摘要：
A method for securely handling processing of information in a chip may include randomly selecting one of a plurality of data processes based on a random process index. A time interval may be randomly allocated on the chip, for processing the randomly selected one of the plurality of data processes. When the randomly allocated time interval has elapsed, the randomly selected one of the plurality of data processes may be initiated. The randomly selected one of the plurality of data processes may include one or both of accessing data and acquiring the data. Data may be verified by the randomly selected one of the plurality of data processes prior to the processing of the data. The data may be verified utilizing at least one digital signature verification algorithm, such as a Rivest-Shamir-Adelman (RSA) algorithm and/or a secure hash algorithm (SHA-1).
