In this guide, we’ll dive into the fundamentals of AES encryption, explore its advantages, and discuss how Splashtop integrates AES-256 encryption to ensure secure, reliable remote access for businesses and individuals.
What is the Advanced Encryption Standard (AES)?
AES Definition
The Advanced Encryption Standard (AES) is a widely used encryption protocol designed to protect sensitive data by transforming readable information into a secure, encoded format. AES is a symmetric key encryption method, meaning it uses the same key for both encryption and decryption, ensuring data remains secure during transmission or storage.
What Is AES Used For?
AES is the backbone of data security across many modern applications. This encryption standard is used to safeguard data in wireless communications, cloud storage, databases, mobile applications, and more. With its speed and strong security, AES has become the go-to method for securing data in various industries, from healthcare to finance.
How Does AES Encryption Work?
AES encryption functions by using a symmetric key algorithm, where both encryption and decryption occur with the same key. This process starts with key generation, then moves through multiple encryption rounds where data is substituted, transposed, and transformed through a combination of substitution-permutation networks.
These operations create encrypted data that is difficult for unauthorized users to access. AES relies on block ciphers, which divide data into blocks, applying encryption to each block for consistent security.
3 Types of AES Encryption
AES encryption offers three key lengths—128-bit, 192-bit, and 256-bit—each varying in security strength and use cases:
AES-128 Encryption
This option uses a 128-bit key and is known for its balance between speed and security. AES-128 provides robust protection for general data security needs, including secure file sharing and basic data protection in applications where high speed is essential.
AES-192 Encryption
With a 192-bit key, this version of AES offers a higher security level than AES-128. Although it is slightly slower, AES-192 is often used in industries that require stronger encryption but don’t want the added computational demand of AES-256. It’s suitable for secure communications in government or regulatory settings.
AES-256 Encryption
The most secure version of AES, AES-256 uses a 256-bit key and is virtually immune to brute-force attacks with current technology. While it’s the most computationally intensive, it’s preferred in applications demanding maximum security, such as financial transactions, cloud storage, and data backups. AES-256 is widely used in sectors requiring top-level security, like healthcare and financial services.

Multiple Key Sizes: AES supports key sizes of 128, 192, and 256 bits. These options provide flexibility for different security needs, allowing users to choose a key length based on the desired balance between speed and security.
Block Cipher Method: AES uses a block cipher approach, dividing data into blocks (typically 128 bits) and encrypting each block separately. This structure enhances security by ensuring that each data block is independently secured.
Substitution-Permutation Network: The AES algorithm includes rounds of substitution and permutation, transforming plaintext into ciphertext in a complex way. This design provides strong security by thoroughly mixing data, making it highly resistant to unauthorized access.
Efficient Performance: AES is optimized for both hardware and software, ensuring fast encryption and decryption speeds. This efficiency allows AES to secure data without significantly impacting performance, ideal for real-time applications.
Resistance to Known Attacks: AES is designed to be resilient against known cryptographic attacks, including brute-force, differential, and linear cryptanalysis. This robustness makes it suitable for high-security environments.
Real-World Applications of AES Encryption
AES encryption is widely used across various sectors to ensure data security and privacy. Here are some common real-world applications:
Wireless Security (Wi-Fi): AES is commonly used in Wi-Fi security protocols, such as WPA2 and WPA3, to encrypt data transmitted over wireless networks. This ensures that sensitive information, like passwords and personal data, remains protected from unauthorized access.
Encrypted Browsing (HTTPS): Websites use AES encryption within HTTPS protocols to secure data transmitted between browsers and servers. This encryption helps protect user information, such as login credentials and payment details, from interception by malicious actors.
Mobile Applications: Many mobile apps, especially those dealing with financial transactions or personal data, use AES encryption to secure data on devices and in transit. This includes banking apps, social media platforms, and messaging apps, providing users with peace of mind that their data is protected.
