Abstract
Methods, apparatuses, and articles for receiving, by a server, a plurality of identifiers associated with a client device are described herein. The server may also encrypt a plurality of encoding values associated with the plurality of identifiers using a first key of a key pair of the server, and generate a token uniquely identifying the client device, a body of the token including the encrypted plurality of encoding values. In other embodiments, the server may receive a token along with the plurality of identifiers. In such embodiments, the server may further verify the validity of the received token, including attempting to decrypt a body of the received token with a key associated with a second server, the second server having generated the received token, and, if decryption succeeds, comparing ones of the plurality of identifiers with second identifiers found in the decrypted body to check for inconsistencies.
