    摘要: An electronic device for storing data content by storing at least a portion of the data content in a rewritable memory device by storing an n bit count value associated with the status of the data content in a one time programmable memory. The n bit count value is written to the secure memory device along with the corresponding data content. Then the n bit count value is incremented and stored in the one time programmable memory each time there is a modification of the data content in the rewritable memory device. The number of bits of the one time programmable memory may correspond to the number of potential modifications of the stored data content.

    摘要: A composite customer ID (CCID) is stored in the OTP memory of integrated circuit chipsets used by a number of different customers. The CCID includes individual customer IDs (CIDs) at defined index positions, each corresponding to a different customer. Each chipset allows or disallows software booting, based reading a certificate index value from a given customer's certificate, reading an OTP CID from OTP, as pointed to the by certificate index value, and evaluating the OTP CID with a certificate CID read from the certificate. Thus, while CCID carries information for a plurality of customers, each customer's certificate points only to that customer's OTP CID, which can be changed to revoke that customer's certificate without revoking the other customers' certificates. The CCID also may include a version number, where the chipsets allow or disallow software booting based on evaluating the certificate version number in view of the CCID version number.

    摘要: A method of pre-authentication of a first entity (10) by a second entity (1) communicating with each other via a wireless connection. The second entity (1) sends (23′) a challenge value (c). If the first entity (10) receives (23) a challenge value (c′), it applies to the received challenge value a predefined transformation (g) known to the second entity to obtain a first transformed value (r) and then sends (24) the first transformed value (r) obtained. If the second entity receives (24′) a transformed value (r′), it compares (25′) the received transformed value to a second transformed value (r″) obtained by applying the predefined transformation (g) to the challenge value sent and considers the pre-authentication to have succeeded if the result of comparing the second transformed value obtained and the transformed value received is below a predefined threshold (m).
