AUTHENTICATING ACCESS TO AN INSTANCE

A system, method, and non-transitory computer-readable storage medium for authenticating access to an instance have been disclosed. The system comprises a processor and a memory that includes instructions executable by the processor to cause the system to receive an access request to the instance from a client device and to send an encryption request of information to a security device. The information includes an expiration time and the security device encrypts the information using a private key that is secured in the security device. The memory includes further instructions executable by the processor to cause the system to receive the encrypted information from the security device and to send the encrypted information to the client device. The encrypted information is decryptable by the instance using a public key associated with the private key in response to the client device providing the encrypted information to the instance.
