    Abstract: In order to reduce latency of elliptical curve digital signature generation a portion of the digital signature is pre-calculated before receipt of the message hash using an unmodified ECDSA computing engine. After the message hash is received, the digital signature is completed without using the ECDSA computing engine. Applications include generating digital signatures for the safety messages in Intelligent Transport Systems.

    Abstract: In one example, a circuit includes a secure chip storing one of an enclave of key values linked to an update code; a memory to store an updatable data set including the update value which corresponds to and is revised with the update code; and a logic circuit. The logic circuit is to: provide a key value, based to a revision to the update code, from among the enclave of key values, generate an authentication tag as a function of the provided key value, use the authentication tag to verify that the updatable data set is valid and up to date before using the updatable data set in an application specified for the updatable data set, and update the data set by storing a replacement updatable data set in the memory circuit and including, in the replacement updatable data set, a revised update value which corresponds to a revised update code that is used to provide another key value from among the enclave of key values.
