OS +Security Quick Start

Architecture

OS Security includes the following +collections:

Authorisation contains User Prompt Service (UPS) +component that provides standard interfaces for the device creators to set +policies that determine if requests made by applications to access system +services, such making telephone calls, need confirmation from the user.
Security +and Data Privacy Tools contains Security +Config and Security +Tools components. Security Config contains security ROM build-time +configuration files. Device creators use the configuration files to customize +the behavior of security components. Security Tools comprises of certapp tool +that creates, augments, dumps and debugs certificate stores. It also dumps +certificate files in human-readable form.
Crypto +Management Libraries provides interfaces for management of tokens used +for secure authentication, such as cryptographic keys and certificates. It +contains CryptoToken +framework to provide interfaces for managing cryptography certificates, +keys and certificate applications.
Crypto +Libraries contains a Weak CryptoSPI and Strong CryptoSPI components +together called as CryptoSPI framework. The framework provides software-based +implementations of cryptographic algorithms. It allows device creators to +include alternative implementations as plug-in DLLs.
Crypto Plug-ins contains +CryptoSPI Plug-ins component. These are plug-ins to the Crypto +Libraries' Crypto SPI framework. It provides software-based implementations +of cryptographic algorithms for encryption, decryption, hash and random number +generation.
Crypto +Services provides interfaces to handle cryptographic keys and certificates. +It contains Certificate +and Key Management, File-Based +Certificate and Key Stores, ASN-PKCS Root Certificates and +OpenSSL components.

The following diagram shows the OS Security's components grouped +into collections, which are shown as white boxes:
