Abstract
A first IoT device includes a memory, a transceiver, bloom filter evaluation, false positive comparison and control modules. The memory stores: a bloom filter set including an array of bits representing entries in a certificate revocation list; and a false positive set including a list of certificate entries falsely identified as being revoked. The transceiver receives from a second IoT device a message including a certificate. The bloom filter evaluation module receives the bloom filter set from a back office station and determines whether an identifier associated with the certificate is in the bloom filter set. The false positive comparison module receives the false positive set from the back office station and determines whether the identifier is in the false positive set. The control module permits communication between the first and second IoT devices based on whether the identifier is in the bloom filter and false positive sets.
