![]() Message-specific keys are passed through a key derivation function that binds the key exchange to a recipient device. This ensures that only intended recipients have the message-specific AES key to decrypt the message. The message-specific AES key is exchanged with recipients via a Diffie-Hellman elliptic curve key exchange (EDCH521) mechanism. The message content (text, files, audio, or video) is encrypted on the sending device (your iPhone, for example) using the message-specific AES key. It means that the system provides authenticity and confidentiality: no unauthorized party can inject a message into the system, and no unintended party can access or understand the communications without being given them by one of the correspondents.Įach message gets a unique AES encryption key and a unique ECDH public key to negotiate the key exchange with other recipients. Wickr provides secure communication between two or more correspondents. The information retained is stored on the servers you choose and stays entirely under your control. The flexible administrative controls make it easy for your Wickr administrator to manage the communication channels and retain information to meet regulatory requirements when required. Unlike many enterprise communication tools, Wickr uses end-to-end encryption mechanisms to ensure your messages, files, voice, or video calls are solely accessible to their intended recipients. I am excited to announce the availability of AWS Wickr, an enterprise communications service with end-to-end encryption, that allows businesses and public sector organizations to communicate more securely, enabling customers to meet auditing and regulatory requirements like e-discovery, legal hold, and FOIA requests. Update Janu: I removed the reference to AWS CDK.
