Abstract: There are disclosed systems and methods for creating a self-signed implicit certificate. In one embodiment, the self-signed implicit certificate is generated and operated upon using transformations of a nature similar to the transformations used in the ECQV protocol. In such a system, a root CA or other computing device avoids having to generate an explicit self-signed certificate by instead generating a self-signed implicit certificate.

Abstract: The present disclosure relates to systems and methods for secure communications. In some aspects, a method of signalling an interception time period is described. At least one keying information used by a KMF to regenerate a key is stored. A start_interception message is signaled from an ADMF to a CSCF. A halt_message is signaled from the ADMF to the CSCF.

Abstract: A device and method are provided for a device that communicates security information to a user entering content into the device. In an aspect, the device may access content from a server over a connection through the network. The device displays the content on a user interface of the device. The device detects information entered into a field of the displayed content and evaluates a security state of the device. If the security state is below a security threshold and, if the entered information is identified as protected information based on stored criteria, the device displaying a visual indication on the user interface.

Abstract: A system and method for securing communication across an in-vehicle bus, includes establishing a connection between a gateway in a vehicle and the in-vehicle bus; generating a session key at the gateway within the vehicle; transmitting a public key certificate and ephemeral key to the gateway and an electronic control unit of the vehicle; generating a shared secret at the gateway and the electronic control unit, respectively; encrypting the session key with the shared secret at the gateway; receiving the encrypted session key through the in-vehicle bus at the electronic control unit; and decrypting the encrypted session key based on the shared secret generated at the electronic control unit.

Abstract: Methods, systems, and computer programs for generating cryptographic function parameters are described. In some examples, source code that defines seed information and a pseudorandom function is accessed. A parameter for a cryptographic function by operation of one or more data processors is generated. The parameter is generated from the seed information and the pseudorandom function. The parameter has a larger size in memory than the source code that defines the seed information and the pseudorandom function.

Abstract: An asset management system is provided which comprises one or more controllers, which operate as main servers and can be located at the headquarters of an electronic device manufacturer to remotely control their operations at any global location. The controller can communicate remotely over the Internet or other network to control one or more secondary or remote servers, herein referred to as appliances. The appliances can be situated at different manufacturing, testing or distribution sites. The controller and appliances comprise hardware security modules (HSMs) to perform sensitive and high trust computations, store sensitive information such as private keys, perform other cryptographic operations, and establish secure connections between components. The HSMs are used to create secure end-points between the controller and the appliance and between the appliance and the secure point of trust in an asset control core embedded in a device.

Abstract: Accelerated computation of combinations of group operations in a finite field is provided by arranging for at least one of the operands to have a relatively small bit length. In a elliptic curve group, verification that a value representative of a point R corresponds the sum of two other points uG and vG is obtained by deriving integers w,z of reduced bit length and that v=w/z. The verification equality R=uG+vQ may then be computed as −zR+(uz mod n)G+wQ=O with z and w of reduced bit length. This is beneficial in digital signature verification where increased verification can be attained.

Abstract: A method of communicating in a secure communication system, comprises the steps of assembling a message at a sender, then determining a frame type, and including an indication of the frame type in a header of the message. The message is then sent to a recipient and the frame type used to perform a policy check.
