A method for securely handling processing of information includes, in a chip, selecting one of a plurality of data processes based on a random index. After a randomly allocated time interval has elapsed, the selected one of the plurality of data processes may be initiated. The selected one of the plurality of data processes may include accessing data and/or acquiring the data. Burstiness of the data may be approximately equal to burstiness of data acquired by at least one of a plurality of clients on the chip. Data may be verified by the selected one of the plurality of data processes prior to the processing of the data.

Method and system for random data access for security applications

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).

Methods and systems for random data access for security applications are disclosed and may comprise generating on a chip, a random process index. A data process may be randomly selected on the chip utilizing the generated random process index. A time interval may be randomly allocated on the chip. After the time interval, the randomly selected data process may initiate processing of data. The processing of the data may comprise accessing the data and/or acquiring the data. The data may be verified by the selected data process prior to the processing of the data. The data may be verified utilizing a digital signature verification algorithm, for example.
