When comparing DeepSeek and QodoGen, there is limited information available about QodoGen's encryption methods. However, DeepSeek's encryption practices can be analyzed based on available data.
DeepSeek, in its model training phase, employs robust encryption frameworks to secure sensitive data. It typically uses industry-standard encryption protocols like AES (Advanced Encryption Standard) for encrypting data at rest and TLS (Transport Layer Security) for data transmission[1]. Additionally, DeepSeek can utilize homomorphic encryption, which allows computations on encrypted data without decryption, enhancing privacy and security[1].
However, DeepSeek's mobile apps have faced criticism for using insecure encryption methods. They employ the deprecated 3DES algorithm and have hardcoded encryption keys, which pose significant security risks[3][4][7]. Furthermore, the apps disable App Transport Security (ATS) on iOS, leading to unencrypted data transmission over the internet[3][11].
If QodoGen uses standard encryption methods like AES and TLS without the vulnerabilities found in DeepSeek's mobile apps, it would likely offer more secure data handling practices compared to DeepSeek's current mobile app implementation. Unique encryption methods used by DeepSeek, such as homomorphic encryption for model training, are not mentioned in the context of QodoGen, but this does not necessarily imply that QodoGen lacks robust encryption methods.
In summary, while DeepSeek's model training uses advanced encryption techniques like homomorphic encryption, its mobile apps have significant security flaws. Without specific information on QodoGen's encryption methods, it is difficult to definitively state whether QodoGen lacks any unique encryption methods used by DeepSeek. However, if QodoGen adheres to modern encryption standards without the vulnerabilities present in DeepSeek's apps, it would likely provide more secure data protection.
