What type of device is known for generating and storing cryptographic keys while being less susceptible to tampering?

The Hardware Security Module (HSM) is specifically designed to generate, store, and manage cryptographic keys in a secure manner. HSMs are physical devices that provide a high level of protection against tampering, unauthorized access, and misuse of cryptographic keys. They utilize various security features, including secure key generation, secure storage, and cryptographic operations, all performed within the device itself, which minimizes the risk of exposure to external threats.

HSMs are often used in enterprise environments where cryptographic keys are critical for maintaining the confidentiality, integrity, and authenticity of sensitive data. Their ability to perform cryptographic functions away from the host system also ensures that the keys are not at risk of being compromised through software vulnerabilities.

In contrast, while a Trusted Platform Module (TPM) also deals with cryptographic keys and provides secure storage, it is primarily intended for use in computers and devices to enhance platform integrity rather than serving as a standalone key management solution like an HSM does. Other options like Secure Sockets Layer (SSL) and Public Key Infrastructure (PKI), while related to cryptography, do not function as physical devices for key generation and storage, making them less relevant in this context.
