Systems and methods for providing data security services
View Patent ↗Embodiments described herein provide enhanced computer- and network-based systems and methods for providing data security with respect to computing services, such as a digital transaction service (DTS). Example embodiments further provide a discovery service that enables nodes that are included in, or otherwise communicatively coupled to, the DTS to actively or passively “discover” roles and keys associated with the nodes. These node roles are associated with the various services provided by the DTS. A security module provides at least a portion of the security services.
1. A method for providing security services that are associated with an online service, the online service includes a digital transaction service that is at least partially provided by a computing cluster that includes a first node, the method comprising employing a security module that is distinct from the computing cluster to:
generate a session key, wherein the session key is a symmetric session key;
associate the session key with the first node and a second node;
receive payload data originating from the first node;
symmetrically encrypt the received payload data based on the session key; and
provide a first message to the second node, wherein the first message includes the encrypted payload data.
2. The method system of claim 1 , the method further comprising employing the security module to:
receive a second key that is associated with the second node;
encrypt the session key based on the received second key that is associated with the second node; and
provide the encrypted session key to a key manager that is associated with the second node.
3. The method of claim 1 , wherein the first message is transmitted by the second node to the first node, and subsequently the first node transmits the first message to the security module.
4. The method of claim 1 , wherein the method further comprises employing the security module to:
receive additional payload data originating from the second node, wherein the received additional payload data is symmetrically encrypted;
symmetrically decrypting the additional payload data based on the session key; and
provide a second message to the first node, wherein the second message includes the decrypted additional payload data.
5. The method of claim 1 , the method further comprising employing a key manager included in the security module to:
store the session key;
actively safeguard the stored session key; and
in response to a request from the online service, delete the stored key.
6. A non-transitory computer-readable medium including instructions that, when executed by a computing system having a computing cluster, perform a method that enables a security module that is distinct from the computing cluster to provide security services to a plurality of nodes that are distinct from the computing system executing the instructions, wherein the plurality of nodes includes a first node that is included in a digital transaction service, the method comprising:
generating a session key;
associating the session key with a secure data exchange session between the first node and a second node;
receiving payload data originating from the first node;
encrypting the received payload data based on the session key; and
providing a first message to the second node, wherein the first message includes the encrypted payload data.
7. The computer-readable medium of claim 6 , the method further comprising:
encrypting the session key based on a key associated with the second node; and
providing the encrypted session key to a key manager associated with the second node.
8. The computer-readable medium of claim 6 , wherein the session key is a symmetric session key associated with a persistently secure data exchange session between the first and the second nodes.
9. The computer-readable medium of claim 6 , wherein the second node is distinct from the plurality of nodes.
