Patent ID: 7184549

Claim:
An encrypting apparatus encrypting first processing data and second processing data comprising: a memory for storing a status of an encrypting process of a particular processing data, wherein the encrypting apparatus starts an encrypting process of the second processing data before an encrypting process of the first processing data is completed, thereby interrupting the encryption process of the first processing data between two logically continuous data elements in the first processing data, the encrypting apparatus causes the memory to store the status of the encrypting process of the first processing data when the encrypting apparatus starts the encrypting process of the second processing data, the encrypting status of the encrypting apparatus is returned to the status of the encrypting process of the first processing data stored in the memory when the encrypting apparatus restarts encrypting the first processing data, and the first processing data are a first logically continuous set of data elements, and the second processing data are a second logically continuous set of data elements.
