Abstract
The present disclosure discloses a method and network device for offloading cryptographic functions to support a large number of clients. Specifically, a network device receives a packet corresponding to a client device via an interface, and determines whether a first hardware module that performs cryptographic operations on a per-client basis overflows. If first hardware module overflows, the network device retrieves a cryptographic key for the packet, and sends the received packet with the retrieved cryptographic key to a second hardware module that performs cryptographic operations on a per-packet basis to perform one or more cryptographic operations. If not, the network device sends the packet to the first hardware module to perform the one or more cryptographic operations.
