Secure pattern matching using somewhat homomorphic encryption
TL;DR: This paper makes use of the somewhat homomorphic encryption scheme presented by Lauter, Naehrig and Vaikuntanathan (ACM CCSW 2011), which supports a limited number of both additions and multiplications on encrypted data and proposes a new packing method suitable for an efficient computation of multiple Hamming distance values onencrypted data.

Packed homomorphic encryption based on ideal lattices and its application to biometrics
TL;DR: This paper proposes an efficient method to compute the Hamming distance on encrypted data using the homomorphic encryption based on ideal lattices, and proposes a privacy-preserving biometric authentication protocol using this method, and compares it with related protocols.
Book ChapterDOI
Practical Packing Method in Somewhat Homomorphic Encryption
TL;DR: This paper focuses on the scheme proposed by Lauter, Naehrig and Vaikuntanathan (ACM CCSW 2011), and presents two types of packed ciphertexts based on their packing technique, giving practical size and performance for wider computations such as statistical analysis and distances.

New packing method in somewhat homomorphic encryption and its applications
TL;DR: This paper presents two types of packed ciphertexts, one of which is based on the message encoding technique proposed by Brakerski and Vaikuntanathan, and enables efficient secure computation of more complex functionalities such as multiple inner products and multiple Hamming distances.
