Digital Communication & End-to-end Encryption

Telecommunication networks underpin communication, collaboration and media platforms used by millions of organisations and billions of individuals every day, making use of various types and methods of communication as an everyday part of life.

These vast amounts of data in motion, produced by everything from voice calls, smart meters and connected IoT devices, messaging apps or email, collaboration tools to media streaming services, make telecom networks a target for cybercriminals who can intercept and manipulate communications, breach confidentiality and data integrity .

Ensuring the security of communication, including the capability to encrypt sensitive traffic, has long been a critical cornerstone of the telecom industry. Consumers expect their privacy to be protected and providers expect to be able to safeguard themselves and their customers from various types of threats.

Utimaco provides proven cybersecurity solutions. One important part is the encryption of  sensitive data which in turn is rendered indecipherable to all except authorized recipients with the provision to decrypt data to ensure message confidentiality and authenticity. A second part takes care of the provision of digital identities to humans and systems, with the objective to provide gated system access to authorized persons and solutions as well as to enable provable and non-repudiable legal activities. In conjunction with intelligent 5G communication, the solutions enable modern day communication and service level agreements for dynamic service offerings in a highly secure framework.

Trusted Processes

Trusted Digital End-to-End Processes


Digital Signatures

Digital signatures leverage PKI certificates to offer the highest levels of security for regulated and sensitive document use cases such as insurance applications, claims and changes to policies. In compliance with regulations such as eIDAS, they also provide legal assertion.

Multi Factor Authentication

Multi-factor authentication securely restricts access to the service infrastructure and reliably identifies the user. Hardware security modules (HSMs) generate, manage and store the secure cryptographic keys required for authenticating a user or device in a broader network.

Database Encryption

Effective database security has become increasingly important- without a comprehensive strategy, a great deal of sensitive data could be at risk. Database encryption using HSMs protects and secure sensitive data.

Public Key Infrastructure (PKI)

Security of 5G device-to-device communication requires a secure PKI-Infrastructure to manage encryption of mobile traffic, ensuring confidentiality, integrity, and authenticity of sensitive information. Encrypting data at rest and in transit guards it against theft or tampering, and guarantees that digital identity provides secure authentication of users, connected devices and applications to protect against fraud. A PKI solution also turns certificate management scalable to support the networking power of 5G, meeting growing IoT requirements.

5G Technology

With 5G networks being built on software based models, ensuring security from the infrastructure layer to the application layer is an essential factor for consideration. HSM-protected 5G creates secure channels between devices and the telecoms infrastructure.

Code signing

HSM-based code signing is the most secure way to physically and digitally secure code. If the code is tampered with after signing, then the signature will be invalid and no longer trusted. Signing keys are protected and can only be accessed by authorized users or systems.

Tokenization of Payment Data

Tokenization turns financial data, such as a payment card number, into an unrecognizable string of characters that will provide no value to the hacker even if breached. It is a strong tool to protect communication and transactions along the digital value chain.

Payment processing

From Merchant’s Points of Sales, mobile devices and ATMs, Utimaco covers the complete chain of PIN encryption, authorization, PIN translation and Key Management through Acquirers, Switches and Issuers. Utimaco’s Atalla Division invented encrypted PIN and ATM messages in the 1970s and has led the evolution of standards and innovation ever since.

Cloud Service Architecture

A hybrid cloud solution embraces architectures of decentralized manufacturing processes in an agile, seamless, traceable and secure way. Data security and privacy regulations require that data transfer from and to the Cloud service as well as at rest is continuously encrypted.

Multi-cloud Key Management

Bring-your-own-key concept allows to securely and remotely generate & manage keys across the hybrid cloud and the complete life cycle, retaining full control over the data, and assuring data security and privacy at any time and at any location.

Post Quantum Crypto Agility (Future Proofs and PQC)

At this time, no quantum computer can run quantum algorithms, however once they are able to, these computers will decimate the security infrastructure of the digital world. Post-quantum crypto-agility is a necessity for the telecommunications infrastructure to be able to evolve in the advent of a new generation of attacks and consequently evolving cryptographic standards and algorithms.
