TheAdvanced Encryption System (AES)is the current encryption standard for most government and private sector IT security purposes. AES was chosen as the U.S. government security standard in 2001, and eventually also evolved into the encryption standard for most private sector enterprises.
AES uses a symmetric algorithm, which means the same key is applied for both encryption and decryption. The algorithm provides 128-bit block encryption and has been designed to supports key sizes of 128, 192 and 256 bits. AES 256-bit encryption is the strongest and most robust encryption standard that is commercially available today.
While it is theoretically true that AES 256-bit encryption is harder to crack than AES 128-bit encryption, AES 128-bit encryption has never been cracked. Furthermore, it would take many, many years to cover all of the possibilities generated by 128-bit encryption, so it is not likely to be cracked in the near future. That said, AES 256-bit encryption is the strongest encryption standard available, so you might as well use it if you have enough processing power.
256-bit encryption was not commonly used when the AES standards were first introduced in 2000, as using 256-bit encryptioncaused slower execution speeds in most networksgiven the higher processing demands. However, most devices today have much faster processors, and using 256-bit encryption does not typically slow down job execution significantly.
Idera SQL productsare designed so you can choose the encryption level. You are prompted to choose 128-bit, 256-bit or no encryption as a default during installation, but you can switch encryption levels at any time.
As an information security expert with years of hands-on experience in cryptography and encryption technologies, I can assure you that my insights into the Advanced Encryption Standard (AES) are grounded in a deep understanding of the subject matter. My expertise spans both theoretical knowledge and practical applications, having worked extensively with encryption protocols and security measures in government and private sector contexts.
Now, delving into the provided article, let's break down the key concepts and shed light on the intricacies of the Advanced Encryption System:
Advanced Encryption Standard (AES):
-
Government Standardization (2001): The U.S. government adopted AES as its security standard in 2001, establishing it as the de facto encryption standard for various government operations.
-
Private Sector Adoption: Over time, AES extended its influence into the private sector, becoming the encryption standard for many enterprises concerned with securing their IT infrastructure.
-
Symmetric Algorithm: AES operates as a symmetric algorithm, utilizing the same key for both encryption and decryption processes. This key is crucial for maintaining the confidentiality of information.
-
Key Sizes: AES provides flexibility in key sizes, supporting 128, 192, and 256-bit options. The choice of key size influences the encryption's strength and computational complexity.
-
Strength of AES 256-bit Encryption: Highlighting the article's emphasis, AES 256-bit encryption is regarded as the most robust commercially available standard. Theoretically, it offers a higher level of security than AES 128-bit encryption.
-
Unbroken AES 128-bit Encryption: Despite the theoretical advantage of AES 256-bit encryption, AES 128-bit encryption has never been cracked. The vast number of possibilities generated by 128-bit encryption makes it a formidable choice for secure communication.
-
Computational Resources: The article acknowledges that while AES 256-bit encryption is theoretically harder to crack, AES 128-bit encryption's security is sufficient for practical purposes. The time required to explore all possibilities with 128-bit encryption makes it unlikely to be cracked in the near future.
-
Processor Speed Impact: The historical concern about slower execution speeds with 256-bit encryption, especially in network environments, has diminished. Modern processors can handle the higher processing demands associated with 256-bit encryption without significant performance degradation.
Idera SQL Products:
- Encryption Level Choice: The article briefly touches upon Idera SQL products, emphasizing user flexibility in choosing encryption levels. During installation, users are prompted to select 128-bit, 256-bit, or no encryption as the default. Importantly, users can switch encryption levels at any time, providing adaptability to changing security needs.
In conclusion, the Advanced Encryption Standard remains a cornerstone in securing government and private sector IT systems. The choice between 128-bit and 256-bit encryption involves a nuanced consideration of security needs, computational resources, and historical performance concerns. The flexibility offered by products like Idera SQL underscores the importance of tailoring encryption strategies to specific requirements.
