Abstract
A server and method for providing a content selection is provided. The server receives content targeting parameters and obtains content items from at least one content site based on the content targeting parameters. The server can further identify content descriptors for the content items and generate a first content cluster from a subset of the content items based on the content descriptors. The server can further generate a second content cluster from a second subset of the content items based on the content descriptors and rank the first and the second content clusters in an order of usefulness. The ranking of the content clusters can be based on at least one of an importance of content, a recentness of the content items and a size of the content cluster.

A method of receiving an enhanced public key by a public key server for securing system communications, the public key server having a processor operably connected to memory and a communications interface, the method comprising:
- maintaining in the memory a current enhanced public key;
- transmitting, through the communications interface, the current enhanced public key associated with a client account to the client account;
- receiving, through the communications interface, a decrypted first portion of the current enhanced public key for verifying the client account along with a new enhanced public key associated with the client account;
- extracting, by the processor, from the current enhanced public key and decrypting using the received decrypted first portion of the current enhanced public key for verifying the client account, a second portion of the current enhanced public key for verifying the client account;
- and
- buffering, in the memory, the new enhanced public key when the received decrypted first portion of the current enhanced public key for verifying the client account matches the decrypted second portion of the current enhanced public key for verifying a client account.

A public key server for securing system communications, the public key server comprising:
- memory;
- a communications interface;
- a processor operably connected to the memory and the communications interface, the processor configured to:
- maintain in memory a current enhanced public key;
- transmit, through the communications interface, the current enhanced public key associated with a client acount to the client account;
- receive, through the communications interface, a decrypted first portion of the current enhanced public key for verifying the client account along with a new enhanced public key associated the client account;
- extract a second portion of the current enhanced public key from the current enhanced public key, and decrypt the second portion of the current enhanced public key using the received decrypted first portion of the current enhanced public key for verifying the client account;
- and
- buffer, in the memory, the new enhanced public key when the received decrypted first portion of the current enhanced public key for verifying the client account matches the decrypted second portion of the current enhanced public key for verifying a client account.
