Java Security

Good Day for all

I'm trying to develop a JCE Provider but I've had a problem while getting a Cipher instance. I can instantiate a signature object but when I try getting a Cipher instance I receive the following exception

Exception in thread "main" java.lang.SecurityException: JCE cannot authenticate the provider ProviderTeste
