Secure client-server communication
A secure client-server connection method compatible with RESTful (REpresentational State Transfer) APIs (Application Programming Interface) that is resistant to cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks. The server generates a token for the client and a random value which it pairs with the token. The random value is hashed. The hash value is transmitted to the client contained in the token and the random value is transmitted to the client contained in an HTTPOnly cookie. Even if an attacker steals the token and/or the hash, security is maintained, since the server verifies communications from the client by validating the token on the basis of its hash value. Validation is performed by the server hashing the random value contained in the HTTPOnly cookie paired with the token to obtain a further hash value, and checking that this further hash value matches the token's hash value. |

Techniques of authenticating a new user involve classifying a new user as a member of a group based on the new user's current activity. Along these lines, when a new user enrolls in an authentication system, the authentication system places the new user in a group of new users that have not made any requests and are assumed to be high risks of making fraudulent requests. Once the new user makes a request to access a resource, the authentication system classifies the new user as a member of another group according to authentication factors describing activities surrounding the request. |

Optimizing fabric path forwarding for virtual nodes within an electronic device
The techniques describe directly forwarding a packet from an ingress packet forwarding engine to a particular destination packet forwarding engine (PFE) when internal packet load balancing may otherwise result in an increased number of fabric hops.

Current-starving in tunable-length delay (TLD) circuits in adaptive clock distribution (ACD) systems for compensating voltage droops in clocked integrated circuits (ICs) is disclosed. Voltage droops slow propagation of signals in clocked circuits. However, clock delay circuits in a TLD circuit increase a clock period by increasing a clock delay in response to a voltage droop.

If the voltage droop at the TLD circuit is smaller than at the clocked circuit, then the clock period isn't stretched enough to compensate the slowed clocked circuit. A current-starved TLD circuit starves the clock delay circuits of current in response to a voltage droop indication, which further increases the clock signal delay, and further stretches the clock period to overcome a larger voltage droop in clocked circuits in other areas of the IC. |
