Crypto Wallet Security Services

The security of crypto wallets depends directly on the components used and the implementation of their hardware, software, and communication protocols. Independent, third-party validation and advice by security experts is therefore critical to ensure that crypto wallets are robust against relevant threats.

Context

According to Allied Market Research, the global hardware wallet market size will grow at a compound annual growth rate of 24.0 % from 2021 to 2028.
Both custodial and non-custodial wallet solution developers need to secure their business and build user confidence in how their crypto assets are protected. We can give you that confidence.

Our mission

We help companies build secure, validated crypto wallet solutions

Gain valuable insights that will drive your success

Expertise you can trust

We ensure the security and robustness of crypto wallets  based on more than 25 years of research, analysis, development, and operational excellence in security. Our IoT Security Labs and security experts use state-of-the-art equipment and advanced techniques to validate the security of your products and give you advice you can use.

How we work together

We work with you to assess your security threats and opportunities and help you create a crypto asset wallet - whether it’s a physical one, an app, or a service - that protects keys for cryptocurrency transactions. We provide security designs, security assessments and pre-certification support for government schemes like CSPN.

APPROACH

3-Steps to a secure crypto wallet

How do we help you gain customer confidence and ensure the business success?

Threat Assessment

We identify attack vectors, followed by evaluation of threats based on likelihood, complexity, and business impact. This results in a comprehensive view of risks that should be protected against.

Architecture review

We validate the presence and efficacy of security controls.
We highlight any security risks associated with the architecture and with the implementation of critical features.

Lab Evaluation

We provide concrete proposals for threat mitigation measures. We review the security of source code for software wallets and conduct pen tests on virtual ledgers and apps. We perform hardware attacks on secure elements for hardware cold Personal Security Devices.

Method

Main focus areas to secure crypto wallets

We examine five key elements of your wallet design

1
Security of identification and end-user authentication mechanisms (e.g. PIN, user interface).
2
Confidentiality, integrity and availability of the wallet, crypto assets and secret keys (e.g. plausible deniability, genuine PSD, deterministic RNG, seed generation, transaction signature).
3
Robustness of cryptographic primitives implementation (e.g. side-channel attacks due to bias in key handling algorithms).
4
Connectivity, communication patterns and protocols, offline constraints.
5
Security lifecycle (e.g. provisioning, secure software / firmware updates, decommissioning / revocation).

Side Channel Analysis

Side Channel Analysis refers to the use of information leakage related to an event which is obtained through secondary phenomenon, such as changes in power consumption or magnetic field emission.

When protections such as masking are not sufficiently efficient, it can lead to the recovery of secrets from the operation of an electronic device. Often these secrets are cryptographic keys.
