摘要： Improved key management techniques are disclosed for temporal access control of one or more services in a computer network. For example, a method for providing access control in a client-server system includes the following steps. A client obtains an authorization key for a time interval. A server derives an encryption key corresponding to a given time and uses the encryption key to encrypt a message. The client derives a decryption key corresponding to the given time and decrypts the message.

摘要： Improved load balancing techniques are disclosed. For example, in one illustrative aspect of the invention, a method of satisfying requests in a system comprised of a plurality of servers comprises the following steps. At least one load balancer is provided for routing requests to the plurality of servers. At the at least one load balancer, a request sent from a client is obtained. At the at least one load balancer, the request is examined. Costs of satisfying the request by at least two of the plurality of servers are estimated. The estimation is based on at least one of a number and a cost of at least one remote access for satisfying the request. The request is routed to a server of the plurality of servers with a low estimated cost of satisfying the request.
