also be used together with classic PKI tokens both on a regular basis or ad-hoc whenever you need a virtual replacement for your hardware device, for example, when its delivery is in progress.


Maintaining the security of digital certificates beyond the corporate perimeter without using personal hardware devices poses a challenge to all technologies involving digital certificates.

One leading-edge development in this field has been the cloud- or network-based electronic signature stored on a secure server instead of a user’s PKI token. What is being protected in this case is the connection between a user’s computer and the secure server with key information.

Another popular solution is Trusted Platform Module when a dedicated microprocessor is used for secure storage of key information and performance of cryptographic operations. This module is a native component of a user’s device, be it a smartphone or a computer.

Axidian CertiFlow supports both technologies and offers its own mechanism to enable online delivery of certificates to user workstations. The proposed solutions can be used as a high-quality alternative to hardware devices or as a temporary solution whenever a token or smart card is lost or broken.


Trusted Platform Module, secure storage of key information

Trusted Platform Module (TPM) is a secure microprocessor designed to create and store cryptographic keys and perform cryptographic operations. TPM does not depend on Windows and has its own non-volatile memory that can retain data after power interruptions.

There are different types of TPM implementations:

  • A separate chip on the motherboard
  • A chip integrated into the processor
  • Firmware

The module lets you solve various tasks, including data encryption on your hard drive, user authentication, tamper-proofing, protection of license rights, etc.

You can use Axidian CertiFlow to issue a new virtual TPM device in the user console and manage its entire lifecycle. This means it can be updated, temporarily disabled, revoked, and assigned a new PIN code.

Axidian CertiFlow will monitor and run audits for all user activity with TPM devices. It can also send notifications to the administrator to alert them about pre-defined events.

Windows Hello for Business, two-factor authentication instead of passwords

Windows 10 and later versions offer a new tool, Windows Hello for Business (WHfB) that replaces passwords with strong two-factor authentication on computers and mobile devices. Windows Hello relies on TPM technology, which guarantees a high level of information security.

This solution lets you store your keys in a secure vault on your computer and simulate authentication at the enterprise workstation by using biometric authentication or a PIN. Relevant key information can also be used to connect to a VPN gateway or enterprise resources that use certificates.

With Axidian CertiFlow, you can create a PIN for WHfB whenever you issue a new device, manage the certificates that will be installed on the virtual card, and update these certificates as needed.

Axidian AirCard Enterprise, a network smart card

Software-based smart cards are delivered to a user’s workstation online, do not require a reader, and can be used on virtual workstations.

This is exactly how Axidian AirCard Enterprise works. Your employees can use it just like they would use a hardware smart card — to sign documents, encrypt data, and complete two-factor authentication. At the same time, they cannot break, lose or forget it at home, while the digital certificate and its private key will be stored on a secure server.

After integration with Axidian Access, an AirCard can also be used for gaining access to corporate applications and programs on a user workstation.
