What are Hardware Security Modules (HSMs)?
What is a Hardware Security Module (HSM)?
Hardware security modules (HSMs) are hardened, tamper-resistant hardware devices that secure cryptographic processes by generating, protecting, and managing keys used for encrypting and decrypting data and creating digital signatures and certificates. HSMs are tested, validated and certified to the highest security standards including FIPS 140-ii and Common Criteria. Entrust is a leading global provider of HSMs with the nShield Full general Purpose HSM product family.
HSMs enable organizations to:
- Meet and exceed established and emerging regulatory standards for cybersecurity, including GDPR, eIDAS, PCI DSS, HIPAA, etc
- Achieve college levels of data security and trust
- Maintain high service levels and business agility
What is HSM as a service or Deject HSM?
HSM as a service is a subscription-based offer where customers can apply a hardware security module in the cloud to generate, admission, and protect their cryptographic key cloth, separately from sensitive data. The service offering typically provides the same level of protection equally an on-premises deployment, while enabling more flexibility. Customers can transfer CapEx to OpEx, enabling them to only pay for the services they need, when they need them.
nShield as a Service uses defended FIPS 140-2 Level iii certified nShield HSMs. The offer delivers the aforementioned full set of features and functionality as on-premise nShield HSMs, combined with the benefits of a cloud service deployment. This allows customers to fulfill either their deject first objectives or deploy a mix of on-premise and as-a-Service HSMs, with maintenance of the as-a-Service appliances performed past the experts at Entrust.
Why should I employ an HSM?
Cryptographic operations like encryption and digital signing are worthless if the private keys they use are not well protected. Attackers today have grown much more sophisticated in their power to locate private keys that are stored or are in use. HSMs are the gold standard for protection of private keys and associated cryptographic operations, and enforce the policy defined by the using organization for users and applications that tin can admission those keys. HSMs can be used with many different types of applications that perform encryption or digital signing. The height ten use cases for HSMs, from the 2021 Ponemon Global Encryption Trends Study (May 2021), are shown in the figure beneath.
What value does an HSM provide?
HSMs enhance and extend the security of a wide range of applications that perform encryption and digital signing. The tabular array below describes the added value of HSMs for a set of the most mutual use cases.
Use Case
Value of HSM to Utilise Instance
Maintain control of keys and data in the cloud; secure containerized applications
Protect disquisitional PKI root and CA signing keys
Address insider threats and simplify access to secrets for DevOps
Enhance encryption central protection for data in transit and storage
Enforce central direction policy across multiple clouds and applications
Protect keys that ensure software integrity and enable legally binding transactions
Secure master TLS/SSL encryption keys
Create trusted identity credentials
Protect the keys that create and sign payment credentials
What is a Root of Trust?
Root of Trust (RoT) is a source that tin always be trusted within a cryptographic system. Considering cryptographic security is dependent on keys to encrypt and decrypt data and perform functions such as generating digital signatures and verifying signatures, RoT schemes generally include a hardened hardware module. A principal case is the hardware security module (HSM) which generates and protects keys and performs cryptographic functions inside its secure environment.
Because this module is for all intents and purposes inaccessible outside the calculator ecosystem, that ecosystem can trust the keys and other cryptographic information it receives from the root of trust module to be authentic and authorized. This is specially important equally the Internet of Things (IoT) proliferates, considering to avoid being hacked, components of calculating ecosystems need a way to decide information they receive is authentic. The RoT safeguards the security of data and applications and helps to build trust in the overall ecosystem.
RoT is a critical component of public key infrastructures (PKIs) to generate and protect root and certificate authority keys; code signing to ensure software remains secure, unaltered and accurate; and creating digital certificates and automobile identities for credentialing and authenticating proprietary electronic devices for IoT applications and other network deployments.
What is random number generation?
Random number generation (RNG) refers to the random numbers created by an algorithm or device. It is of import that cryptographic keys are created using a certified source of random numbers, which is a challenging problem for software-based systems.
When the source of entropy for a random number generator is derived from software-based measurements, information technology cannot be guaranteed that the entropy volition non be anticipated, or able to be influenced. An HSM uses a hardware-based source of entropy for its RNG that has been verified to provide a practiced source of entropy in all normal operating conditions. This is important for use cases like BYOK (Bring Your Own Key), which allows users to create and manage keys that they upload to deject service providers.
