PKI Infrastructure and Electronic Signature

Protect Your Digital Identity with PKI

Public Key Infrastructure (PKI) is a security framework that enables secure communication, authentication, and data integrity. As digital transformation accelerates, PKI has become a foundational security pillar for governments, organizations, and individuals, ensuring trust and protection across digital interactions.

Key Benefits of PKI

High Level of Security
Strong encryption and authentication mechanisms protect data from unauthorized access and manipulation. Encryption ensures that only authorized parties can read the data, while digital signatures guarantee the integrity and authenticity of electronic documents.
Reliable Digital Identification
PKI technologies enable secure verification of the identity of users, devices, and servers. Digital certificates play a key role in preventing phishing and identity fraud, and they support secure authentication, including multi-factor authentication methods.
Legal Validity and Compliance
PKI technologies enable legally binding electronic signatures, which is particularly important for e-business and e-government services. Qualified electronic certificates have the same legal effect as handwritten signatures.
Secure Electronic Transactions
In electronic transactions, PKI provides security for online payments and e-commerce, reducing the risk of fraud. Banks and financial institutions use PKI for secure client authentication, while data tokenization and encryption provide additional protection for financial transactions.
Scalability and Flexibility
PKI systems are scalable and flexible, making them suitable for both small and large organizations. Cloud-based PKI solutions enable straightforward deployment, while automated certificate management simplifies administration in large-scale environments.
Integration with Multiple Systems
PKI can be integrated with VPNs, email systems, IoT devices, blockchain technologies, and zero trust architectures.

Key benefits of using electronic signatures

Authenticity

They ensure that the signature originates from a verified signer.

Integrity

They ensure that the document has not been altered after signing.

Non-repudiation

They ensure that the signer cannot deny having signed the document.

Legal Validity

They are recognized under regulatory frameworks such as eIDAS.

Efficiency

They eliminate the need for physical signatures, accelerating digital processes.

Improve Your Business by Introducing Electronic Signatures into Your Processes

One of the most important applications of PKI systems is electronic signatures, which function as the digital equivalent of a handwritten signature or a notary seal. They ensure that the signed content is authentic and has not been altered.

Electronic signatures are used across various industries and sectors to accelerate processes, improve security, and reduce reliance on paperwork. Their adoption is widespread in both the public and private sectors, enabling legally valid and secure digital transactions.

Challenges and Vulnerabilities of Modern PKI Systems

PKI systems form the foundation of digital trust and security, but they face ongoing challenges.

Complexity of PKI Implementation and Maintenance
Implementing and maintaining PKI systems is technically complex and requires specialized expertise.
Certificate Lifecycle Management
We have developed our own trusted system for managing the full lifecycle of certificates and smart cards, and we provide services for their customization and integration into your existing infrastructure.
Compliance and Regulatory Challenges
PKI systems must comply with strict security and data protection regulations that continue to evolve. Failure to meet regulatory requirements can result in legal penalties, financial losses, and reputational damage.
Cryptographic Vulnerabilities
Organizations that implement stronger encryption standards, enhanced CA procedures, and crypto-agility will be better prepared for future security challenges.
Post-Quantum Cryptography
The emergence of quantum computing represents a serious challenge, as quantum computers have the potential to compromise many of the cryptographic algorithms on which today’s PKI is based. Organizations that rely on long-term digital signatures or store encrypted sensitive data must begin taking action now to prepare for quantum-resistant cryptography.
Scalability Challenges
PKI systems must be scalable to support large numbers of certificates, high volumes of real-time certificate validation requests, and automated certificate issuance and renewal—while maintaining low latency for critical applications.
Certificate Revocation
Efficient revocation of compromised or expired certificates is not always immediate, which creates a security risk. Delays in revocation can result in situations where compromised certificates are still treated as valid, creating potential security gaps.

Qualified Electronic Certificate Issuance System
Public Administration

Challenges:

The Indirect Taxation Authority needed to address several major challenges for its clients, including ensuring the integrity of electronic documents, guaranteeing their legal validity, and providing strong authentication and user identity verification. At the time, no such service existed in Bosnia and Herzegovina.

Solution:

The Indirect Taxation Authority implemented a robust PKI system that successfully passed accreditation by an authorized conformity assessment body for qualified trust service providers, in accordance with the requirements of the eIDAS Regulation (EU) 910/2014. As a result, it became the first government institution in Bosnia and Herzegovina to provide qualified electronic certificate issuance services. In addition to addressing the challenges that motivated this project, the key benefit of the system implementation was the creation of the necessary conditions for all business entities in Bosnia and Herzegovina to begin using qualified electronic certificates.

Challenges:

Although it represents the most secure way of using electronic certificates, smart card–based signing has several drawbacks. These include limited access to physical signing devices, lack of mobility and flexibility, and complexity that creates technical barriers for users. The main challenge faced by the Indirect Taxation Authority was adoption by business users, primarily due to the complexity of integrating smart card–based signing with existing business systems.

Solution:

By introducing a remote signing service, the Indirect Taxation Authority enabled its clients to use electronic signatures without the need for a smart card.
Under the eIDAS Regulation (EU) No 910/2014, remote signing is defined as a qualified trust service that allows users to create a qualified electronic signature without having direct control over the private key. The private key is securely managed by a Qualified Trust Service Provider (QTSP) within a controlled environment. This project enabled all clients of the Indirect Taxation Authority—namely all business entities in Bosnia and Herzegovina—to integrate their business systems with the ITA’s remote signing system, thereby enabling the use of qualified electronic signatures.
