Description

The -keystore framework is an extension of CryptoToken -framework. The framework provides interfaces that must be implemented -to retrieve keys from the key store. It provides the following functionalities:

    -

  • Signing through keys -in signature algorithms such as RSA and DSA

    • -

  • Encrypting and decrypting -operations using keys

    • -

Device creators can use the interfaces provided by the framework -to implement keystore for managing keys.

MCTTokenInterface

-

Provides an interface for the implementation of an appropriate token -(here, token refers to a key).

Keystore framework interfaces

The keystore framework -provides interfaces for the following functionalities:

    -

  • Retrieval of keys:

    MCTTokenObject is used to retrieve a -token specific to implementation of MCTTokenInterface. -The retrieved token object is used to perform cryptographic operations such -as signing, decryption and so on.

    • -

  • Key information:

    CKeyInfoBase forms the base class for CCTKeyInfo. All key store implementations -need to interface with this class for accessing or manipulating key details.

    CCTKeyInfo contains all the relevant -information of a key such as ID, type, size, usage, algorithm, security policy -associated to the key. It's implementation is derived from MCTTokenObject and CKeyInfoBase.

    • -

  • Protection of keys:

    MCTAuthenticationObject provides interface -to control authentication mechanism of the keys. It allows to query and manipulate -authentication objects that are returned as token interface from MCTAuthenticationObjectList. It is accessed -by calling a function of CCTKeyInfo.

    • -

  • Cryptographic operations:

    Signing: MCTSigner provides interface to implement -signing through keys. The framework supports two types of signing algorithms; -RSA and DSA through the MRSASigner and -the MDSASigner classes.

    Decryption: MCTDecryptor provides interface to implement -decryption functionality through keys.

    DH agreement : MCTDH provides interface to implement Diffie -Hellman (DH) key exchange protocol.
