Secure transmission of tokens using private key fragments

A system comprising:

• one or more processors;
• and
• a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to:
• receive an encrypted token generated using a public key of an asymmetric key pair;
• receive a first partially decrypted token generated by applying a first private key fragment of a private key of the asymmetric key pair to the encrypted token;
• apply a second private key fragment of the private key to the encrypted token to generate a second partially decrypted token;
• apply a third private key fragment of the private key to the encrypted token to generate a third partially decrypted token;
• and
• combine the first partially decrypted token, the second partially decrypted token and the third partially decrypted token to generate a decrypted token.

A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions to:

• receive an encrypted token generated using a public key of an asymmetric key pair;
• receive a first partially decrypted token generated by applying a first private key fragment of a private key of the asymmetric key pair to the encrypted token;
• apply a second private key fragment of the private key to the encrypted token to generate a second partially decrypted token;
• apply a third private key fragment of the private key to the encrypted token to generate a third partially decrypted token;
• and
• combine the first partially decrypted token, the second partially decrypted token and the third partially decrypted token to generate a decrypted token.
