  • Patent number: 10708478
    Abstract: Improved fluoresced imaging (FI) and other sensor data imaging processes, devices, and systems are provided to enhance display of different secondary types of images and reflected light images together. Reflected light images are converted to a larger color space in a manner that preserves the color information of the reflected light image. FI or secondary images are transformed to a color range within the larger color space, but outside the color area of the reflected light images, allowing the FI or secondary images to be combined with them in a manner with improved distinguishability of color. Hardware designs are provide to enable real-time processing of image streams from medical scopes. The combined images are encoded for an electronic display capable of displaying the larger color space.

  • Publication number: 20200004552
    Abstract: Detailed herein are systems, apparatuses, and methods for a computer architecture with instruction set support to mitigate against page fault- and/or cache-based side-channel attacks. In an embodiment, an apparatus includes a decoder to decode a first instruction, the first instruction having a first field for a first opcode that indicates that execution circuitry is to set a first flag in a first register that indicates a mode of operation that redirects program flow to an exception handler upon the occurrence of an event. The apparatus further includes execution circuitry to execute the decoded first instruction to set the first flag in the first register that indicates the mode of operation and to store an address of an exception handler in a second register.

  • Publication number: 20190065406
    Abstract: In a method for protecting extra-enclave communications, a data processing system allocates a portion of random access memory (RAM) to a server application that is to execute at a low privilege level, and the data processing system creates an enclave comprising the portion of RAM allocated to the server application. The enclave protects the RAM in the enclave from access by software that executes at a high privilege level. The server application obtains a platform attestation report (PAR) for the enclave from the processor. The PAR includes attestation data from the processor attesting to integrity of the enclave. The server application also generates a public key certificate for the server application. The public key certificate comprises the attestation data. The server application utilizes the public key certificate to establish a transport layer security (TLS) communication channel with a client application outside of the enclave. Other embodiments are described and claimed.

  • Patent number: 9646166
    Abstract: A method for encrypting a database includes the following step. Keywords in the database are encrypted to obtain encrypted search tags for the keywords. A table of reverse indices is generated for the encrypted search tags. A table of cross keyword indices is generated. A method for searching in an encrypted database includes the following steps. A search is formulated as a conjunct of two or more atomic search queries. One of the conjuncts is selected as a primary atomic search query. Search capabilities are generated for a secondary atomic search query using the primary atomic search query and the secondary atomic search query. Such methods mask query data and the actual composition of the database to reduce computation complexity and privacy leakage.

  • Patent number: 8135766
    Abstract: A random number generator (RNG) resistant to side channel attacks includes an activation pseudo random number generator (APRNG) having an activation output connected to an activation seed input to provide a next seed to the activation seed input. A second random number generator includes a second seed input, which receives the next seed and a random data output, which outputs random data in accordance with the next seed. An input seed memory is connected to the activation seed input and a feedback connection from the activation output so that the next seed is stored in the input seed memory to be used by the APRNG as the activation seed input at a next startup cycle.

  • Patent number: 8108940
    Abstract: The present invention relates to a method for protecting user data from unauthorized access, the method comprising the steps of, on a data processing system: maintaining said user data in encrypted form stored on a second storage, when loading an operating system using an operating system loader: receiving in a first disk key transmission step from a first user system a symmetric user key that is only accessible by the data processing system if the operating system loader has been started on behalf of said first user system, wherein the symmetric user key is received sealed to a combination of the operating system loader and a user identifier corresponding to said first user system in said first disk key transmission step; accessing the symmetric user key, if the operating system loader has been started on behalf of said first user system; decrypting in a user data decryption step said user data using the symmetric user key, maintaining said symmetric user key in a volatile memory.

  • Patent number: 8087090
    Abstract: An access control system and method includes a risk index module which computes a risk index for a dimension contributing to risk. A boundary range defined for a parameter representing each risk index such that the parameter above the range is unacceptable, below the range is acceptable and in the range is acceptable with mitigation measures. A mitigation module determines the mitigation measures which reduce the parameter within the range by mapping the effectiveness of performing the mitigation measures to determine a residual risk after a mitigation measure has been implemented.

  • Patent number: 8020193
    Abstract: Computer implemented methods (200) for protecting web based applications (110, 114) from Cross Site Request Forgery (CSRF) attacks. The methods involve (204) classifying each resource offered by a web server application as a CSRF-protected resource or a not-CSRF-protected resource. The methods also involve (214, . . . , 222) performing a user authentication, (224) initializing an authentication-token, and (226) initializing a CSRF protection secret that is used to validate CSRF protection parameters contained in resource identifiers for the resources. The methods further involve (228) performing a server-side rewriting process (300) to add the CSRF protection parameter to the resource identifiers for the resources and/or (230) performing a client-side rewriting process to add the CSRF protection parameter to a resource identifier for a second resource (e.g., a resource created at a client computer (102)).
