20150304107 | Extracting Entropy from Machine Vibration - Generating a pool of random numbers for use by computer applications. Vibration sensors are placed throughout a machine and collects information theoretic entropy data from the measurement of the vibration sensors. The data is then filtered and added to an entropy pool. Applications needing a random number may acquire a number from the pool. A method, computer program product and system to generate the pool are provided. | 2015-10-22 |
20150304108 | Encryption Key Destruction For Secure Data Erasure - Techniques for encryption key destruction for secure data erasure via an external interface or physical key removal are described. Electrical destruction of key material retained in a memory of a storage device renders the device securely erased, even when the device is otherwise inoperable. The memory (e.g. non-volatile, such as flash) stores key material for encrypting/decrypting storage data for the device. An eraser provides power and commands to the memory, even when all or any portion of the device is inoperable. The commands (e.g. erase or write) enable zeroizing or destroying the key material, rendering data encrypted with the destroyed key material inaccessible, and therefore securely erased. Alternatively, the memory is a removable component (e.g. an external security device or smartcard) coupled to the device during storage operation. Removing and physically destroying the memory renders the device securely erased. The device and/or the memory are sealed to enable tamper detection. | 2015-10-22 |
20150304109 | CONTOUR ENCRYPTION AND DECRYPTION - A method of encrypting information includes converting an information sequence represented as a strings of bits into a curvilinear coding system, where each element of the curvilinear coding system corresponds to a sub-sequence of successive same-valued bits, converting said curvilinear coding system into a at least one closed curve, and embedding said at least one closed curve in a 2-dimensional pattern. A method for decrypting information includes extracting at least one closed curve from a digitized 2-dimensional pattern, and converting the at least one closed curve into an information sequence represented as a string of bits. | 2015-10-22 |
