Abe

ABE is an acronym that can refer to several different things depending on the field and context. Notable uses include Adult Basic Education, Attribute-Based Encryption, and the IATA airport code for Lehigh Valley International Airport.

Adult Basic Education (ABE) refers to programs that help adults improve foundational skills such as literacy, numeracy, and language proficiency. These programs often aim to prepare participants for high school equivalency tests, entry into further education, job market readiness, or improved everyday functioning. ABE services are commonly offered by schools, community colleges, government agencies, and nonprofit organizations.

Attribute-Based Encryption (ABE) is a cryptographic paradigm in which access to encrypted data is controlled by attributes rather than by user identity alone. In CP-ABE (Ciphertext-Policy ABE) and KP-ABE (Key-Policy ABE) schemes, decryption requires possessing specific attributes or meeting a defined access policy. ABE enables fine-grained access control for secure data sharing, particularly in cloud storage and distributed systems.

Lehigh Valley International Airport uses the IATA code ABE. It serves the Allentown-Bethlehem-Easton region in Pennsylvania, United States, and functions as a regional airport for air travel, cargo, and related services.

In other contexts, ABE can stand for a variety of organization names, programs, or technologies, and its meaning is highly context-dependent. When encountering the term, the subject matter and surrounding terminology usually clarify which ABE is intended.
