IMPLEMENTATION OF AN INTEGRITY-PROTECTED SECURE STORAGE |
摘要 |
<p>An internal but not integrated security token is provided for a device which comprises a first integrated circuitry comprising a secure processor. The security token is provided by a second integrated circuitry separate from the first circuitry. The second integrated circuitry comprises a secure non-volatile storage. The secure processor communicates information to the second circuitry in a secure manner for the secure information to be securely stored in the secure non-volatile storage, and the second integrated circuitry communicates information stored in its secure non-volatile storage to the secure processor in a secure manner. Communications is secured by means of cryptography. The first integrated circuitry and the second integrated circuitry are internal parts of the device. An initialization method for distributing a secure key to be shared between the circuitries and to be used in cryptography is also disclosed. ® KIPO & WIPO 2008</p> |
