Abstract: A system for providing security services to a mobile device where the mobile device is in communication with a public network through a first network path that is subject to interference by a third party. The system includes a security server and a private network. The security server is operative to communicate with the mobile device through the private network. The security server is also operative to communicate with the public network through a second network path that is less susceptible to the interference by the third party than is the first network path. The security server communicates with the public network through the second network path to provide security services to the mobile device that are delivered over the private network.

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 translation: 公开了用于创建自签名隐式证书的系统和方法。 在一个实施例中，使用与ECQV协议中使用的转换类似的性质的变换来生成和操作自签名隐式证书。 在这样的系统中，根CA或其他计算设备避免必须通过代替生成自签名隐式证书来生成显式的自签名证书。

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: Methods, systems, and computer programs for performing key agreement operations in a communication system are described. In some aspects, a wireless network operator receives a mobile device identifier and accesses a secret key associated with the mobile device. A message authentication code function is evaluated based on the secret key to produce an output value. A session key and a challenge value are obtained based on the output value. In some aspects, a mobile device accesses a secret key in response to receiving the challenge value from the wireless network operator. A message authentication code function is evaluated based on the secret key to produce an output value. A response value and a session key are obtained based on the output value. The response value is transmitted to the wireless network operator.

Abstract: An asset management system is provided, which includes a hardware module operating as an asset control core. The asset control core generally includes a small hardware core embedded in a target system on chip that establishes a hardware-based point of trust on the silicon die. The asset control core can be used as a root of trust on a consumer device by having features that make it difficult to tamper with. The asset control core is able to generate a unique identifier for one device and participate in the tracking and provisioning of the device through a secure communication channel with an appliance. The appliance generally includes a secure module that caches and distributes provisioning data to one of many agents that connect to the asset control core, e.g. on a manufacturing line or in an after-market programming session.

Abstract: During generation of a signature on a message to create a signed message, a signer determines one of the signature components such that particular information can be extracted from the signature component. The particular information may be related to one or more of the signer and the message to be signed. After receiving a signed message purported to be signed by the signer, a verifier can extract the particular information from the signature component.
Abstract translation: 在生成消息的签名以产生签名消息时，签名者确定签名组件中的一个，从而可以从签名组件提取特定信息。 特定信息可以与签名者和要签名的消息中的一个或多个有关。 在收到签名者签名的签名信息后，验证者可以从签名组件中提取特定信息。
