A method and apparatus for analyzing side-channel security vulnerabilities in a digital device. A first time sequence of measurements of side-channel related phenomena of the digital device, such as power draw or electromagnetic emissions is obtained. A second time sequence of debug outputs of the digital device, such as program counter contents or other device processor or register states, is obtained. The first time sequence and the second time sequence are obtained based on a common time reference, and thus correlated in time. A controller can provide a common timing signal to measurement equipment obtaining the first time sequence and to a debug tool obtaining the second time sequence, and the common time reference can be correspond to the common timing signal.

Method and apparatus for analyzing side channel-related security vulnerabilities in digital devices

A system and method for communicating data between a first software and a second software located on first and second devices, respectively, has a hardware driver and memory associated with each device. Each communication of data from the first software to the second software allocates memory to manage data to be communicated from the first software to the second software, provides memory allocation information to the hardware driver associated with the first software, and transmits the data from the first hardware driver to the second hardware driver for delivery to the second software via the memory associated with the second software.

A secure generic encryption system for nonsecure datapaths comprises a format-specific adaptation layer/data path for receiving and processing nonsecure content data; an authentication engine located within a security perimeter and coupled to an external communication interface for authentication and supplying the format-specific adaptation layer/data path, located outside the security perimeter, with an output signal indicating whether authentication is successful; and a generic encryption module located within the security perimeter and coupled (1) to the authentication engine for receiving from the authentication engine initialization vectors, encryption keys, and the output signal indicating whether authentication is successful, and (2) to the format-specific adaptation layer/data path for (a) receiving a read signal from the format-specific adaptation layer/data path, and (b) providing the format-specific adaptation layer/data path with a data-available signal to indicate whether data is available to be read.

An embodiment of a method and apparatus for ciphering data. Data is provided for ciphering. The data is ciphered in a plurality of steps. For each step, determining an encoding for error detection of the data being processed within the step. Determining an output error detection encoding for the step. Processing data of the round to provide output error detection encoding. Then, verifying the encoding against a determined output error detection encoding. If the output error detection encoding is not the same as the determined error detection encoding, providing a signal indicating the presence of an error within the cipher process.

Method and apparatus for cipher detection

What is disclosed is an embodiment of a method for ciphering data. Data is provided for ciphering thereof. The data is ciphered in a plurality of steps. For each step, an encoding for error detection of the data for being processed within the step is determined. An output error detection encoding for the step is determined. The data for being processed within the round is processed to provide output error detection encoding which is then verified against the determined output error detection encoding. When the output error detection encoding is other than same as the determined error detection encoding, providing a signal indicative of an error within the cipher process.
