US 8,477,932 B1 · System and/or method for encrypting data

Abstract

In one embodiment, progress of an encryption process may be tracked. This may comprise, for example, storing progress of an encryption process so that the encryption process may be resumed after an interruption of the encryption process. As such, progress data may identify a point in the encryption process so that encryption may be resumed from that point. In at least one embodiment, storing progress of an encryption process may comprise storing and/or otherwise providing the last segment of data that was encrypted and/or the last segment of data that was not encrypted. Additionally, a data structure, may provide a capability to mark or indicate a point of interruption of the encryption process and provide data that may be utilized to resume from the point of interruption the overall encryption process.

Dependent claims

A method, comprising:

initiating an encryption process by a processor to encrypt a portion of data that is designated for encryption;
storing progress data in a data structure relating to the encryption process;
toggling a first progress data in the data structure to a first updated data value to indicate initiation of the encryption of the portion of data;
toggling a second progress data to a second updated value to indicate completion of the encryption of the portion of data;
in response to an interruption in the encryption process, locating a segment of data having the first progress data toggled to the first updated value and the second progress data not toggled to the second updated value as an indication of a point of interruption;
and
resuming the encryption process from the point of interruption located by the second progress data.
