Methods and systems for facilitating a client-server communication using cyclic tokens

Abstract:

Embodiments provides a method for facilitating a client-server communication using cyclic tokens. The method includes receiving a request for token generation from a client device, generating a token in response to the request for token generation, and sending the token and a number of sub-tokens to be formed from the token to client device. The method includes establishing a cyclic token by token server for client device, where establishing includes generating a plurality of sub-tokens from the token based on the number of sub-tokens. Method further includes sending the plurality of sub-tokens of token to client device in an order defined by a sequence, and recording the plurality of sub-tokens in an order defined by the sequence as cyclic token. The method further includes facilitating validation of cyclic token upon receipt of sub-tokens in order of sequence as part of token validation request from an application server for client device.
