Abstract

A technology is described for applying authentication on a constrained bandwidth link. The method may determine an amortization factor for authentication to be applied to data blocks sent across the constrained bandwidth link. The amortization factor may be pre-set or received from a user during a communication session. Another operation may be generating truncated authentication codes that are keyed cryptographic checksums for the data blocks. A truncation size of the truncated authentication codes may be defined in part by the amortization factor. The data blocks may be sent across the constrained bandwidth link with the truncated authentication codes to the receiving node.

Abstract

A technology is described for applying security to a message to be sent over a constrained bandwidth link. The method may include identifying a priority portion of the message, using machine learning, that is to be sent with increased security as compared with a remainder of the message. A level of security to be applied to the priority portion of the message may be determined. A security protocol may be applied to the priority portion of the message, as defined in part by the level of security. The data packets may be sent for the message across the constrained bandwidth link to a receiving node.

Abstract

Techniques are described herein for a messaging system to allow publishers that are aware of the identities of their respective subscribers to target content at those subscribers directly. This may be accomplished by allowing users and other targets (e.g., groups) to register their identities at particular computing nodes of a system. Then publishers (e.g., applications) may send out messages targeted at particular identities, and a publishing system may forward messages to appropriate nodes based on which identities are registered at those nodes. Legacy applications that are not able to target particular identities may instead connect to application adapters that are configured to learn which identities should be targeted by each application. In addition, anonymized identities may be used for application messages that need to cross between domains having differing security levels.

Abstract

Techniques for automated system requirements analysis are disclosed. A system requirements analysis (SRA) service generates a system model that includes system requirements, at least by performing natural-language processing on a natural-language representation of the system requirements. Based at least on the system model, the SRA service performs an analysis of the system requirements against codified system requirements rules. The SRA service determines, based at least on the analysis of the system requirements against the codified system requirements rules, that the system requirements include a violation of a system requirements rule. The SRA service generates a report that identifies at least (a) the violation of the system requirements rule and (b) a suggested action to remediate the violation of the system requirements rule.

Abstract

An adaptive modulation, coding and spreading (AMCS) transmitter is configured to map modulation symbols to a plurality of OFDM subcarriers to generate symbol-modulated subcarriers. For AMCS, some of the modulation symbols may be mapped to individual subcarriers (e.g., similar to conventional OFDM) and one or more of the modulation symbols may be mapped to (i.e., spread across) more than one of the subcarriers (i.e., unlike conventional OFDM) based on a spreading ratio. An IFFT may be performed on the symbol-modulated subcarriers prior to transmission. AMCS allows for adaptation to lower capacity and/or frequency-selective channels by optionally spreading existing modulations over multiple carriers and/or time slots. AMCS expands the catalog for possible modulations/codings by splitting a symbol across multiple carriers and/or time slots. AMCS is particularly useful when channel conditions are highly frequency-dependent or uniformly low capacity.

Abstract

A machine accesses a preexisting set of natural language text documents in multiple natural languages. Each natural language text document in at least a portion of the preexisting set is associated with an event. The machine trains, using the preexisting set of natural language text documents and the associated events, an event encoder to learn associations between texts and event annotations. The event encoder leverages a parser in each of the two or more natural languages. The machine generates, using the event encoder, new event annotations for texts. The machine trains, using the preexisting set of natural language text documents and the new event annotations for the texts generated by the event encoder, an event extraction engine to extract events from natural language texts in the two or more natural languages. The event extraction engine leverages the parser in each of the two or more natural languages.
