    摘要: A method and apparatus for encoding a purpose into a digital signature, where purpose and digital signature bound into an extended digital signature. The extended digital signature capability binds a purpose description identifying the purpose for the digital signature so that when affixed to a digital signature, the digital signature cannot be employed for improper purposes. A hash function is used to generate a hash value from the purpose description. The hash value is used in a digital signature function to bind the purpose to a digital signature. The extended digital signature can be verified for validity by comparing it to a hash value. In an electronic transaction, the extended digital signature can allow a purpose to be bound with the digital signature so that improper or unauthorized transactions are detected and disallowed.

    摘要: A method and system for maintaining integrity and confidentiality of pages paged to an external storage unit from a physically secure environment. An outgoing page is selected to be exported from a physically secure environment to an insecure environment. An integrity check value is generated and stored for the outgoing page. In one embodiment, this takes the form of taking a one-way hash of the page using a well-known one-way hash function. The outgoing page is then encrypted using a cryptographically strong encryption algorithm. Among the algorithms that might be used in one embodiment of the invention are IDEA and DES. The encrypted outgoing page is then exported to the external storage. By virtue of the encryption and integrity check, the security of the data on the outgoing page is maintained in the insecure environment.

    摘要: In one embodiment, a method is described to secure transfer data from one location to another for storage in an electronic component. The transfer occurs with part of the data routed to a first destination and the remaining data routed to a second destination. The data routed to the first destination is for securely loading a current sort encrypted key (SEK) and a next SEK into memory of the electronic component. The data routed to the second destination includes a private key which is recovered using the current SEK and the next SEK.
