With the proliferation of the internet, the issue of image tampering has escalated, necessitating robust image encryption schemes. Despite the multitude of proposed image encryption algorithms, challenges such as slow computational speed, weak security, and suboptimal visibility persist. This study addresses these challenges by introducing a high-performance encryption algorithm tailored for dynamic images—QEDI (Quick Encryption Algorithm for Dynamic Images). QEDI leverages elliptic curve-based asymmetric encryption algorithms and hash algorithms. The process involves using a hash algorithm to calculate the hash of the dynamic image slated for encryption, employing the elliptic curve algorithm to generate public and private keys, and utilizing the asymmetric encryption algorithm to process the image hash, resulting in a signature ciphertext. This ciphertext is embedded into the dynamic image, completing the encryption process. To enhance the execution speed without compromising the image quality and visibility, the bit depth of the dynamic image is reduced before hash calculation, and custom information fields are encapsulated to embed the signature ciphertext into the dynamic image. Experimental evaluations, conducted within a dynamic image generation system, encompassed assessments of security, encryption algorithm execution time, and image quality. The results indicate that utilizing QEDI for dynamic image encryption yields better security compared to EDI (Encryption Algorithm for Dynamic Images). QEDI exhibits minimal impact on image quality, with a noteworthy 69.77% reduction in execution time compared to EDI. Furthermore, when compared to existing algorithms employing image conversion for encryption, QEDI-encrypted images demonstrate enhanced visibility, better image quality, and expedited encryption speed.

“…However, the problem of image encryption is beyond the application of established and well-known encryption algorithms. This is primarily due to the constraints imposed by the data structure and the application requirements, such as format compliance [3], real-time performance [4], complexity [5], compression efficiency [6], perceptibility [7] and the security level [8]. To address these concerns, significant attempts have been made to develop robust encryption schemes for the image data [9]- [11].…”

Permutation is a commonly used primitive in multimedia (image/video) encryption schemes, and many permutationonly algorithms have been proposed in recent years for protection of multimedia data. In permutation-only image ciphers, the entries of the image matrix are scrambled using a permutation mapping matrix which is built by a pseudo-random number generator (PRNG). The literature on the cryptanalysis of image ciphers indicates that permutation-only image ciphers are insecure against ciphertext-only attacks and/or known/chosenplaintext attacks. However, previous studies have not been able to ensure the correct retrieval of the complete plaintext elements. In this paper, we re-visited the previous works on cryptanalysis of permutation-only image encryption schemes and made the cryptanalysis work on chosen-plaintext attacks complete and more efficient. We proved that in all permutation-only image ciphers, regardless of the cipher structure, the correct permutation mapping is recovered completely by a chosen-plaintext attack. To the best of our knowledge, for the first time, this paper gives a chosen-plaintext attack that completely determines the correct plaintext elements using a deterministic method. When the plain-images are of size M × N and with L different color intensities, the number n of required chosen plain-images to break the permutation-only image encryption algorithm is n = log L (M N). The complexity of the proposed attack is O (n• M N) which indicates its feasibility in a polynomial amount of computation time. To validate the performance of the proposed chosen-plaintext attack, numerous experiments were performed on two recently proposed permutation-only image/video ciphers. Both theoretical and experimental results showed that the proposed attack outperforms the state of the art cryptanalytic methods.

“…Protecting images captured by fingerprint sensors is a crucial factor because the transmission channel from the sensor to the database server may be vulnerable to attacks. However, conventional standard cryptographic methods could not be used due to the computational limitations of the sensor devices [2,3].…”

Robust lightweight fingerprint encryption using random block feedback

Fingerprint encryption in embedded environments should satisfy both lightweightedness and secureness. Normally, the encryption scheme divides the 8-bit pixel images into bit planes and then performs full encryption for one bit plane, e.g. least significant bit plane, and simple operations for the remaining bit planes. Thus, the scheme performs better compared with the 8-bit full encryption, while the security is decreased since only one bit plane is fully encrypted. An innovative fingerprint encryption scheme is proposed which supports better security while maintaining the overall performance. The proposed scheme uses a bit plane encryption and a random block feedback. The encryption schemes are implemented and tested with 320 sample fingerprint images. The result shows that the scheme has superior aspects compared with the existing bit plane encryption and even with the naive full encryption.
