  • breath-of-life packet — (XEROX PARC) An Ethernet packet that contains bootstrap code, periodically sent out from a working computer to infuse the "breath of life" into any computer on the network that has crashed.

The notional "kiss-of-death packet", with a function complementary to that of a breath-of-life packet, is recommended for dealing with hosts that consume too many network resources. Though "kiss-of-death packet" is usually used in jest, there is at least one documented instance of an Internet subnet with limited address-table slots in a gateway computer in which such packets were routinely used to compete for slots, rather like Christmas shoppers competing for scarce parking spaces.

  • certificate authority — (cryptography, body)   (CA or "Trusted Third Party") An entity (typically a company) that issues digital certificates to other entities (organisations or individuals) to allow them to prove their identity to others. A Certificate Authority might be an external company such as VeriSign that offers digital certificate services or they might be an internal organisation such as a corporate MIS department. The Certificate Authority's chief function is to verify the identity of entities and issue digital certificates attesting to that identity. The process uses public key cryptography to create a "network of trust". If I want to prove my identity to you, I ask a CA (who you trust to have verified my identity) to encrypt a hash of my signed key with their private key. Then you can use the CA's public key to decrypt the hash and compare it with a hash you calculate yourself. Hashes are used to decrease the amount of data that needs to be transmitted. The hash function must be cryptographically strong, e.g. MD5.
