Abstract
Preventing replay attacks on servers. At least one Bloom filter may be set up in a server for tracking requests received from clients. Identifying data may be generated for each request. The identifying data may be checked against the Bloom filter array. If a match is found, the message may be a replay and may be rejected. If a match is not found, the request identifying data may be added to the Bloom filter and the request may be processed.
