Abstract

The application discloses a method of maintaining a database of trusted public keys in a plurality of computer devices. Preferably, the keys are stored in a memory 102 of said device 101. The keys must be suitable for the purpose of eliminating the need to scan trusted files for malware at the computer devices (e.g. see S8, fig. 2). In the method, public keys are identified at a network based service, preferably a certificate authority or CA. The keys belong to a public key infrastructure or PKI architecture and are used in the digital signing of electronic files. The keys, which the method verifies as belonging to a trusted source, are sent securely to the devices.