Cloud Storage: AES encryption is essential for securing files stored in cloud environments. Services like Google Drive, Dropbox, and others use AES to ensure that uploaded files remain confidential and protected against unauthorized access.
File and Disk Encryption: Operating systems like Windows and macOS offer AES-based encryption options (such as BitLocker and FileVault) for securing entire hard drives or individual files. This is particularly useful for safeguarding personal or sensitive business information stored on physical devices.

Safeguarding AES Encryption: Key Attacks and Prevention Methods
AES encryption is robust, but like any encryption standard, it faces certain types of attacks. Here’s a look at common AES-targeted attacks and how to prevent them:
Brute-Force Attacks: This attack involves systematically attempting every possible key until the correct one is found. Although brute-force attacks are extremely time-consuming and computationally intense, they become more feasible with weaker or shorter keys.
Differential Cryptanalysis: This technique studies how slight differences in plaintext can affect the resulting ciphertext. By analyzing these differences, attackers aim to deduce key information. AES is resistant to differential cryptanalysis, but understanding it helps ensure encryption practices remain robust.
Side-Channel Attacks: Side-channel attacks exploit indirect information, like power consumption or electromagnetic leaks, rather than targeting the algorithm itself. Attackers use this side information to infer the encryption key. Physical access to the encryption device is usually required, making side-channel attacks more specialized.
How to Prevent AES Encryption Attacks
Use Longer Key Lengths: AES-256, for example, offers much stronger protection than AES-128, making it more resistant to brute-force attacks. Choosing a longer key length increases the time and resources required for an attacker to break the encryption.
Ensure Key Secrecy: Keep encryption keys securely stored and limit access to authorized personnel only. Using key management solutions can help maintain tight control over keys and prevent unauthorized access.
Implement Physical Security Measures: For side-channel attacks, physical security around hardware performing encryption is essential. Secure the environment where encryption takes place to prevent unauthorized access to devices.
Regularly Update and Patch Systems: Encryption implementations in software should be updated regularly. Vulnerabilities in outdated systems can be exploited, so using up-to-date software helps prevent attacks that target weak spots in older implementations.
Avoid Weak or Predictable Keys: Key generation should always use a reliable random number generator to prevent keys from being predictable. Avoid using keys that could be easily guessed or that follow a recognizable pattern.
By understanding and implementing these preventative measures, AES encryption can remain secure against potential attacks, ensuring ongoing data protection.
AES Encryption vs. Other Encryption Standards
AES is a widely adopted encryption standard, but several others are also in use. Here’s a comparison of AES with other popular standards, such as DES and RSA, highlighting the differences in security, speed, and efficiency.
RSA vs. AES
Encryption Type: RSA is an asymmetric encryption standard, meaning it uses a pair of keys (public and private) for encryption and decryption, while AES is a symmetric encryption standard, using the same key for both processes.
Security and Key Length: RSA generally requires longer key lengths (such as 2048 or 4096 bits) to achieve security comparable to AES-128, AES-192, or AES-256. Because of its shorter keys, AES is usually faster and still provides robust security.
Efficiency: AES is more efficient for encrypting large amounts of data, while RSA is commonly used for securing small data transfers, such as establishing secure connections in SSL/TLS handshakes. In most cases, AES is chosen for data encryption due to its speed and lower computational demands.
AES vs. DES
Key Length and Security: DES (Data Encryption Standard) uses a 56-bit key, making it vulnerable to brute-force attacks. AES, on the other hand, supports 128, 192, and 256-bit keys, providing much stronger security.
Algorithm Structure: DES uses a block size of 64 bits, while AES uses 128-bit blocks, which enhances AES’s resistance to certain types of cryptographic attacks.
Efficiency and Modern Usage: AES is far more efficient and secure than DES, which is now considered obsolete due to its shorter key length and vulnerability. AES has effectively replaced DES in most modern applications.
AES-128, AES-192, and AES-256 Differences
