Techniques of keyless authentication of computing services in distributed computing systems are disclosed herein. One example technique includes upon receiving a command to instantiate a computing service, transmitting a request to an authentication service for an identity assertion token corresponding to an application execution of which instantiates the computing service. The example technique can also include upon receiving the requested identity assertion token, storing the received identity assertion token in the container and modifying an entry of a configuration file in the container that allows the instantiated computing service to access the stored identity assertion token and authenticate to the authentication service using the identity assertion token.

Keyless authentication scheme of computing services

Techniques of dynamic authentication scheme selection in distributed computing systems are disclosed herein. One example technique includes analyzing a received authentication request for an indicator of an authentication scheme that is supported by a computing service submitting the authentication request. The example technique can also include determining whether the authentication scheme associated with the indicator is also supported by the authentication service and in response to determining that the authentication scheme associated with the indicator is also supported by the authentication service, initiating an authentication process with the computing service according to the authentication scheme that is supported by both the computing service and the authentication service. As such, the authentication scheme can be dynamically selected at the authentication service for the received authentication request.

Dynamic authentication scheme selection in computing systems

Techniques of data authentication in a distributed computing system are disclosed herein. One example technique includes receiving a request for performing an operation along with a data package that includes a security token, a first digital signature of the security token generated using an ephemeral private key, and an ephemeral public key with a second digital signature generated using a master private key stored at a secure location. The example technique can also include initially validating the second digital signature using a public key corresponding to the master private key, and upon validating the second digital signature, validating the first digital signature of the security token using the ephemeral public key included in the data package. Upon validating that the first digital signature of the security token, the request can be authenticated, and the requested operation can be performed.
