TECHNIQUES FOR SECURE DATA EXCHANGE

摘要

Disclosed are various embodiments for securely sending and receiving data between one or more clients. A ciphertext key suitable for use by a first encryption algorithm is generated. Plaintext data is encrypted according to the first encryption algorithm using the first encryption key. The ciphertext key is then encrypted using a second encryption algorithm configured with a recipient key to generate a recipient wrapper. The ciphertext data and the recipient wrapper are then transmitted to a remote computing device via a network.

主权项

1. A system, comprising:
a computing device having a processor; and a cryptographic application executable in the computing device, the cryptographic application comprising:
logic that generates a ciphertext key, the ciphertext key being suitable for use by a first encryption algorithm;logic that encrypts plaintext data using the first encryption algorithm configured with the ciphertext key, wherein the first encryption algorithm operating upon the plaintext data produces ciphertext data;logic that encrypts the ciphertext key using a second encryption algorithm configured with a recipient key, wherein the second encryption algorithm operating upon the ciphertext key produces a recipient wrapper that comprises the encrypted ciphertext key; andlogic that transmits the ciphertext data and the recipient wrapper to at least one remote computing device accessible via a network.
