    摘要: An efficient protocol for retrieving cryptographic evidence may be selected by evaluating a local policy and a number of relevant factors. Furthermore, updated cryptographic evidence may be prefetched during a time period in which there is a low volume of requests for cryptographic evidence. This low volume time period may be defined, approximately, as an overlapping window in which both a first cryptographic evidence publication and a second cryptographic evidence publication are valid.

    摘要: An update process is used to update root certificates in a root certificate store of a client computer, maintaining the integrity of the existing root certificates as well as any new root certificates. In accordance with certain aspects, the integrity of a certificate trust list identifying one or more root certificates is verified. The root certificate store of the client computer is modified in accordance with the certificate trust list if the integrity of the certificate trust list is verified.

    摘要: Systems and methods for managing multiple keys for file encryption and decryption may provide an encrypted list of previously used keys. The list itself may be encrypted using a current key. To decrypt files that are encrypted in one or more of the previous keys, the list can be decrypted, and the appropriate previous key can be retrieved. To re-key files, an automated process can decrypt any files using previous keys and encrypt them using the current key. If a new current key is introduced, the prior current key can be used to decrypt the list of keys, the prior current key can be added to the list, and the list can be re-encrypted using the new current key.
