Authentication scheme in a virtual private network

A device, comprising:

• a memory;
• and
• a processor communicatively coupled to the memory, the memory and the processor being configured to:
• configure a first server to determine an encrypted authentication packet, wherein to configure the first server to determine the encrypted authentication packet, the memory and the processor are configured to,
• configure the first server to determine a crypted code field to indicate a type associated with the encryption authentication packet and that at least a portion of the encryption authentication packet is encrypted, and
• configure the first server to determine a crypted payload based at least in part on encrypting one or more fields of an initial authentication packet;
• and
• configure the first server to transmit, to a second server, the encrypted authentication packet to enable the first server and the second server to conduct an authentication process.

A non-transitory computer-readable medium configured to store instructions, which when executed by a processor associated with a device, configure the processor to:

• configure a first server to determine an encrypted authentication packet, wherein to configure the first server to determine the encrypted authentication packet, the processor is configured to,
• configure the first server to determine a crypted code field to indicate a type associated with the encryption authentication packet and that at least a portion of the encryption authentication packet is encrypted, and
• configure the first server to determine a crypted payload based at least in part on encrypting one or more fields of an initial authentication packet;
• and
• configure the first server to transmit, to a second server, the encrypted authentication packet to enable the first server and the second server to conduct an authentication process.
