Whisper MSG X Volare AMA — 2
Hello! Great fans of Whisper MSG!
We are pleased to have another exciting opportunity to interact closely with our community participants.
What is Whisper MSG?
l Whisper MSG is the ultimate secure messenger app that successfully applies blockchain technology to a consumer-focused product.
l Under its global slogan, “Your privacy is our priority”, Whisper MSG is the most secured blockchain-based communication service to date, complete with a built-in digital wallet feature to effectively transfer and manage various digital assets right on the messenger.
l Whisper guarantees anonymity for messages and other information exchanges by not storing information on a central server, and automatically destroys and deletes messages through a self-destruct feature.

What are the technological advantages of Whisper MSG?
The technical advantages of Whisper are as follows:
1) Message encryption
There are three main types of encryption methods.
First, one-way encryption is a method in which decryption is impossible when plaintext is encrypted, and an example thereof is hash. Usually, this method is often used for data source verification.
Secondly, in symmetric key encryption method, the plaintext is encrypted with a specific symmetric key, and the resulting ciphertext can also be decrypted with the same symmetric key. The advantage of this method is fast encryption processing time. However, when the symmetric key is delivered to the recipient, there is a possibility that the symmetric key can be hijacked by a middle attack.
Lastly, the asymmetric key encryption method, which can be divided into two types.
a). Plaintext -> Encrypt with private key -> Ciphertext -> Decrypt with public key -> Plaintext
Method a). is used as an electronic signature. This is because, if you sign with your private key, you can determine the authenticity of this digital signature by decrypting it with your public key.
b). Plaintext -> encryption with public key -> ciphertext -> decryption with private key -> plaintext
When designing Whisper, we have focused on concealing information while transferring the information on an open ledger, hence used the Method b).
Whisper MSG exchanges public keys and addresses with each other when adding friends. When the message content is encrypted with the sender’s private key and the receiver’s public key, it can only be decrypted with the receiver’s private key and the sender’s public key. This means that no one except the recipient can decrypt the message, assuming that the recipient’s private key is not disclosed.
In addition, the asymmetric key encryption method has the disadvantage of being slow because the key is long. To address these shortcomings, we have adopted an elliptic curve algorithm, which is an algorithm that provides the same level of security even with a shorter key compared to other asymmetric key encryption algorithms.
2) Mnemonic codes
Whisper provides Mnemonic codes to help users to easily remember their important private keys.
The origin of the word ‘Mnemonic’ is ‘to help make something easier to remember, or to be easily remembered’.
In other words, the mnemonic code is an algorithm that converts the user’s 64-digit private key into an array of 24 words to make it easier to remember. The method of generating the mnemonic code is as follows.
① Create a cryptographically random 256-bit sequence S1.
② Among the SHA-256 hash values of S, the first 8 bits are used as the checksum.
③ Add S and the checksum created in step 2 to make S2 with 264 bits.
④ S2 is cut into 11 bits and each 11 bits is replaced with a predefined word from a set of 2048 predefined words.
⑤ Generate a mnemonic code while maintaining order from a sequence of words.
The 24 ordered word list generated as the above replaces the 64-digit private key. This technology enhances user convenience by helping users to resume the service through the arrangement of words even when they forget their private key.
3) Smart contract scalability
The smart contracts used in Whisper were created according to certain intended functions. For example, smart contracts were written to function with information security as the prioritized objective.
SendMSG
“SendMSG” is a message transmission smart contract that sends an encrypted message with the recipient’s status.
ReadMSG
“ReadMSG” is a message deletion smart contract that deletes messages in the user’s status.

Is Whisper MSG safe?
Since Whisper does not have any information that can be specified in all user flows, it is impossible to identify users and leak related information.
In Whisper, the messages sent from the sender are deleted as soon as the recipient receives and confirm the messages. Therefore, there’s no message history left for the users to check later.

What is Whisper MSG wallet?
Whisper Wallet allows management of various digital assets in one place and enables remittance between users. Users can exchange digital assets using Whisper Wallet that utilize Equilibrium engine technology. And as the Volare network expands, more gaming-related Dapps will be added to the network, thereby more digital assets can be managed through Wallet.

What is the objective of Whisper MSG?
Currently, Whisper offers a secure messenger function, as well as a digital wallet function.
In the short-term, Whisper intends to offer these functions in better user-friendly interface, all in very secured environment.
In the future, we expect to see numerous Dapps joining the network to be connected through Whisper, while leaving personal information management and security to the users themselves.
