Guarding against cross-site request forgery (CSRF) attacks
Cross-Site Request Forgery attacks are mitigated by a CSRF mechanism executing at a computing entity. The CSRF mechanism is operative to analyze information associated with an HTTP request for a resource. The HTTP request typically originates as an HTTP redirect from another computing entity, such as an enterprise Web portal. Depending on the nature of the information associated with the HTTP request, the HTTP request may be rejected because the CSRF mechanism determines that the request is or is likely associated with a CSRF attack. To facilitate this determination, the approach leverages a new type of “referer” attribute, a trustedReferer, which indicates that the request originates from a server that has previously established a trust relationship with the site at which the CSRF mechanism executes. The trustedReferer attribute typically is set by the redirecting entity, and in an HTTP request header field dedicated for that attribute. |

Open loop oscillator time-to-digital conversion
A time-to-digital converter (TDC) detects a timing relationship between signals representing two temporal events. Several samples are acquired over a certain time period for each event, and the signals related to the different events are digitized or quantized either by separate TDCs or by a single TDC in a time-sequential manner. The quantized results are then processed, for example added to/subtracted from one another, and used to determine the phase or time difference between the two events. When information being quantized is quasi-static over time periods where the measurement is performed, the instantaneous or “one shot” accuracy of a TDC need not be as good as or better than the desired time resolution. Digitally processing the signals and averaging the results moves an otherwise difficult analog quantizer problem to the digital domain where savings in power and chip area can be easily achieved without sacrificing accuracy. |
